Medoverine (Mebeverine Hydrochloride)

Mebeverine Hydrochloride is used to manage disorders of gastrointestinal smooth‑muscle activity.

• Irritable bowel syndrome: relieves abdominal pain, cramping and irregular bowel habits.
• Functional gastrointestinal disorders: reduces spasms and improves comfort during episodes.
• Abdominal pain and cramping: eases discomfort associated with intestinal muscle contractions.

• Mebeverine Hydrochloride acts as a direct smooth‑muscle relaxant in the gastrointestinal tract, likely by inhibiting calcium influx into smooth‑muscle cells. This reduces the contractile activity of the intestinal wall without affecting normal peristalsis, thereby alleviating spasm‑related pain and discomfort.

Mebeverine Hydrochloride may cause adverse reactions, most of which are mild and reversible.

Common Side Effects

• Nausea: mild stomach upset occurring shortly after ingestion.
• Dry mouth: reduced salivation leading to a feeling of thirst.
• Headache: transient head pain of varying intensity.
• Dizziness: light‑headed sensation, especially when standing quickly.
• Abdominal discomfort: mild bloating or gas.
• Constipation: reduced bowel movements.

Serious or Rare Side Effects

• Allergic reaction: rash, itching, swelling, or angioedema.
• Severe hypotension: marked drop in blood pressure causing faintness.
• Cardiac arrhythmia: irregular heart rhythm requiring medical attention.
• Hepatic dysfunction: elevated liver enzymes indicating liver stress.
• Blood dyscrasias: abnormal blood counts such as leukopenia.
• Pancreatitis: inflammation of the pancreas presenting with severe abdominal pain.

Before prescribing Medoverine, clinicians should consider several safety measures.

• Renal or hepatic impairment: assess function and adjust use if necessary.
• Allergic history: verify no known hypersensitivity to mebeverine or excipients.
• Cardiac disease: use cautiously in patients with existing heart conditions.
• Concomitant antispasmodics: avoid additive muscle‑relaxant effects.
• Pregnancy and lactation: safety not established; weigh benefits against potential risks.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Mebeverine may interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• MAO inhibitors: risk of excessive antispasmodic effect.
• Other antispasmodics: additive smooth‑muscle relaxation may cause severe hypotension.

Moderate Interactions (Monitor Closely)

• Antidepressants (SSRIs, TCAs): may enhance gastrointestinal motility changes.
• Antihistamines: potential increase in dry‑mouth sensation.
• Calcium channel blockers: possible additive effect on smooth‑muscle tone.
• Digoxin: monitor for altered cardiac conduction.
• Warfarin: observe INR for any unexpected changes.
