Hyoscine Butylbromide Ria Generics (Hyoscine Butylbromide)

Hyoscine Butylbromide is used to manage gastrointestinal and genitourinary smooth‑muscle spasm.

• Abdominal cramps: reduces intensity of cramp pain by relaxing intestinal smooth muscle.
• Irritable bowel syndrome: eases bowel spasm and associated discomfort.
• Biliary colic: alleviates gall‑bladder related muscle contraction.
• Renal colic: diminishes ureteral spasm during kidney stone passage.
• Menstrual pain: lessens uterine muscle cramps during menstruation.

• Hyoscine Butylbromide acts as a competitive antagonist at muscarinic acetylcholine receptors in smooth muscle. By blocking these receptors, it inhibits parasympathetic stimulation, leading to reduced intracellular calcium and relaxation of smooth muscle in the gastrointestinal, biliary, urinary and uterine tracts, thereby decreasing spasm and associated pain.

Hyoscine Butylbromide may cause several adverse reactions, ranging from mild to serious.

Common Side Effects

• Dry mouth: reduced salivary secretion.
• Blurred vision: difficulty focusing due to pupil dilation.
• Constipation: slowed intestinal motility.
• Urinary retention: difficulty emptying the bladder.
• Tachycardia: increased heart rate.
• Dizziness: light‑headed sensation.

Serious or Rare Side Effects

• Allergic reactions: rash, itching, swelling.
• Severe skin rash: Stevens‑Johnson‑like manifestations.
• Anaphylaxis: life‑threatening hypersensitivity.
• Acute glaucoma: sudden increase in intra‑ocular pressure.
• Severe constipation: bowel obstruction risk.
• Difficulty swallowing: dysphagia due to esophageal spasm.

Before using Hyoscine Butylbromide, consider the following precautions.

• Glaucoma assessment: anticholinergic effect may worsen intra‑ocular pressure.
• Urinary retention: avoid in patients with existing bladder outflow obstruction.
• Elderly patients: increased sensitivity to anticholinergic side effects.
• Renal/hepatic impairment: monitor and adjust use as needed.
• Pregnancy and breastfeeding: safety not established; consult a physician.
• Store at room temperature: keep in the original pack, protect from moisture.

Hyoscine Butylbromide can interact with other medicines, requiring attention.

Major Interactions (Avoid)

• Other anticholinergic agents: additive anticholinergic burden.
• Tricyclic antidepressants: increased risk of dry mouth and constipation.
• Antihistamines: heightened dryness and sedation.

Moderate Interactions (Monitor Closely)

• Beta‑blockers: may mask tachycardia caused by anticholinergic effect.
• Alcohol: can amplify dizziness and central nervous system effects.
