Warnings and precautions

Loose motions with high fever, blood in the stool or severe abdominal pain need a doctor, not a home remedy. Oral rehydration salts and fluids matter more than any medicine when you have loose motions — dehydration is the real danger, especially in children and older people. Take a probiotic a couple of hours apart from an antibiotic so the antibiotic does not simply kill it. Do not use an anti-motility medicine such as loperamide if you have a fever or blood in the stool.

Do not take Darolac if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Probiotics are used with caution in people whose immune system is significantly suppressed.

Interactions with other medicines

Antibiotics reduce the effect of probiotics taken at the same time.

How to store Darolac Syrup

Store below 30°C in a dry place, away from direct sunlight. Some probiotic preparations ask to be refrigerated — follow the pack. Keep out of the reach of children.

Expert advice for Darolac Syrup

Keep up fluids and oral rehydration salts. Return to a normal diet as soon as you can manage it.
