Drug-Induced Nightmares

Q. I stopped taking Toprol because I had nightmares while taking it. I have talked to three other people who also have nightmares and take this drug.
A. Drug-induced nightmares are often overlooked. Many medications, including beta blockers like metoprolol (Toprol XL) and propranolol (Inderal) as well as the stop-smoking drug varenicline (Chantix), are reported to cause disturbing dreams. Stopping a beta blocker like Toprol suddenly is not a good idea. If nightmares are disrupting your sleep please discuss this side effect with your prescriber.
