whenever you have a question about medications remember you can always call a pharmacist. they truly are the drug experts and are always happy to answer your questions. plus you usually can reach one at any time of the day or night. assuming you're an otherwise healthy adult with no known drug allergies then you should be able to safely take an antihistamine (such as diphenhydramine) along with flonase sudafed and amoxicillin. flonase is a steroid nasal spray designed to help relieve allergy symptoms by shrinking inflamed tissue. sudafed is a decongestant which helps dry up excessive secretions. amoxicillin is an antibiotic. be sure to take all of your amoxicillin prescription. do not stop taking it just because you start feeling better. it's very important to take all of your antibiotic pills on the prescribed schedule. do not "save" any antibiotics for future use. this type of behavior contributes to the development of bacteria that resist treatment by antibiotics. i hope this helps!
i can take an antihistamine or any medicine while using flonase amoxicillin and sudafed
