Alverine Capsules: Uses, Dosage, Side Effects And Safety
Relief from IBS cramps, bloating, and abdominal pain with alverine capsules (Audmonal, Spasmonal).
Alverine is an antispasmodic medicine which relaxes smooth muscles in the gut and uterus to relieve bloating and crampy pain in the lower abdomen. It is primarily used for irritable bowel syndrome (IBS) and diverticular disease, and can also ease period pain.
About alverine capsules
Alverine citrate acts directly on the smooth muscle in the gastrointestinal tract and uterus, causing relaxation to prevent painful spasms. Smooth muscle is involuntary muscle found in organs like the intestines and womb—not under conscious control. By inhibiting contractions, alverine reduces symptoms such as abdominal pain, bloating, constipation, and diarrhea associated with IBS and similar disorders.
In IBS, normal gut muscle activity is disrupted, leading to spasms. Diverticular disease involves inflamed pouches in the gut lining that trap food particles, causing pain. Alverine eases these by relaxing the muscle wall. It is also effective for dysmenorrhea (painful periods) due to uterine spasms.
Capsules are available in two strengths: 60 mg (standard, e.g., Audmonal, Spasmonal) and 120 mg (Forte for severe symptoms, e.g., Audmonal Forte). They come as prescription or over-the-counter (after doctor diagnosis).
