Can I take vitamins during an antibiotics treatment with penicillin? Can you tell me a first aid for penicillin allergic reaction? Thank you :) Carol

Yes, and see below. So yes you can take vitamins while on antibiotics. The rationale is that when you go on system antibacterial agents like that you wipe out healthy flora in your gut and elsewhere. Vitamins, pro-vitamins and growth factors are synthesized by bacterial carpets (ie some B vitamins, riboflavin, thiamine, co-enzyme I & II and pyridoxine to name several). For PCN allergy; benadryl (diphenhydramine) & epinephrine.
