1. What are the common sense of safe medication use in daily life?

Medicines should be prepared at home: ① Medications for common diseases: common medicines for respiratory diseases such as colds, asthma, bronchitis; diarrhea and vomiting Commonly used drugs for digestive tract diseases such as , loss of appetite, etc.; others such as cod liver oil, calcium tablets, external medicines for ENT and dermatology diseases, etc.

②Commonly used medicines: There are many types of medicines for treating various systemic diseases, and only the commonly used medicines should be prepared at home. There are many drugs with similar effects, so just choose some for later use.

③Safe medicine: Children have strict medication requirements, and improper use can easily lead to adverse consequences. The backup medicines should be those with few side effects, small toxic reactions, and easy to use.

④Easy to use: The medicines commonly kept at home are mainly oral medicines and external medicines. Injectable drugs should be used as little as possible. Improper use and poor control may lead to allergic reactions and poisoning, which may lead to adverse consequences.

⑤Medicines that are easy to store: Household medicines generally need to be stored for a long time. This requires storing less medicine, especially medicines that are prone to deterioration and failure.

Specifically, tablets should be the main medicine, supplemented by liquid medicine. Choose medicines with better packaging for storage.

⑥Medicines that are easy to master: Each medicine has its own dosage, usage, indications and side effects, which is difficult for parents to master. Therefore, the medicines that should be prepared should be few and precise, with fewer types, easy to remember, easy to use, and less likely to make mistakes.

It is not advisable to eat sweets when taking cold medicine: Medical experiments have proven that if you take cold medicine containing acetaminophen on an empty stomach, it usually only takes about 20 minutes for the drug concentration in the blood to reach the highest level. . When the patient has sugary food in his stomach, the absorption of cold medicines will be delayed by 2 hours, affecting their effectiveness.

Eating too much sweets will also cause a large amount of sugar to enter the blood, causing the patient to have a worse appetite. In addition, after the sugar in sweets enters the human body, it can also promote the secretion of cortisol. Cortisol has an inhibitory effect on the immune system and will significantly reduce the patient's body resistance. Therefore, remember not to take sweets and sweet drinks when you have a cold.

It is not advisable to drink fruit juice or milk when taking antibiotics: Chinese people have to take antibiotics for almost all major and minor illnesses to feel at ease. Regardless of whether taking antibiotics is the right thing to do, remember not to drink juice or milk within 2 hours before and after taking antibiotics.

This is because fruit juice, especially fresh fruit juice, is rich in fruit acid, which can accelerate the dissolution of antibiotics, reduce the efficacy of antibiotics, and may also produce harmful intermediates and increase toxic and side effects; while milk It will reduce the activity of the antibiotic, prevent the drug from fully exerting its efficacy, and thus fail to achieve the desired therapeutic effect. It is not advisable to drink milk when taking antidiarrheal medicine: During diarrhea, our appetite often decreases. In order to supplement the lost nutrients, we often drink milk with higher nutritional value to replace food.

Therefore, you must not drink milk during diarrhea. It is not advisable to drink coffee or cola when taking ibuprofen: ibuprofen is what we often call fenbid. It has anti-inflammatory, analgesic, and antipyretic effects.

It can play a certain therapeutic role in headaches, joint pain, toothache, colds and fever. However, since ibuprofen itself is highly irritating to the gastric mucosa, in order to avoid aggravating the pain, we should try to avoid drinking drinks such as coffee and cola that can stimulate gastric acid secretion, so as not to aggravate the irritation of ibuprofen to the gastric mucosa. It has toxic side effects and even induces gastric bleeding and gastric perforation.

It is not advisable to eat grapefruit when taking antihypertensive drugs: Doctors suggest that it is best not to eat grapefruit or drink grapefruit juice while taking antihypertensive drugs. If you must eat grapefruit, you should take corresponding antihypertensive drugs 12 hours after eating grapefruit.

This is because grapefruit contains a chemical called furanocoumarins, which can affect the function of an enzyme in the liver, greatly reducing the metabolic effect of this enzyme on drugs, causing blood poisoning in the body. Concentration increases. At the same time, the naringenin in grapefruit will speed up the intestinal absorption of drugs.

Too fast drug absorption and too slow metabolism will lead to high drug concentration in the blood. If antihypertensive drugs are taken together with grapefruit, patients will experience some reactions to drug overdose, including a drop in blood pressure, a slowdown in heart rate, and even shock in severe cases.

It is not advisable to eat bananas and oranges when taking diuretics: Diuretics are commonly used drugs in clinical practice, but everyone needs to be aware that potassium will remain in the blood while taking diuretics. Bananas, oranges and other fruits contain high levels of potassium. After taking them, patients will accumulate too much potassium in their bodies, which can easily induce heart and blood pressure complications.

3. What are the essential medicines commonly used by ordinary people?

Take stock of the essential medicines at home. With the gradual improvement of people’s living standards and the continuous popularization of medical and health knowledge, people have to prevent diseases. The awareness of fitness has increased, and many families are equipped with medicines, so that some minor illnesses can be treated in time.

However, any drug has two sides. It can cure diseases and harm human health. Therefore, a small amount of relatively safe and effective commonly used drugs should be prepared in a targeted manner according to the health status of family members, and they should learn to use them scientifically and rationally.

Families can generally stock the following types of medicines. (1) Antipyretic and analgesic drugs: such as aspirin, painkillers, indomethacin, etc.

(1l) External analgesics: such as rheumatism ointment, safflower oil, etc. (12) Others: Band-Aids, essential oil, cooling oil, disinfectant cotton swabs, gauze, tape, etc.

4. What are the necessary medicines for daily life?

Thermometer, band-aid, sterile gauze bandage, round-head scissors, pliers, disposable gloves, antibiotic ointment, aspirin, painkillers, anti-inflammatory Pain, cardiovascular and cerebrovascular drugs, blood pressure monitors, blood glucose meters, cold, fever reducing, cough relieving, antiasthmatic drugs, etc.

List of essential medicines in a home first aid kit: 1. First aid manual According to statistics from the International Red Cross, only 12% of adults in the world are able to take emergency rescue measures in emergencies, and only 5% of them The measures are effective. Many families have a lot of first aid kits, but they don’t know how to do it.

The lack of first aid knowledge makes many of us at a loss when an accident occurs, so a first aid manual is the most important. First aid manuals can be purchased in general bookstores, or can be downloaded and bound online.

2. When using a mercury thermometer, you must first shake off the mercury column and wipe off the armpit sweat clip for 10 minutes; when using an electronic thermometer, place the probe where the temperature needs to be measured until Hear the beep and read the measurement value. Household electronic thermometers also have a service life, which is generally about 5 years.

3. Band-Aids are used for small wounds and wound dressings, and are available in various sizes: large, medium and small. Waterproof band-aids and medicated band-aids must be prepared.

4. Sterile gauze is used to cover the wound. It is not likely to leave cotton threads on the wound like cotton, and it will not affect the wound when removed.

You can also use a bandage. The bandage is elastic and can be used to wrap the wound without hindering blood circulation. The 2-inch size is suitable for hands, and the 3-inch size is suitable for feet.

5. Triangular bandage, also called triangular bandage, has many uses. It can support injured upper limbs, fix dressings or fractures, etc. 6. Round-head scissors, pliers, disposable gloves. Round-head scissors are safer and can be used to cut tape or bandages.

It can also be used to cut clothes when necessary. Pliers can replace holding dressings with both hands, or clamping to remove dirt from wounds, etc.

Disposable gloves can prevent the human body from direct contact with wounds and avoid cross-infection. 7. Masks are mainly used to isolate the wound surface from contamination of oral and nasal gases. It should be reminded that you must wash your hands before and after wearing it, and replace it immediately after wearing it once.

8. A flashlight can be used to provide lighting when rescuing in a dark environment, and it can also be used to perform pupillary reactions on people who have fainted. 9. 0.9% saline is used to clean wounds.

Based on hygiene requirements, it is best to choose individual small packages or medium-sized bottles. It should be noted that any leftovers after opening should be thrown away and should not be put into the first aid kit again.

If not available, unopened distilled or mineral water can be used instead. 10. Disinfecting paper towels are used to clean the skin, sterilize and disinfect. Just tear off the package and apply it directly to the skin.

11. Use plastic wrap to wrap burns and scalds before sending them to the hospital. 12. Ice packs can be placed on bruises, muscle strains or joint sprains to shrink capillaries and help reduce swelling.

When a nose bleeds, place it on the injured person’s forehead to help stop the bleeding. 13. Antibiotic ointments, such as chlortetracycline ointment and erythromycin ointment, are used for bruises on knees and elbow joints to protect the exposed inner skin.

Note: Do not use antibiotics casually, please read the instructions clearly. Or as directed by your doctor.

Topical antihistamines and aspirin (or other over-the-counter analgesics) Antihistamines are mainly used to fight allergies, such as chlorpheniramine, astemizole (astemizole), Diphenhydramine etc. Analgesics such as aspirin, pain relievers, indomethacin, etc. are used to relieve mild to moderate pain, such as headache, joint pain, toothache, muscle pain, neuralgia, and dysmenorrhea. A sufficient supply should be prepared for at least three to five days. .

If there is no improvement after 5 hours of taking the medicine, please go to the hospital as soon as possible to avoid delaying the condition. It should be reminded that the medicines in the home first aid kit should be cleared out every 3 to 6 months.

If your family members have various chronic diseases, heart disease, etc., you should also replenish the first aid kit for individual situations. What medicines should be kept on hand if there are elderly people at home? 1. Cardiovascular and cerebrovascular drugs. Nine out of ten elderly people today suffer from cardiovascular diseases. In addition to the drugs that need to be taken according to the doctor's instructions, you may wish to prepare more nitroglycerin at ordinary times. Once you feel chest tightness, heart discomfort, or angina pectoris, , then take it immediately.

Nowadays, there is a new spray of nitroglycerin, which only needs to be sprayed twice, which is more convenient. If parents suffer from cerebrovascular disease, their children can prepare some Angong Niuhuang Pills at home. If they find signs of stroke, such as sudden slurred speech or speechlessness, it is best for them to take one pill.

2. Digestive drugs Poor gastrointestinal function is also a common problem for the elderly. On the one hand, they are prone to flatulence after eating, so they can prepare some gastrointestinal motility drugs such as domperidone; on the other hand, constipation is not a serious problem, but many elderly people die suddenly due to it.

Therefore, you should prepare some laxatives, such as Kaiselu. 3. Sphygmomanometer and blood glucose meter. For blood pressure monitors, it is best for elderly people with bad ears to choose electronic ones, as their accuracy is generally not a problem.

When you feel that you have uncomfortable symptoms such as dizziness and chest tightness, it is best to take a measurement in time. In addition, it is best to measure your blood pressure after getting up in the morning in order to detect abnormalities earlier.

A blood glucose meter is a must-have for diabetic patients. It can be measured anytime and anywhere when you feel uncomfortable. 4. Oxygen bag: It is recommended for patients with heart disease or poor lung function to prepare one.

However, it should be noted that the oxygen bag can only solve the "temporary pain". Once the symptoms are relieved, you must go to a regular hospital for treatment. 5. Thermometer: The elderly are not as sensitive to changes in their own body temperature as before, and most of the time they do not feel that they have a fever.

Therefore, when the elderly are in low spirits and have no appetite, it is best to take their temperature first to see if a fever is the "trouble". Moreover, fever is the "vanguard" of many major diseases and should not be taken carelessly.

In addition, cold, fever-reducing, cough-relieving, and anti-asthmatic drugs can also be used for many years. Experts remind that home medicine kits are for emergency use. If sudden symptoms are relieved after taking medicine, you should still go to the hospital for a systematic check-up to avoid missing out on good treatment opportunities.

Many elderly people get sick suddenly, so you need to pay attention to the placement and use of small family medicine boxes: 1. Children should put the medicine box at the bedside of the elderly. If the illness occurs at night, they can reach it with just a hand. 2. Check for expired medicine every 3 months.

3. Try to choose over-the-counter medicines, because they are generally effective and simple to use, and commonly used medicines are best used in small quantities and not in excessive amounts. The most important thing is whether they can "cure the disease".

5. Medical knowledge

Medical knowledge Aspirin conflicts with alcohol. Wine is first oxidized into acetaldehyde and then acetic acid in the body, and aspirin will prevent the oxidation of acetaldehyde into acetic acid, causing accumulation of acetaldehyde in the body, aggravating symptoms such as fever and general pain, and easily causing liver damage. Berberine conflicts with tea. Tea contains about 10% tannins, which are easily decomposed into tannic acid in the body, and tannic acid will precipitate the alkaloids in berberine and reduce its efficacy. Therefore, you should not drink tea within 2 hours before and after taking berberine.

Ibuprofen conflicts with coffee and cola. Ibuprofen (Fenbid) has an irritating effect on the gastric mucosa. The caffeine in coffee and cocaine in cola will irritate gastric acid secretion, aggravate the side effects of ibuprofen on the gastric mucosa, and even induce gastric bleeding, Gastric perforation. Antibiotics conflict with milk and juice. Do not drink milk or fruit juice 2 hours before and after taking antibiotics, because milk will reduce the activity of antibiotics and prevent the medicine from fully exerting its effect; fruit juice (especially fresh fruit juice) is rich in fruit acid, which will accelerate the dissolution of antibiotics, not only reducing the medicine's effectiveness, but also possibly Increase toxic and side effects.

Calcium tablets conflict with spinach. Spinach contains a large amount of potassium oxalate. After entering the body, the electrolyzed oxalate ions will precipitate calcium ions, hindering the body's absorption of calcium and easily forming calcium oxalate stones. Do not eat spinach within 2 hours before and after taking calcium tablets, or boil the spinach before eating it.

Anti-allergy medicines conflict with cheese and meat products. Avoid eating foods rich in histidine such as cheese and meat products while taking anti-allergic drugs. Because histidine is converted into histamine in the body, and anti-allergic drugs inhibit the decomposition of histamine, causing histamine accumulation and inducing uncomfortable symptoms such as dizziness, headache, and palpitation.

Antidiarrheal medicine conflicts with milk. Do not drink milk when taking antidiarrheal medicine, because milk not only reduces the efficacy of antidiarrheal medicine, but also contains lactose that can easily aggravate diarrhea.

Diuretics conflict with bananas and oranges. While taking diuretics, potassium will remain in the blood. If you eat bananas and oranges rich in potassium, excessive potassium accumulation in the body can easily induce heart and blood pressure complications.

Vitamin C conflicts with shrimp. Do not eat shrimp within 2 hours before and after taking vitamin C, because the copper in shrimp will oxidize vitamin C and make it lose its efficacy. The pentavalent arsenic in shrimps easily reacts with vitamin C to form toxic "trivalent arsenic".

Antihypertensive medications conflict with grapefruit juice. Do not drink grapefruit juice when taking antihypertensive drugs, because the naringenin in grapefruit juice will affect the function of a certain enzyme in the liver, and this enzyme is related to the metabolism of antihypertensive drugs, which can easily cause the drug concentration in the blood to be too high, increasing the side effect.

6. Basic knowledge of pharmacy

Let me briefly talk about my thoughts. This topic is relatively large. Indeed, there are too many pharmaceuticals in daily life and it is too complicated, but I think It’s about what kind of changes medicine has brought to our lives and what inspirations it has given me. One thing I feel most deeply and is the most important is that safe, effective, reasonable and economical medication is beneficial to every patient. Or let’s talk about the importance of every life! Drugs are used to save people, but in life or in clinical practice, a considerable number of patients actually die not from the disease itself, but from medical accidents or irrational use of drugs. I have seen more than one case. Two cases, so medicine made me know the importance of life and cherish life! This is the original intention of mankind to invent drugs, the purpose is to make everyone in the world healthy.

I personally think that if you think carefully about this article, you should not just read it casually on the Internet. The pharmacy in life should be found in life, such as going to a pharmacy for internship, going to a hospital for further training, or going to a pharmaceutical factory for exercise. . Only in this way can you truly understand what life medicine allows you to know. After all, the contact surface in school is limited.

Everyone’s experience is different. I only talk about my personal experience and it may not be suitable for your article writing. The score is not a problem. You can give it or not. I just hope that what I say can Helpful for you. Remember the saying that things in life must be found and experienced in life! This is a very good topic. It is best to collect more information before writing it when everything is mature.

7. Management knowledge of commonly used drugs

1. What is drug classification management knowledge? Drug classification management is an internationally accepted management method.

It is based on the principles of safety and effectiveness of drugs, and according to their varieties, specifications, indications, dosages and routes of administration, etc., the drugs are classified into prescription and over-the-counter drugs and managed accordingly. Regulation. Since the founding of the People's Republic of China, our country has first implemented the classified management of drugs, drugs, medical toxic drugs, radioactive drugs and detoxification drugs. The core of the ongoing classified management of prescription drugs and over-the-counter drugs is to strengthen the management of prescription drugs and standardize them. The management of over-the-counter drugs reduces the occurrence of irrational drug use and effectively ensures the safety and effectiveness of people's medication.

2. What are prescription drugs and over-the-counter drugs? Prescription drugs are drugs that can only be prepared, purchased and used with a prescription from a licensed physician or licensed assistant physician. Non-prescription medicines refer to medicines that can be judged, purchased and used by oneself without a prescription from a licensed physician or licensed assistant physician.

Prescription drugs are called Preseription Drug or Ethical Drug in English, and over-the-counter drugs are called Nonpreserip Drug in English. In the United States, they are also called "drugs that can be purchased over the counter (Over The Corner)" or OTC for short. This has become a global Common name. 3. How to identify over-the-counter drugs? (1) Article 7 of the "Measures for the Classification and Management of Prescription and Over-the-Counter Drugs" (Trial) stipulates that the packaging of over-the-counter drugs must be printed with the nationally designated proprietary label for over-the-counter drugs (OTC).

(2) Article 7 of the "Interim Provisions on the Circulation Management of Prescription and Over-the-Counter Drugs" (Trial) states: For over-the-counter drugs that enter the field of drug circulation, the corresponding warnings should be conspicuously printed on the drug packaging by the manufacturer. or in the drug instructions for use. The specific content is: Please read the drug instructions carefully and use it according to the instructions or purchase and use it under the guidance of a pharmacist! 4. What is safe and rational drug use? Safe and rational drug use should be done: appropriately select drugs according to the condition, patient's constitution and the overall situation of the drug, truly "prescribe the right medicine to the case", and at the same time, use the drug accurately at the appropriate dose and at the appropriate time.

Pay attention to the contraindications, adverse reactions, interactions, etc. of this drug. And also be careful to spend as little money as possible.

In this way, medication can be used safely, reasonably, effectively and economically. 5. How to read drug instructions accurately? Drug instructions are one of the bases for guiding how to use drugs and have legal effect.

Accurately reading and understanding the instructions before taking medication is a prerequisite for safe medication use. First you should know the name of the medicine.

Regular drug instructions include the generic name, trade name, English name, and chemical name of the drug (over-the-counter drugs have no chemical name). Generally, users can avoid repeated use of drugs as long as they know the correct name of the drug, that is, the generic name.

Because a drug has only one common name (that is, the legal name specified by the state), unlike several trade names. In the indication column, patients who use over-the-counter drugs can self-judge whether their disease is consistent with the indications and prescribe the right medicine. They can choose to purchase it with the help of a pharmacist.

Secondly, you must understand the usage of the medicine, such as taking it before meals, after meals, before going to bed, once or three times a day, and whether it is taken orally, for external use or for injection, you must carefully check it. Third, pay attention to the dosage of the drug and apply it according to the instructions.

Generally, the dosage instructions are for adults, and the elderly and children must accurately convert them before taking them. It is particularly important to pay attention to contraindications, adverse reactions, drug interactions, precautions, etc. when reading the instructions. If there is anything unclear, you should consult a pharmacist or physician.

6. Why are over-the-counter drugs divided into Category A and Category B? What is its logo? One of the reasons for implementing drug classification management is to facilitate the general public. Some minor injuries and illnesses can be purchased nearby, eliminating the need for time off, missed work, time, money, and effort. In order to make it more convenient for the public, the safety of over-the-counter drugs is also included. Some higher drugs are classified as Category B, which can be sold in supermarkets, hotels, and department stores. The OTC logo of Category A is red, and the OTC logo of Category B is green. 7. How to identify the expiration date of medicines? The validity period refers to the approved period of use of the drug, which means the period during which the quality of the drug can be guaranteed under certain storage conditions. The expiration date of the drug is expressed in the order of year and month. Generally, the validity period is until a certain month of a certain year. For example, the validity period is until 2003. June 2003, indicating that the drug will begin to expire on July 1, 2003.

The "Drug Administration Law" also stipulates that the production batch number, production date and expiration date should be marked on the packaging box or instructions of the drug. Imported drugs must also be written in Chinese according to the above-mentioned method to facilitate public reading.

8. Do OTC drugs have no serious adverse reactions? Over-the-counter drugs are also medicines themselves. Generally speaking, the adverse reactions are less and mild, but not absolute. Some over-the-counter medicines can cause serious adverse reactions in a small number of people, and sometimes even cause death. Therefore, over-the-counter medicines should also be taken in accordance with the instructions for use. Do not increase the frequency of taking or change the method or route of medication.

9. What is an allergic reaction to drugs? Drugs are a kind of foreign "foreign body" to people. The human body is born with the ability to respond to "foreign bodies", which is originally a self-protection ability of the body. However, if this reaction exceeds a certain limit, it will cause harm to the body.

An allergic reaction is an excessive reaction of the human body to a drug. It is essentially an immune reaction. Drug allergic reactions are adverse drug reactions.

10. How to choose drugs safely and rationally? First of all, you should diagnose your disease, and then prescribe the right medicine. You can't just take medicine based on your own feeling or a certain symptom. For example, fever and headache are common symptoms of many diseases.

You cannot simply take some painkillers to reduce fever; another example is abdominal pain, which is also the first symptom of some diseases. If painkillers are used indiscriminately, it will cover up some symptoms of acute abdomen and delay the patient's health. illness resulting in serious consequences. The second step is to understand the nature, characteristics, indications, adverse reactions, etc. of the drug, and choose drugs with good efficacy and low toxicity. This is the reason why doctors often refer to "first-line drugs" and "second-line drugs".

For example, there are many types of analgesics. For common colds, headaches, joint pain, neuropathic pain, and women’s menstrual abdominal pain, you can choose acetaminophen (paracetamol), Fenbid, Sanli Pain, Aspirin and any of them; for abdominal pain caused by gastrointestinal spasm, belladonna and atropine can be used.
