Colimex Suspension is used for reducing stomach pain due to spasms, cramps and bloating. It contains Dicyclomine and Simethicone, primarily taken to relieve period pain, spasmodic abdominal pain, bloating, and general pain-related discomfort of the lower abdomen. It reduces spasms and pain by relaxing the muscles and blocking certain chemical messengers in the brain responsible for causing the sensation of pain. Also, it treats bloating and releases stomach gas more efficiently. Thus, it helps reduce muscle contractions and pain by acting on the intestine's inner lining, allowing gas bubbles to come together, relieving cramps and spasms. It may cause some common side effects such as dryness in the mouth, dizziness, weakness, nervousness, sleepiness, and nausea.
