Senokot 7.5mg Tablets are a stimulant laxative containing naturally derived senna for the short-term relief of occasional constipation. Senna stimulates the muscles of the bowel, helping move stools through the intestine. The manufacturer states Senokot typically works within 8–12 hours, making bedtime dosing convenient for morning relief.
This 500-tablet pack is a pharmacy-only presentation. Irish product licence: PA0979/016/002. Licence holder: Reckitt Benckiser Ireland Ltd.

Important Information
Do not take Senokot if you have an intestinal obstruction or narrowing, bowel atony, symptoms of appendicitis, inflammatory bowel disease (such as Crohn’s disease or ulcerative colitis), severe dehydration, or if you have already taken another laxative and remain constipated.
Seek professional advice if you experience unexplained abdominal pain, nausea or vomiting, rectal bleeding, blood in the stool, or a sudden change in bowel habits lasting more than two weeks.
Long-term or excessive stimulant-laxative use should be avoided as it can cause fluid and electrolyte disturbances and interfere with normal bowel function. Senokot does not reduce calorie absorption and should not be used for weight loss.
