Interactions between your drugs
diphenhydramine ↔ tiotropium
Applies to:Benadryl (diphenhydramine) and Spiriva (tiotropium)
Talk to your doctor before using diphenhydrAMINE together with tiotropium. Although side effects are generally uncommon with inhaled preparations because very little of the medication gets absorbed into the bloodstream from the lungs, they can occur occasionally (especially in the elderly), and the risk may be increased when used with other medications. Some of the side effects include drowsiness, blurred vision, dry mouth, heat intolerance, flushing, decreased sweating, difficulty urinating, abdominal cramping, constipation, rapid heart beat, confusion, memory problems, and glaucoma. You should keep your eyes closed when using an inhaled product to keep the medication from getting into the eye. Avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
