The active ingredient is Modafinil. Modafinil can be taken by adults who suffer from narcolepsy to help them to stay awake. Narcolepsy is a condition that causes excessive daytime sleepiness and a tendency to fall asleep suddenly in inappropriate situations (sleep attacks). Modafinil may improve your narcolepsy and reduce the likelihood that you will have sleep attacks but there may still be other ways that you can improve your condition and your doctor will advise you.
Always take Modafinil Tablets exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure. Tablets should be swallowed whole with water.
Adults: The usual dose is 200mg a day. This can be taken once daily (in the morning) or divided into two doses a day (100mg in the morning and 100mg at midday). Your doctor in some cases may decide to increase your daily dose up to 400mg.
Elderly patients (over 65 years of age): The usual dose is 100mg a day.
Your doctor will only increase your dose (up to the maximum 400mg a day) provided that you do not have any liver or kidney problems.
Adults with severe kidney and liver problems: The usual dose is 100mg a day.
Your doctor will review your treatment regularly to check that it is right for you.
If you take more Modafinil Tablets than you should : if you take too many tablets you may feel sick, restless, disorientated, confused, agitated, anxious or excited. You may also have difficulty sleeping, diarrhoea, hallucinations (sensing things that are not real), chest pain, a change in the speed of your heartbeat or an increase in blood pressure.
