Constipation that has lasted for two years and requires regular use of Dulcoflex 5 mg should be assessed by a doctor. Dulcoflex contains bisacodyl, a stimulant laxative that is intended for short-term relief and is not recommended for long-term use unless advised by a healthcare professional. Your symptoms may be related to diet, low fluid intake, lack of physical activity, certain medicines, or bowel conditions that need further evaluation. Increase your intake of fibre-rich foods such as fruits, vegetables, and whole grains, drink plenty of water, and try to stay physically active. Establishing a regular time for bowel movements may also help. Your doctor may recommend tests or a different type of laxative that is more suitable for long-term use. Seek medical attention promptly if you develop severe abdominal pain, vomiting, blood in your stool, unexplained weight loss, or a sudden change in your bowel habits.
