Metoclopramide (Maxolon): Essential Guide For Safe Use
Comprehensive guide to metoclopramide (Maxolon): uses, dosage, side effects, and safety information for effective nausea relief.
Metoclopramide, commonly known as Maxolon, is an antiemetic medication used to prevent and treat nausea and vomiting. It works by enhancing gastrointestinal motility, helping food move through the stomach more quickly to reduce sickness feelings. This medication is particularly useful for conditions like post-operative nausea, migraine-associated vomiting, chemotherapy-induced nausea and vomiting (CINV), and radiotherapy-induced nausea and vomiting (RINV).
About metoclopramide
| Type of medicine | Used for | Also called | Available as |
|---|---|---|---|
| Antiemetic | Nausea and vomiting | Maxolon®; Combination brands: MigraMax® (metoclopramide with aspirin) | Tablets, oral liquid medicine and injection |
Metoclopramide belongs to a group of medicines called dopamine receptor antagonists that stimulate gastrointestinal tract motility. Its mechanism of action involves parasympathetic nervous control, promoting normal peristaltic action in the upper gastrointestinal tract. This addresses conditions where disturbed motility contributes to nausea.
Key facts about metoclopramide
- Metoclopramide speeds up stomach emptying, reducing nausea from various causes including surgery, migraines, cancer treatments.
- It may cause drowsiness; avoid driving or operating machinery if affected.
- Treatment duration should not exceed 5 days to minimize risks like tardive dyskinesia.
- Not recommended for children under 1 year; limited use in adolescents.
- Available in 10mg tablets, oral solution, and injectable forms.
About nausea and vomiting
Nausea and vomiting are common symptoms triggered by the vomiting centre in the brain, activated by gastrointestinal irritation, medications, motion, or inner ear issues. Metoclopramide helps by blocking dopamine receptors and promoting gastric emptying, preventing activation of this centre.
Common causes include:
- General anaesthetics or opioid painkillers post-surgery.
- Migraine headaches.
- Chemotherapy or radiotherapy for cancer.
- Pregnancy (though caution advised).
- Other illnesses affecting the gut or balance organs.
