I'm a 21 yr old female who was perscribed metotoprolol for a high hr due to panic attacks. now my hr can be high 40's low 50's at rest. is this ok?

Decrease dose: I might suggest you talk to your doc about lowering the dose of the metoprolol to see if that puts your heart rate in a more normal range (60-100). Or even do a trial off the medication and see if just the occasional Xanax (alprazolam) can control your anxiety symptoms.

The HR itself is slo: A HR of 40-50 BPM is a little too slow,so the dose needs be reduced;Additionally I am concerned about giving a young female in the childbearing age,this type of medication (a betablocker),which does cross the placenta and cause problems in an unborn child
