Talk to your doctor straight away if you notice any of these. Before taking this medicine, tell your doctor if you have diabetes or if you are unable to digest milk sugar (lactose intolerant). If you are taking this medicine for the long term, your doctor may recommend occasional blood tests to check your mineral levels (e.g., potassium and sodium).

Benefits of Purolac Syrup
In Constipation
Constipation occurs when bowel movements become less frequent, and stools are hard to pass. Purolac Syrup helps soften the stool and increases bowel movement frequency by drawing water into the intestines. This provides gentle and effective relief from constipation and improves digestive comfort.
In Treatment of Hepatic encephalopathy
Hepatic encephalopathy is a liver-related condition that affects brain function due to the buildup of toxins in the blood. Purolac Syrup helps remove these toxins, especially ammonia, through bowel movements. This helps improve mental clarity, reduces confusion, and supports better liver health and overall well-being.

In some cases, it may also be prescribed for certain liver-related conditions where reducing blood ammonia levels is required. Your doctor will decide the appropriate use based on your condition.
Is it safe to use Purolac Syrup if I have diabetes?
Purolac Syrup contains small amounts of sugars such as lactose and galactose. These sugars are absorbed in small amounts, but they may affect blood glucose levels if taken in high doses or for a long time. If you have diabetes, inform your doctor before starting this medicine. Your blood sugar may need to be monitored during treatment.
Does Purolac Syrup cause gas or abdominal bloating?
Gas, bloating, and mild stomach cramps are common, especially during the first few days of treatment. These effects occur because gut bacteria break down the sugars in the medicine, which can produce gas. These symptoms often improve with continued use. Consult your doctor if the discomfort becomes severe or persistent.
Is Purolac Syrup safe for patients with lactose intolerance?
Purolac Syrup contains small amounts of lactose. People with lactose intolerance may experience gas, bloating, or stomach cramps after taking it. If you are sensitive to dairy products, inform your doctor before starting this medicine. They can decide whether this option is suitable for you.
Does Purolac Syrup help with acidity or gas?
No, Purolac Syrup is not an antacid. It is used to relieve constipation by promoting bowel movements. It may actually increase gas during the initial days of use. If you have symptoms such as heartburn or reflux, talk to your doctor about appropriate treatment options.
