To minimize stomach upset, should I take Pepcid (famotidine) 20mg before or after Plavix?

Pepcid (famotidine) should. Either be given at night or twice per day. Once you have stable levels of medication in your blood stream, it doesn't matter how you time it with your Plavix (clopidogrel). The key is taking your Plavix (clopidogrel) with food. .
