Diastop

Diastop is indicated as an adjunct to rehydration in acute

diarrhea. It is used as a symptomatic treatment in chronic

mild ulcerative colitis.

Diastop is used also for the control of stool formation

after colostomy or ileostomy.

Atropine (Diastop) affects the body in many different ways, such as reducing spasms in the bladder, stomach, and intestines.

Diphenoxylate (Diastop) is an antidiarrheal medication.

The combination of Atropine (Diastop) and Diphenoxylate (Diastop) is used to treat diarrhea.

Atropine (Diastop) and Diphenoxylate (Diastop) may also be used for other purposes not listed in this medication guide.

DO NOT EXCEED RECOMMENDED DOSAGE.

Adults: The recommended initial dosage is two Diastop tablets four times daily or 10 ml (two regular teaspoonfuls) of Diastop liquid four times daily (20 mg per day). Most patients will require this dosage until initial control has been achieved, after which the dosage may be reduced to meet individual requirements. Control may often be maintained with as little as 5 mg (two tablets or 10 ml of liquid) daily.

Clinical improvement of acute diarrhea is usually observed within 48 hours. If clinical improvement of chronic diarrhea after treatment with a maximum daily dose of 20 mg of Diphenoxylate (Diastop) hydrochloride is not observed within 10 days, symptoms are unlikely to be controlled by further administration.

Children: Diastop is not recommended in children under 2 years of age and should be used with special caution in young children. The nutritional status and degree of dehydration must be considered. In children under 13 years of age, use Diastop liquid. Do not use Diastop tablets for this age group.

Only the plastic dropper should be used when measuring Diastop liquid for administration to children.

Dosage schedule for children: The recommended initial total daily dosage of Diastop liquid for children is 0.3 to 0.4 mg/kg, administered in four divided doses. The following table provides an approximate initial daily dosage recommendation for children.

These pediatric schedules are the best approximation of an average dose recommendation which may be adjusted downward according to the overall nutritional status and degree of dehydration encountered in the sick child. Reduction of dosage may be made as soon as initial control of symptoms has been achieved. Maintenance dosage may be as low as one-fourth of the initial daily dosage. If no response occurs within 48 hours, Diastop is unlikely to be effective.

KEEP THIS AND ALL MEDICATIONS OUT OF THE REACH OF CHILDREN.

What is the most important information I should know about Diastop?

Diastop is contraindicated in patients with

1. Known hypersensitivity to Diphenoxylate (Diastop) or Atropine (Diastop).
2. Obstructive jaundice.
3. Diarrhea associated with pseudomembranous enterocolitis or enterotoxin-producing bacteria.

Use Diastop solution as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Take Diastop solution by mouth with or without food.
• Use the dropper than comes with Diastop solution to measure your dose. Ask your pharmacist for help if you are unsure of how to measure your dose.

What other drugs will affect Diastop?

Known drug interactions include barbiturates, tranquilizers, and alcohol. Diastop may interact with MAO inhibitors.

In studies with male rats, Diphenoxylate (Diastop) hydrochloride was found to inhibit the hepatic microsomal enzyme system at a dose of 2 mg/kg/day. Therefore, Diphenoxylate (Diastop) has the potential to prolong the biological half-lives of drugs for which the rate of elimination is dependent on the microsomal drug metabolizing enzyme system.

Drug Abuse And Dependence

Controlled Substance

Diastop is classified as a Schedule V controlled substance by federal regulation. Diphenoxylate (Diastop) hydrochloride is chemically related to the narcotic analgesic meperidine.

Drug Abuse And Dependence

In doses used for the treatment of diarrhea, whether acute or chronic, Diphenoxylate (Diastop) has not produced addiction.

Diphenoxylate (Diastop) hydrochloride is devoid of morphine-like subjective effects at therapeutic doses. At high doses it exhibits codeine-like subjective effects. The dose which produces antidiarrheal action is widely separated from the dose which causes central nervous system effects. The insolubility of Diphenoxylate (Diastop) hydrochloride in commonly available aqueous media precludes intravenous selfadministration. A dose of 100 to 300 mg/day, which is equivalent to 40 to 120 tablets, administered to humans for 40 to 70 days, produced opiate withdrawal symptoms. Since addiction to Diphenoxylate (Diastop) hydrochloride is possible at high doses, the recommended dosage should not be exceeded.
