Cen-E (Generic)

This supplement is used to prevent or treat a lack of vitamin E in the body. A low body level of vitamin E is rare. Most people who eat a normal diet do not need extra vitamin E. However, vitamin E supplements are used in premature newborns and in people who have problems absorbing enough vitamin E from their diets. Vitamin E is important in protecting your body's cells from damage. It is known as an antioxidant.

Take this product by mouth as directed. Follow all directions on the product package. If you have any questions, ask your doctor or pharmacist.

If you are using a liquid form of this product, carefully measure your dose using a medication-measuring device or spoon. Do not use a household spoon because you may not get the correct dose. If your liquid form is a suspension, shake the bottle well before each dose.

Dosage is based on your medical condition and response to treatment. Do not increase your dose or take it more often than recommended. Taking too much vitamin E may increase your risk of side effects.

High doses of vitamin E (400 units or more per day) may increase the chance of rare but very serious side effects. There is no proof that high doses of vitamin E help to prevent or treat heart disease. There is very little evidence that it helps prevent or treat Alzheimer's disease. In some people, taking these high doses may even be harmful. Talk to your doctor or pharmacist and discuss the risks and benefits before taking vitamin E supplements.

If your doctor prescribes this product for vitamin E deficiency, use it regularly to get the most benefit from it. To help you remember, take it at the same time each day. You should see improvement of symptoms such as numbness/tingling of the hands/feet and weakness. If your condition persists or worsens, or if you think you may have a serious medical problem, seek immediate medical attention.
