Pregnant women with tonsillitis can take amoxicillin, but it should be taken under the diagnosis of a doctor. Amoxicillin belongs to penicillin antibiotics, which inhibits the growth of bacteria by acting on the cell wall of bacteria. Because mammals have no cell wall, amoxicillin is safe. If pregnant women are infected, penicillins are the first choice. It is suggested that patients should consult a doctor to diagnose the indications of useful antibacterial drugs before choosing amoxicillin.
