Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

Unless your doctor tells you otherwise, continue your normal diet.

Avoid driving or hazardous activity until you know how propantheline will affect you. Your reactions could be impaired.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Propantheline can decrease perspiration and you may be more prone to heat stroke.

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Propantheline may cause serious side effects. Stop using propantheline and call your doctor at once if you have:

• diarrhea;

• fast or pounding heartbeats, fluttering in your chest;

• eye pain or redness, seeing halos around lights;

• painful or difficult urination; or

• little or no urination.

Common side effects of propantheline may include:

• dry mouth, nose, or throat;

• blurred vision;

• constipation;

• headache, dizziness, drowsiness;

• confusion or feeling nervous;

• decreased sweating;

• nausea, vomiting, bloating;

• decreased sense of taste;

• impotence, sexual problems; or

• sleep problems (insomnia).

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

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;

• steroid medicine;

• medicine to treat stomach problems, motion sickness, or irritable bowel syndrome;

• medicine to treat overactive bladder; or

• 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.

Keep all appointments with your doctor.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
