Metoclopramide - oral

Patient Medicine Information
Why do I need this medicine?
Metoclopramide helps to prevent and relieve nausea and vomiting.

This medicine is also used to relieve reflux disease (also known as "heartburn", in which food or acid from your stomach backs up into your mouth, leaving a sour or bitter taste).

It may also be used to treat the symptoms of slow stomach emptying (gastric stasis) in patients with diabetes.

Metoclopramide may be used to treat other conditions as decided by your doctor.
How do I take this medicine?
Take Metoclopramide exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.

Take this medicine on an empty stomach at least half an hour before meals.

Metoclopramide is available as a tablet, orodispersible tablet or oral liquid.

If you are taking an oral suspension, shake the bottle well before you take it to ensure that the liquid is evenly mixed. Use the measuring spoon or cup provided to measure your dose.

If you are taking the orodispersible tablet:
  1. Remove it from the foil only just before you take it. Do not leave the orodispersible tablet exposed to air. Do not push the orodispersible tablet through the foil as it is fragile and easily broken.
  2. Remove the orodispersible tablet with dry hands by peeling the backing off the foil and tipping the tablet onto your dry hands.
  3. Place the orodispersible tablet directly on your tongue as soon as it is taken out of the foil. The orodispersible tablet will immediately start to melt on the tongue. It can then be swallowed with or without water.
Do not cut, break or crush the orodispersible tablets.

If you are taking an oral solution, use the measuring syringe, spoon or cup provided to measure out your prescribed dose.
What should I do if I have forgotten to take this medicine?
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.

DO NOT double a dose under any circumstances.

If you often forget to take your medicine, let your doctor and pharmacist know.

Inform your doctor if you have an inherited condition known as G6PD deficiency.

A certain enzyme called CYP2D6 is involved in the breakdown of Metoclopramide in the body. Individuals who are poor metabolisers of CYP2D6 may have increased exposure to metoclopramide, resulting to increased risk of adverse effects including involuntary muscle movements. Although not routinely done, your doctor may advise you to take genetic testing to check if this medicine is best suited for you. If you know you have this gene type, inform your doctor.

For as long as you are taking this medicine, you may need to have regular blood tests to check your body’s response to the medicine. Your doctor will advise you about how often you need to have blood tests. Regular monitoring of signs of involuntary body movements and altered mental status may also be needed.
