Summary
Amoxicillin is an antibiotic used to treat bacterial infections. It is effective against many types of bacteria including those that cause infections like pneumonia, ear infections, and urinary tract infections.
Amoxicillin works similarly to penicillin. It kills bacteria by preventing them from building their protective walls. When these walls are damaged, the bacteria die.
Amoxicillin is available in capsules, tablets, and liquid forms. The dosage and length of treatment depend on the type of infection. It is usually taken for at least 2-3 days after you feel better or tests show the bacteria are gone. For stomach ulcers, it's typically taken for 14 days.
Common side effects of Amoxicillin include diarrhea, rash, vomiting, and nausea. Severe side effects can include severe skin reactions, serious intestinal infection, and allergic reactions.
Amoxicillin should not be taken by people who have had a severe allergic reaction to it or other similar antibiotics. It can cause serious skin reactions and a severe bowel condition. Always consult your doctor before taking Amoxicillin.
