Brief Answer:
You'd better avoid taking the pill tonight

Detailed Answer:
Hello,

dilaudid may cause tachycardia or bradycardia. In your case it has probably contributed to your bradycardia. Since your heart rate is as slow as 45/minute, I would suggest avoiding taking metoprolol tonight, althouth this might raise your heart rate. Having very slow pulse rate (below 40/minute) or a slow pulse rate with symptoms (faintness, sweating, etc) would be a reason to go the emergency room at once. Since you're very close to that (45-47/minute), taking more metoprolol would be a risk.

If you don't have any serious heart disease (for example, serious heart failure that's easily decompensated) then you don't have to worry about missing the pill once.

I hope I've helped!

Kind Regards!
