Metoclopramide is an anti-emetic medication that helps to reduce the risk of nausea and vomiting in certain conditions. The active ingredient in this drug influences the way that the vomiting centre of the brain works, impacting the reactions of the stomach.
What is metoclopramide?
Metoclopramide is a prescription-only drug that comes in both branded and non-branded versions. It is available in a range of different forms, including tablets, capsules and an oral solution. In rare cases, metoclopramide may be given in intravenous form, though this will only be possible in hospital situations.
Metoclopramide belongs to a group of drugs called prokinetics and anti-emetics, designed to reduce your risk of vomiting and nausea as well as helping you to empty the contents of your stomach when necessary to reduce acid. These drugs work by emptying the contents of your stomach through your intestines, speeding up muscle contractions. At the same time, the tightness of your lower oesophageal sphincter is increased, which means that stomach acid cannot flow back into the oesophagus. Metoclopramide also prevents nausea and vomiting by blocking the receptors in the human body that often cause nausea and vomiting.
When is metoclopramide used?
Metoclopramide can be used to treat a range of conditions associated with the intestines and stomach and is often a short- term treatment option for heartburn when other medicines do not work properly. It is usually used for heartburn instances that occur during the day or after a meal. Treating persistent acid reflux can reduce the amount of damage done to the oesophagus by stomach acid.
Metoclopramide can also be used in patients with diabetes who usually have problems emptying their stomach. Treating this condition can help to reduce symptoms of vomiting and nausea, and reduce abdominal fullness. Metoclopramide works by blocking dopamine in the body and speeding the movement of the upper intestines. This medication should not usually be given to children because the risk of muscle spasms and other side effects will often be greater.
How do you use metoclopramide?
Metoclopramide comes with a patient leaflet to be read carefully before the start of treatment. You should speak to a doctor or pharmacist if you have any questions on how to take this substance. Take the medication by mouth up to 30 minutes before meals and at bedtime when told to do so by your doctor. Follow your doctor’s instructions carefully.
If you are taking the suspension form, you will need to measure it using the device that is provided as a household spoon will not give you the correct dose. If you are using the disintegrating tablet, you should not remove the tablet from the packaging before you are ready to take your dose. Do not use the tablet if it is broken.
If heartburn only occurs at certain times, your doctor might tell you to take your dose at those times rather than using it constantly throughout the day. This could reduce your risk of side effects. Take this medication regularly to get the best benefit from it. To help you take it consistently, it is best to use the medication at the same time each day.
If you suddenly stop taking this medication, you might suffer from withdrawal symptoms such as headaches, nervousness and dizziness. To help prevent this, your doctor is likely to reduce your dose gradually.
What dosages are there?
Metoclopramide will be given to you in a dose based on your medical condition. Response to treatment and age will also be taken into account. Because of the higher risk of various side effects, it is not a good idea to take this medication more often than necessary. Treatment is usually for maximum of five days.
The most common dosage is metoclopramide tablets of 10 mg that are taken one to three times every day, after a bout of acid reflux begins. However, your treatment will depend on your condition.

Take this medication exactly as directed to get the most benefit from it. Tell your doctor if you feel that your conditions are persisting or getting worse when you are taking metoclopramide.
