Can i take pepcid (famotidine) and sudafed together?

No known interaction: You should be safe especially if you have had no problem with either individually and follow directions. If you are still a bit worried and have a doctor, nurse or pharmacist you trust you can ask them too. But it should be fine. I hope you feel better soon.

Drugs.Com: drug interaction checker did not show any significant interactions between Pepcid (famotidine) & Sudafed Congestion (pseudoephedrine). However, there are many different formulations of sudafed. So, if not using plain sudafed would check the formulation specifically.
