Product introduction

Nulactol Syrup should be taken as advised by your doctor. It may be taken with or without food. You should take the amount your doctor's advice, and you can mix it with water or fruit juice if you prefer. 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’s working. Don’t take more than you’re advised to and, if you miss a dose, don’t take an extra one to make up for it. Nulactol Syrup takes at least 48 hours to work. Talk to your doctor if you’re still constipated after three days.

The most common side effects are nausea and vomiting. These are usually mild and go away after a couple of days. You may also feel (or be) sick. You can help avoid the side effects by drinking plenty of fluids, taking your 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 Nulactol Syrup, you should tell your doctor if you have diabetes or if you’re 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). Don’t take other laxative medicines while taking this medicine and check with your doctor if you’re pregnant or breastfeeding.
