Hyospasmol is a widely used medication in South Africa, primarily indicated for the management of stomach and bladder cramps. It is commonly prescribed for conditions such as irritable bowel syndrome (IBS) and other gastrointestinal or genitourinary disorders characterized by spasms and pain. This guide provides detailed information on its uses, side effects, precautions, and other essential aspects .
1.What is Hyospasmol?
Hyospasmol is a medication containing hyoscine butylbromide, a compound that belongs to the antispasmodic drug class. It works by relaxing the smooth muscles of the gastrointestinal and urinary tracts, thereby relieving pain and discomfort caused by spasms.
1.2. Forms and Availability
Hyospasmol is available in different forms, including:
- Tablets (commonly 10 mg per tablet)
- Injectable solutions for severe cases requiring immediate relief
In South Africa, Hyospasmol is available over-the-counter (OTC) for mild symptoms but may also be prescribed by healthcare providers for specific conditions.
2. Uses of Hyospasmol
2.1. Primary Indications
Hyospasmol is used for the treatment of:
- Stomach cramps: Often associated with IBS, indigestion, or other gastrointestinal disorders.
- Bladder cramps: Conditions like overactive bladder syndrome or urinary tract infections (UTIs).
- Menstrual pain: Relieves uterine spasms during menstruation.
2.2. Secondary Uses
While not its primary use, Hyospasmol may also be prescribed for:
- Spasms in the bile ducts or urinary tract.
- Pain relief following minor abdominal surgeries.
- Conditions like renal colic or dysmenorrhea (severe menstrual pain).
3. Mechanism of Action

Hyospasmol contains hyoscine butylbromide, which blocks muscarinic receptors in smooth muscles. This action reduces involuntary contractions, alleviating pain and improving comfort. Unlike central anticholinergic agents, Hyospasmol acts peripherally, meaning it has minimal effects on the brain and central nervous system.
4. Dosage and Administration
4.1. Recommended Dosage
- Adults: Typically, 1-2 tablets (10-20 mg) up to 4 times a day.
- Children: Dosage varies based on age and weight; consult a pediatrician.
4.2. Administration Guidelines

- It can be taken with or without food.
- Do not crush or chew tablets; swallow them whole.

If you miss a dose, take it as soon as you remember. If it is close to your next dose, skip the missed one and resume your regular schedule. Avoid doubling up doses.
