Understanding the purpose of Meva SR capsules
Meva SR capsules contain mebeverine hydrochloride, a type of antispasmodic medication. It is prescribed to treat the symptoms of Irritable Bowel Syndrome (IBS), which include abdominal pain, cramps, bloating, gas, and changes in bowel habits. Mebeverine works by acting directly on the smooth muscle of the intestines, without affecting normal gut motility, to provide relief from painful spasms. Although it is generally well-tolerated, some individuals may experience adverse effects.
Common and less serious side effects
For most users, Meva SR has a good safety profile, and any side effects are usually mild and temporary. Common and less serious reactions reported include:
- Gastrointestinal Discomfort: Nausea, indigestion, heartburn, or even constipation can occur.
- Central Nervous System Effects: Some individuals may experience headaches, dizziness, or lightheadedness. Dizziness is a notable effect that should be considered if driving or operating machinery.
- Fatigue: Occasional tiredness or fatigue has been reported, though this is also a known symptom of IBS.
- Insomnia: Rarely, difficulty sleeping can be an adverse effect.
- Mild Skin Reactions: Mild allergic skin reactions, such as a rash or itchiness, may occur.
Rare but serious side effects
While uncommon, more serious side effects can develop. These usually involve severe allergic reactions and require immediate medical attention.
- Severe allergic reactions (Anaphylaxis): Signs include extensive skin rashes, swelling of the face, lips, or tongue, and difficulty breathing or swallowing. This is a medical emergency.
- Angioedema: Swelling of the deeper layers of the skin, which is a specific type of serious allergic reaction.
- Porphyria: Mebeverine is contraindicated in patients with acute porphyria, a genetic disorder affecting the nervous system, as it can worsen the condition.
Comparison of Meva SR (mebeverine) and Dicyclomine
Both mebeverine and dicyclomine are antispasmodic medications used for treating IBS, but they have different mechanisms and side effect profiles.
| Feature | Meva SR (Mebeverine) | Dicyclomine |
|---|---|---|
| Mechanism | Acts directly on smooth muscle in the gut. | Acts as an anticholinergic, blocking muscarinic receptors. |
| Common Side Effects | Headache, dizziness, nausea, mild skin reactions. | Dry mouth, constipation, blurred vision. |
| Anticholinergic Side Effects | Minimal, as it does not have significant systemic anticholinergic effects. | Common, due to its anticholinergic mechanism. |
| Sleep Disturbances | Insomnia or tiredness are reported, but rare. | Can cause drowsiness. |
| Use in Glaucoma | Rare risk of inducing angle-closure glaucoma. | Use with caution, as it can worsen symptoms of glaucoma. |
Important precautions before use
Consulting a doctor is vital before starting Meva SR, especially if you have existing health conditions or are taking other medications.
- Pre-existing Conditions: Inform your doctor if you have kidney, liver, or heart problems.
- Hypersensitivity: The drug is contraindicated in people with a known hypersensitivity to mebeverine.
- Pregnancy and Breastfeeding: Meva SR is not recommended for pregnant or breastfeeding women due to limited safety data. A doctor must evaluate potential risks and benefits.
- Drug Interactions: Inform your doctor about all prescription and non-prescription medications, including herbal supplements, to avoid adverse interactions.

Conclusion
While Meva SR capsules are an effective treatment for IBS symptoms, it is important to be aware of the potential side effects. Common side effects are generally mild and temporary, but patients should be alert for signs of a rare, severe allergic reaction and seek medical help if it occurs. Always take the medication as directed by a healthcare provider and discuss any concerns or pre-existing conditions with them. Following a doctor's guidance, and incorporating lifestyle changes, is key to managing IBS symptoms safely.
