I might have accidentally taken 25mg lopressor (metoprolol tartrate). I usually take 2 25mg. Will I be ok? Xx

It . It is unlikely that a single dose of 25 mg will cause any significant problem. Monitor your heart rate. If it becomes dramatically lower than usual or if you develop any dizziness, lie down and have someone drive you to be evaluated. If ther is no one to drive you, call 911.
