What should I avoid while I'm on Helidac Therapy?

While taking Helidac Therapy to treat peptic ulcers, you should avoid products that contain alcohol or propylene glycol, because the combination can produce a violent reaction that includes vomiting and sweating. You should also avoid prolonged exposure to sunlight, because the therapy makes you sensitive to ultraviolet light, and any medications that may interact with the three drugs that make up Helidac Therapy: bismuth subsalicylate, metronidazole and tetracycline. Medications that can interact include:
  • disulfiram (Antabuse)
  • penicillin
  • certain anticoagulants, such as warfarin (Coumadin, Jantoven)
  • aspirin or products that contain aspirin
  • cimetidine (Tagamet)
  • lithium (Eskalith, Lithobid)
  • omeprazole (Prilosec, Zegerid)
  • phenobarbital (Luminal)
  • phenytoin (Dilantin, Phenytek)
  • probenecid (Col-Probenecid, Probalan)
  • sulfinpyrazone
  • diabetes medications
You should avoid taking certain antacids at the same time as a dose of Helidac Therapy. Take antacids containing aluminum, calcium, magnesium or sodium bicarbonate one to two hours before or one to two hours after a dose of Helidac Therapy. Use the same timing for zinc supplements. Foods that contain calcium should be taken at least two hours before or one hour after Helidac Therapy. Iron supplements should be taken at least three hours before or two hours after.

You should also avoid becoming pregnant, since Helidac Therapy may harm a developing fetus.
