In addition, it should be noted that amoxicillin belongs to antibiotics, which is the most common antibiotic and belongs to non-OTC drugs. In principle, the purchase requires a doctor's prescription, so the doctor will recommend precautions. But it's better to have the same batch from the same manufacturer, because their production comes from the same fermentation process, and there are relatively few hidden dangers to patients. In addition, due to the country's successive price reduction of antibiotics, hospitals and clinics are using antibiotics, especially this most common drug has little profit and many doctors will not recommend it. You need to explain it to the doctor yourself.
I wish you a speedy recovery!
