Can i take a bisoprolol with klonopin (clonazepam)?

You can, BUT: There may be additive, blood pressure-reducing effects when taking both these medications. Until you learn how the combination affects you, be cautious when getting up from a laying or sitting position. Report any symptoms like dizziness, lightheadedness, fainting, or tachycardia to your physician -- who should also be checking orthostatic blood pressures with you.
