What is Reglan® (metoclopramide) used for?
Reglan® increases muscle contractions in the upper digestive tract. This speeds up the rate at which the stomach empties into the intestines.
Reglan® may also be used for purposes not listed in this medication guide.
How should I take Reglan® (metoclopramide)?
Take Reglan® exactly as prescribed by your doctor. Reglan® is usually taken for only 4 to 12 weeks. Follow the directions on your prescription label.
Never take Reglan® in larger amounts than recommended, or for longer than 12 weeks.
High doses or long-term use of Reglan® can cause a serious movement disorder that may not be reversible. Symptoms of this disorder include uncontrollable muscle movements of your lips, tongue, eyes, face, arms, or legs. The longer you take Reglan®, the more likely you are to develop a serious movement disorder. The risk of this side effect is higher in women, diabetics, and older adults.
Take Reglan® 30 minutes before eating. Reglan® is usually taken before meals and at bedtime. Your doctor may want you to take the medication as needed only with meals that usually cause heartburn. Follow your doctor’s instructions.
Measure the liquid medicine with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
Do not take two different forms of Reglan® (such as tablets and oral syrup) at the same time.
How do I store Reglan® (metoclopramide)?

There may be different brands of Reglan® that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

What is the dose of Reglan® (metoclopramide) for an adult?
For the Relief of Symptoms Associated with Diabetic Gastroparesis (Diabetic Gastric Stasis)
If only the earliest manifestations of diabetic gastric stasis are present, oral administration of metoclopramide may be initiated. However, if severe symptoms are present, therapy should begin with Reglan® Injection (IM or IV). Doses of 10 mg may be administered slowly by the intravenous route over a 1- to 2-minute period.
Administration of Reglan® Injection (metoclopramide injection, USP) up to 10 days may be required before symptoms subside, at which time oral administration of metoclopramide may be instituted. The physician should make a thorough assessment of the risks and benefits prior to prescribing further metoclopramide treatment.
For the Prevention of Nausea and Vomiting Associated with Emetogenic Cancer Chemotherapy
Intravenous infusions should be made slowly over a period of not less than 15 minutes, 30 minutes before beginning cancer chemotherapy and repeated every 2 hours for two doses, then every 3 hours for three doses.
The initial two doses should be 2 mg/kg if highly emetogenic drugs such as cisplatin or dacarbazine are used alone or in combination. For less emetogenic regimens, 1 mg/kg per dose may be adequate.
For doses in excess of 10 mg, Reglan® Injection should be diluted in 50 mL of a parenteral solution.
The preferred parenteral solution is Sodium Chloride Injection (normal saline), which when combined with Reglan® Injection, can be stored frozen for up to 4 weeks. Reglan® Injection is degraded when admixed and frozen with Dextrose-5% in Water. Reglan® Injection diluted in Sodium Chloride Injection, Dextrose-5% in Water, Dextrose-5% in 0.45% Sodium Chloride, Ringer’s Injection, or Lactated Ringer’s Injection may be stored up to 48 hours (without freezing) after preparation if protected from light. All dilutions may be stored unprotected from light under normal light conditions up to 24 hours after preparation.
If acute dystonic reactions should occur, inject 50 mg Benadryl® (diphenhydramine hydrochloride) intramuscularly, and the symptoms usually will subside.
For the Prevention of Postoperative Nausea and Vomiting
Reglan® Injection should be given intramuscularly near the end of surgery. The usual adult dose is 10 mg; however, doses of 20 mg may be used.
To Facilitate Small Bowel Intubation
If the tube has not passed the pylorus with conventional maneuvers in 10 minutes, a single dose (undiluted) may be administered slowly by the intravenous route over a 1- to 2-minute period.
The recommended single dose is:
- Pediatric patients above 14 years of age and adults — 10 mg metoclopramide base.
- Pediatric patients (6-14 years of age) — 2.5 to 5 mg metoclopramide base; (under 6 years of age) — 0.1 mg/kg metoclopramide base.
To Aid in Radiological Examinations
In patients where delayed gastric emptying interferes with radiological examination of the stomach and/or small intestine, a single dose may be administered slowly by the intravenous route over a 1- to 2-minute period.
For dosage, see intubation above.
