What should I avoid while taking propantheline (Pro-Banthine)?
Propantheline can cause side effects that may impair your vision, thinking, or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.
Avoid drinking alcohol. It can increase some of the side effects of propantheline.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Propantheline can decrease perspiration and you may be more prone to heat stroke.
What other drugs will affect propantheline (Pro-Banthine)?
Before using propantheline, tell your doctor if you regularly use other medicines that make you sleepy (such as cold or allergy medicine, sedatives, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by propantheline.
Propantheline slows the digestive tract, which can make it harder for your body to absorb any medicines you take by mouth. Tell your doctor if any of your oral medications do not seem to work as well while you are using propantheline.
Many drugs can interact with propantheline. Below is just a partial list. Tell your doctor if you are using:

- bladder or urinary medications such as darifenacin (Enablex), flavoxate (Urispas), oxybutynin (Ditropan, Oxytrol), tolterodine (Detrol), or solifenacin (Vesicare);
- a heart rhythm medication such as disopyramide (Norpace), quinidine (Quin-G), procainamide (Procan, Procanbid, Pronestyl), and others;
