METOCLOPRAMIDE

COMMON BRAND NAME(S): Reglan

GENERIC NAME(S): METOCLOPRAMIDE HCL

 

Description: Metoclopramide enhances the motility of the upper GI tract and increases gastric emptying without affecting gastric, biliary or pancreatic secretions. It increases duodenal peristalsis which decreases intestinal transit time, and increases lower oesophageal sphincter tone. It is also a potent central dopamine-receptor antagonist and may also have serotonin-receptor (5-HT3) antagonist properties.

Pharmacokinetics:

Absorption: Rapidly and almost completely absorbed from the GI tract (oral); peak plasma concentrations after 1-2 hr.

Distribution: Widely distributed; crosses the blood-brain barrier and placenta; enters breast milk.

Metabolism: Extensively hepatic.

Excretion: Via urine (as unchanged drug, sulfate or glucuronide conjugates and metabolites), faeces; 4-6 hr (terminal elimination half-life).

Uses

This medication is used to treat certain conditions of the stomach and intestines. Metoclopramide is used as a short-term treatment (4 to 12 weeks) for persistent heartburn when the usual medicines do not work well enough. It is used mostly for heartburn that occurs after a meal or during the daytime. Treating persistent heartburn can decrease the damage done by stomach acid to the swallowing tube (esophagus) and help healing.

Metoclopramide is also used in diabetic patients who have poor emptying of their stomachs (gastroparesis). Treating gastroparesis can decrease symptoms of nausea, vomiting, and stomach/abdominal fullness. Metoclopramide works by blocking a natural substance (dopamine). It speeds up stomach emptying and movement of the upper intestines.

This drug is not recommended for use in children younger than 1 year due to an increased risk of serious side effects (such as muscle spasms/uncontrolled muscle movements). Ask the doctor or pharmacist for details.

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This drug may also be used to prevent nausea/vomiting from chemotherapy or radiation treatments for cancer.

How to use metoclopramide

See also Warning section.

Read the Medication Guide provided by your pharmacist before you start taking metoclopramide and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

Take this medication by mouth 30 minutes before meals and at bedtime, usually 4 times daily or exactly as directed by your doctor. If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

If you are using the disintegrating tablet, do not remove the tablet from the blister pack until right before your dose. Dry your hands before using this medication. Do not use the tablet if it is broken or crumbled. Immediately after removing the tablet, place it on the tongue. Allow it to dissolve completely, then swallow it with saliva. You do not need to take this product with water.

Dosage is based on your weight, medical condition, and response to treatment. If heartburn only occurs at certain times (such as after the evening meal), your doctor may direct you to take a single dose before those times instead of taking it throughout the day. This will reduce your risk of side effects.

Because of the risk of tardive dyskinesia, do not take this more often, in larger doses, or for longer than directed by your doctor. According to the manufacturer, treatment should not exceed 12 weeks.

To treat diabetic gastroparesis, this medication is usually taken for 2 to 8 weeks until your gut is working well. This condition may recur from time to time. Your doctor may direct you to start taking this medication as soon as your symptoms reappear and stop when you feel better. Ask your doctor for directions for starting and stopping this medication.

Take this medication regularly as directed to get the most benefit from it. To help you remember, take it at the same times before a meal each day.

If this medication has been used regularly for a long time or in high doses, withdrawal symptoms (such as dizziness, nervousness, headaches) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately.

Tell your doctor if your condition persists or worsens.

Warnings

This medication may cause a serious movement disorder called tardive dyskinesia. In some cases, this condition may be permanent. The risk of tardive dyskinesia is increased with the longer use of the medication and the more medication that you take. The risk is also increased in older adults (especially women) and in people with diabetes. Do not use metoclopramide for longer than 12 weeks. Talk to your doctor about the risks and benefits of this medication. In rare cases, some patients may need to use this medication longer than 12 weeks.

Tell your doctor right away if you develop any unusual uncontrolled movements (especially of the face, mouth, tongue, arms or legs). There is no treatment for tardive dyskinesia, but in some cases the symptoms may lessen or stop once metoclopramide is stopped.

Side effects

Drowsiness, dizziness, tiredness, trouble sleeping, agitation, headache, and diarrhea may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: mental/mood changes (such as anxiety, confusion, depression, thoughts of suicide), decreased sexual ability, inability to keep still/need to pace, muscle spasms/uncontrolled muscle movements (such as twisting neck, arching back), Parkinson-like symptoms (such as shaking, slowed/difficult movement, mask-like facial expression), abnormal breast-milk production, enlarged/tender breasts, swelling of the hands/feet, changes in menstruation in women.

This medication may rarely cause a very serious condition called neuroleptic malignant syndrome (NMS). Get medical help right away if you have any of the following symptoms: fever, muscle stiffness, severe confusion, sweating, fast/irregular heartbeat.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
