Yes. Cephalexin has no sulfa derivatives. Rather, it more closely resembles the penicillin/amoxicillin antibiotics. If you have an alergy to those, however, you may have some unpleasant side effects/reactions. Don't be afraid to call your doctor or pharmacist to ask questions before taking any medication.

Can you take Adderall if you are allergic to sulfa drugs?

Yes you can take adderall. adderall is not a sulfa (short for sulfonamide) drug. Adderall contains a sulfate (salt) . This is very different from sulfa drugs which actually contain sulfur. the chemical structures of these drugs are very different. Sulfonamides have the structure (R-SO2-NH2) whereas adderall's structure is (C9H13N) so there is no cross-reactivity seen between these 2 classes of drugs. Look on the wikipedia site under sulfa drugs to see a list of all the (sulfa) drugs that would cause an allergic reaction. It shows a list of antibiotic and non-antibiotic sulfonamides. This does not mean that you can not have a reaction to adderall but it would be for a dfferent reason.
