Fewash 1.2% Liquid is a type of sugar used to treat constipation. This medicine works by drawing water into the intestine through osmosis, which makes the stool soft and easier to pass. Fewash 1.2% Liquid should be taken as advised by your doctor. It may be taken with or without food. Use this medicine regularly to get the most 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. Fewash 1.2% Liquid takes at least 48 hours to work. Talk to your doctor if you are still constipated after three days. The most common side effects are nausea, vomiting, and stomach cramp. These are usually mild and go away after a couple of days. You can help reduce the side effects by drinking plenty of fluids and by taking the medicine between meals. Occasionally people develop serious side effects including severe stomach pain, severe diarrhea, mood changes, and seizures. Talk to your doctor straight away if you notice any of these. Before taking Fewash 1.2% Liquid, 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.
