Antibiotics are drugs that cure disease by killing bacteria or keeping it from reproducing and growing. The pharmacy offers a wide range of different antibiotics to cure minor and life-threatening infections, including fungal, viral and bacterial infections. It is important to remember that antibiotics only treat bacterial infections and are useless against viral infections and fungal infections. Each type of antibiotic is specific and there is no one type of antibiotic that cures every infection. Your doctor can best determine if a medication is right for your condition.
