You can eat oranges after taking amoxicillin. The absorption of amoxicillin is less affected by food, so it does not matter if you take the medicine before or after meals, and oranges will not affect the absorption of amoxicillin. It should be noted that amoxicillin belongs to the antibiotic class of drugs, and antibiotics must be taken according to medical advice, not on your own. In addition, antibiotics have requirements for dosage and course of treatment, which should be strictly enforced, otherwise they will not only be ineffective but also produce drug resistance. Amoxicillin belongs to the penicillin class of antibiotics and is prohibited for patients who are allergic to penicillin or cephalosporins. Before using the drug, you should know the allergy history in detail and do penicillin skin test if necessary to prevent the occurrence of allergic reactions.
