Warnings and precautions

Drink plenty of water while taking any laxative, particularly the fibre-based ones — without it they can make constipation worse.

Interactions with other medicines

Laxatives can reduce the absorption of other medicines taken at the same time.

How to store Heptulac Fiber

Expert advice for Heptulac Fiber

Heptulac Fiber Oral Solution should preferably be taken at bedtime, as it requires 6 to 8 hours to show its effect. It is usually taken once a day as needed for up to 2 weeks. Take it exactly as prescribed by your doctor. Inform your doctor if you have a history of stomach disorders such as appendicitis or a bowel obstruction. Eat a fiber-rich diet (20–35 g/day) and drink 8–10 glasses of water daily to keep stools soft and regular. Exercise regularly (at least 3 times a week) to support healthy bowel movements. Do not delay bowel movements, as holding stool can worsen constipation. Do not take this medicine for several months unless specifically advised by your doctor, especially for chronic conditions. If you are using this medicine for a liver-related condition, your doctor may ask you to monitor and record the number of bowel movements per day.
