How should I take Diamode?

Use exactly as directed on the label, or as prescribed by your doctor.

Diamode is safe when used as directed. TAKING TOO MUCH LOPERAMIDE CAN CAUSE SERIOUS HEART PROBLEMS OR DEATH.

Always follow directions on the medicine label about giving Diamode to a child. A safe dose of loperamide is different for an adult than for a child. Doses in children are based on the child's age.

Take Diamode with a full glass of water. Diarrhea can cause your body to lose fluids and electrolytes. Drink plenty of liquids to keep from getting dehydrated.

The Diamode chewable tablet must be chewed before swallowing.

Shake the oral suspension (liquid) before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Not all liquid forms of loperamide are the same strengths. Carefully follow all dosing instructions for the medicine you are using.

Store at room temperature away from moisture and heat. Do not allow the liquid medicine to freeze.

Stop taking Diamode and call your doctor if you still have diarrhea after 2 days of treatment, or if you also have stomach bloating.

What happens if I miss a dose?

Since Diamode is used when needed, it does not have a daily dosing schedule. Call your doctor if your symptoms do not improve after using Diamode.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of loperamide can be fatal.

Overdose symptoms may include fast or irregular heartbeats, or fainting. A person caring for you should seek emergency medical attention if you pass out and are hard to wake up.

What should I avoid while taking Diamode?

Avoid drinking tonic water. It can interact with Diamode and may cause serious heart problems.

Avoid becoming dehydrated by drinking plenty of fluids. Avoid vigorous exercise or exposure to hot weather if you are dehydrated.

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

What other drugs will affect Diamode?

Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take. Ask a doctor or pharmacist about safely using medications together.

Diamode can cause a serious heart problem. Your risk may be higher if you also use certain other medicines for infections, heart problems, depression, mental illness, cancer, malaria, or HIV.

Many drugs can affect Diamode. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here. Tell your doctor about all your current medicines and any medicine you start or stop using.
