What other drugs will affect propantheline?
Using propantheline with other drugs that make you drowsy can worsen this effect. Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety or seizures.
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.
Tell your doctor about all your current medicines. Many drugs can affect propantheline, especially:
heart rhythm medication;
medicine to treat depression, anxiety, mood disorders, or mental illness;
cold or allergy medicine (Benadryl and others);
medicine to treat Parkinson's disease;

bronchodilator asthma medication.
This list is not complete and many other drugs may affect propantheline. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
