Overdose can cause nausea, vomiting, dilated pupils, weakness or loss of movement in any part of your body, trouble swallowing, fainting, or seizure (convulsions).

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.

May cause dizziness or blurred vision. Avoid driving or hazardous activity until you know how dicyclomine will affect you.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Dicyclomine can decrease sweating and you may be more prone to heat stroke. Tell your doctor if you have a fever while taking dicyclomine.

Avoid using an antacid. Antacids can make it harder for your body to absorb dicyclomine oral.

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

Dicyclomine may cause serious side effects. Call your doctor at once if you have:

• fast or slow heartbeats, pounding heartbeats or fluttering in your chest;

• confusion, agitation, hallucinations, unusual thoughts or behavior;

• problems with memory or speech;

• problems with balance or muscle movement;

• diarrhea, severe constipation, or worsening of bowel symptoms;

• trouble swallowing;

• bruising, swelling, or pain where a dicyclomine injection was given; or

• dehydration --dizziness, confusion, feeling very thirsty, less urination or sweating.

Confusion and mood or behavior changes may be more likely in older adults.

Common side effects of dicyclomine may include:

• drowsiness, dizziness, weakness, nervousness;

• blurred vision;

• dry mouth; or

• nausea.

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 dicyclomine 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.

Tell your doctor about all your current medicines. Many drugs can affect dicyclomine, especially:

• bronchodilator asthma medication;

• cold or allergy medicine (Benadryl and others);

• glaucoma medication;

• heart medication;

• medicine to treat depression, anxiety, mood disorders, or mental illness;

• medicine to treat overactive bladder;

• medicine to treat Parkinson's disease; or

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

This list is not complete and many other drugs may affect dicyclomine. 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.
