Propranolol vs. Detrol

Propranolol is a non-selective beta blocker. It helps with a range of medical conditions, including high blood pressure, tremors, and migraine prevention. Sometimes, providers prescribe propranolol off-label to ease performance anxiety. You take this medication by mouth, typically 1 to 4 times daily, depending on if you're taking the immediate-release (IR) or extended-release (ER) medication. Keep in mind the IR and ER versions don't treat the same medical conditions. Some of the more common side effects of propranolol include dizziness, tiredness, or weakness.

Tolterodine (Detrol) is used to treat overactive bladder (OAB) in adults. It's an anticholinergic medication that helps with bladder control to lessen the need to go to the restroom suddenly or often. The immediate-release tablet (Detrol) is taken by mouth twice a day. There's also an extended-release capsule (Detrol LA) that's taken just once a day. Both formulations come in brand-name and generic-name versions. Tolterodine (Detrol) can commonly cause dry mouth. Other side effects can include headache and constipation.
