Ask your pharmacist for specific safety questions on your specific drugs.

Yes these are the antibiotics which have the highest therapeutic index.. That too penicillin is exceptionally high... The only side effect which is considered significant from these two groups of antibiotics is Hypersensitivity reaction or allergis reaction which can be lethal also in some of them.. The reason is, both of these belong to a group of beta lactum antibiotics and they both have a protein structure and they are easily metabolised in the body.. If they ast on bacteria than they are antibiotics otherwise they are mere protein food, just like giving parentral nutrition... Hence they have a huge therapeutic index..
