I took famotidine and now my bp is 134/86 and my hr is 98 resting. is this normal or should i be worried?

Get multiple readings at rest, and in a neutral sitting position first, if readings are still high see a cardiologist, it us unlikely the medicine is causing tachycardia or high BP - more likely you need a Biometric profile analyzed to see the underlying cause of this

There is no direct connection between famotidine, a pill used for stomach issues/ reflux and borderline blood pressure. Anxiety is likely contributing as isolated blood pressure readings or heart rates may be circumstantial and hard to explain out of context. Talk to your doc about your worries.
