Ibs Relief (Mebeverine Hydrochloride)

• Mebeverine is used to manage functional gastrointestinal disorders that involve smooth‑muscle spasm.
• Irritable bowel syndrome: reduces abdominal pain, cramping and urgency associated with the condition.
• Functional bowel disorders: improves bowel habit regularity and lessens discomfort.
• Spastic colon: alleviates colonic spasms and related abdominal distress.

• Mebeverine acts directly on gastrointestinal smooth muscle by inhibiting calcium influx through voltage‑dependent calcium channels. This blockade reduces intracellular calcium concentration, leading to relaxation of the muscle wall and attenuation of spasm. By stabilizing the smooth‑muscle tone, it helps normalize transit and reduces pain signals.

Mebeverine may be associated with a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Nausea: mild stomach upset that usually resolves without medical intervention.
• Dry mouth: reduced salivation leading to a feeling of thirst and difficulty swallowing.
• Headache: transient head discomfort that may improve with rest or simple analgesics.
• Dizziness: light‑headed sensation, especially upon standing, that is generally short‑lived.

Serious or Rare Side Effects

• Allergic reaction: rash, itching, swelling of the face or throat, or anaphylaxis requiring immediate medical attention.
• Severe hypotension: marked drop in blood pressure causing faintness, dizziness and possible syncope.

When prescribing or dispensing Mebeverine, several precautionary measures should be observed to ensure safe use.

• Assess renal and hepatic function: evaluate before initiating therapy in patients with liver or kidney impairment.
• Use with caution in the elderly: age‑related sensitivity may increase risk of dizziness or hypotension.
• Avoid in known hypersensitivity: discontinue if allergic reactions such as rash or swelling occur.
• Monitor for cardiac symptoms: patients with pre‑existing heart disease should be observed for arrhythmia or blood pressure changes.
• Review concomitant anticholinergic load: concurrent anticholinergic drugs may enhance dry‑mouth or constipation.
• Store at ambient temperature: keep below 25°C in the original packaging, protected from moisture and direct sunlight.

Mebeverine can interact with other medicines; awareness of significant interactions helps prevent adverse outcomes.

Major Interactions (Avoid)

• Strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin): may increase Mebeverine plasma levels and risk of toxicity.
• MAO inhibitors: concurrent use can potentiate anticholinergic effects and should be avoided.

Moderate Interactions (Monitor Closely)

• Other antispasmodics (e.g., dicyclomine): additive smooth‑muscle relaxation may enhance side‑effects.
• Antihistamines with anticholinergic properties: may increase dry‑mouth and constipation.
• Digoxin: altered gastrointestinal motility could affect absorption; monitor therapeutic levels.
