Motilium Tablet Uses, Dosage and Side Effects in Pakistan

What Is Motilium?

Motilium is the brand name (Janssen Pharmaceuticals) for domperidone, a dopamine D2 receptor antagonist that works in two ways:

1. Antiemetic: Blocks dopamine receptors in the chemoreceptor trigger zone (outside the blood-brain barrier), reducing nausea and the urge to vomit
2. Prokinetic: Accelerates gastric emptying and small intestinal transit — food moves through the stomach faster, reducing bloating, fullness, and reflux

Unlike metoclopramide (another antiemetic), domperidone does not easily cross the blood-brain barrier, meaning fewer CNS (brain-related) side effects.

Motilium Tablet Uses

1. Nausea and Vomiting

The primary use. Works for nausea from various causes including gastroenteritis, post-surgery, drug-induced, and travel sickness follow-up.

2. Gastroparesis

Delayed gastric emptying; food sits in the stomach too long (common in diabetic patients).

3. Bloating and Postprandial Fullness

After meals, feeling of fullness, bloating, belching, and upper abdominal discomfort.

4. GERD and Reflux Symptoms

As a prokinetic to aid gastric emptying alongside antacids/PPIs.

5. Pregnancy-Related Nausea

Used in Pakistan for morning sickness; discuss risk vs benefit with doctor.

6. Chemotherapy-Induced Nausea

For mild chemotherapy nausea (stronger options exist for severe cases).

7. Lactation Stimulation (Off-label)

Domperidone stimulates prolactin secretion, increasing breast milk production. Used off-label for insufficient milk supply.

Dosage

The Cardiac Safety Warning

In 2014–2016, regulatory agencies worldwide (EMA, MHRA, Health Canada) restricted domperidone's use due to concerns about QT interval prolongation — an abnormal heart rhythm that can cause sudden cardiac death (torsades de pointes). Key points:

• Risk is higher with doses above 10 mg per dose
• Risk is higher with chronic long-term use
• Risk is higher in those with heart disease, electrolyte abnormalities, or taking other QT-prolonging drugs
• The cardiac risk is considered low at standard doses (10 mg TDS) for short courses in otherwise healthy adults

In Pakistan, it remains freely available — but awareness of this risk is important.

Side Effects

Common:

• Dry mouth
• Headache
• Diarrhea
• Abdominal cramps

Less common (but important):

• Galactorrhea — abnormal breast milk production (in non-pregnant women and even in men) due to elevated prolactin
• Gynecomastia — breast tissue swelling in men
• Menstrual irregularities — from elevated prolactin
• QT prolongation — cardiac risk (see above)
• Extrapyramidal symptoms — rare, as it minimally crosses blood-brain barrier

Who Should NOT Take Motilium

• Existing QT prolongation or arrhythmia
• Taking other QT-prolonging drugs (azithromycin, fluoroquinolones, amiodarone, antipsychotics)
• Moderate to severe liver disease
• Prolactinoma (pituitary tumour that secretes prolactin — domperidone raises prolactin further)
• GI obstruction or perforation
• Children under 12: use with extreme caution; suspension preferred
• Pituitary tumour

Motilium and Pregnancy

The FDA has not approved domperidone in the US. In Pakistan, it is used for pregnancy nausea, but evidence is limited and the cardiac safety profile warrants caution. For mild morning sickness, ginger, vitamin B6, and small frequent meals are safe first choices. For severe vomiting in pregnancy, discuss options with your obstetrician.

Motilium for Breastfeeding (Lactation)

Domperidone increases prolactin and is used off-label to boost milk supply in breastfeeding mothers with insufficient lactation. Small amounts pass into breast milk. The cardiac concern at standard doses is considered low, but discuss with your doctor before using it while breastfeeding. Standard dose for lactation: 10 mg 3 times daily.

Drug Interactions

• QT-prolonging drugs: Azomax (azithromycin), moxifloxacin, amiodarone, haloperidol — dangerous combination
• Ketoconazole / itraconazole (antifungals): Significantly raise domperidone blood levels — avoid combination
• Erythromycin: Also raises domperidone levels — avoid
• Anticholinergics (Buscopan, antipsychotics): May reduce prokinetic effect of domperidone
• Antacids / H2 blockers: Reduce absorption — take domperidone before meals and antacids after

Pakistan Brands of Domperidone

• Motilium 10 mg (Janssen — original brand)
• Domperi
• Domezyme
• Domperidone generics
• Many pharmacy-brand domperidone 10 mg tablets

Conclusion

Motilium (domperidone 10 mg) is one of Pakistan's most widely used anti-nausea medicines, effective for nausea, vomiting, bloating, and gastroparesis. It is generally safe at standard doses (10 mg 3× daily) for short courses. However, exceeding the dose carries cardiac risks (QT prolongation), and those with heart disease or on QT-prolonging drugs should avoid it. For persistent or unexplained nausea, see a doctor — nausea can be a symptom of serious conditions. Use Ilaaj AI for an assessment from home.
