Product introduction

Duphalac Oral Solution Lemon can be taken with or without food. You should take this medicine as advised by your doctor. Use this medicine regularly to get the maximum benefit and try to take it at the same time(s) each day. Your dose may go up or down depending on how well it is working. Do not take more than you are advised to and, if you miss a dose, do not take an extra one to make up for it. This medicine takes at least 48 hours to work. Talk to your doctor if you are still constipated after 3 days.

The most common side effects are nausea and vomiting. These are usually mild and go away after a couple of days. Occasionally people develop serious side effects including severe diarrhea and electrolyte imbalance. Talk to your doctor straight away if you notice any of these.

Before taking this medicine, you should tell your doctor if you have diabetes or if you are unable to digest milk sugar (lactose intolerant). If you use this medicine over a long period of time, your doctor may want you to have occasional blood tests to check the mineral levels (e.g. potassium and sodium). Do not take other laxative medicines while taking this medicine and check with your doctor if you are pregnant or breastfeeding.

Uses of Duphalac Oral Solution

Benefits of Duphalac Oral Solution

Constipation
Constipation occurs when bowel movements become less frequent and stools are hard to pass. Duphalac Oral Solution Lemon 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.

Treatment of Hepatic encephalopathy
Hepatic encephalopathy is a liver-related condition that affects brain function due to the buildup of toxins in the blood. Duphalac Oral Solution Lemon 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.
