Know the basics
What is metoclopramide used for?
Metoclopramide 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.
OTHER USES: This section contains uses of metoclopramide that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use metoclopramide for a condition that is listed in this section only if it has been so prescribed by your health care professional.
Metoclopramide may also be used to prevent nausea/vomiting from chemotherapy orradiation treatments for cancer.
How should I take metoclopramide?
Take metoclopramide 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 metoclopramide, 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 metoclopramide. 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, metoclopramide 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 metoclopramide as soon as your symptoms reappear and stop when you feel better. Ask your doctor for directions for starting and stopping metoclopramide.
Take metoclopramide 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 metoclopramide 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 metoclopramide. 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.
How do I store metoclopramide?
Metoclopramide is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store metoclopramide in the bathroom or the freezer. There may be different brands of metoclopramide 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.
You should not flush metoclopramide down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.
