Benerva 50mg tablets are vitamin tablets which contain thiamine (vitamin B1). They are used to treat thiamine deficiency (when your body does not have enough of the vitamin).

Even though thiamine is found naturally in many foods (especially in yeast, wholegrain cereals, meats and beans), sometimes your body requires a supplement. This may be because your diet does not contain enough thiamine or you may not be absorbing it from your diet effectively. You may also have a special need for extra thiamine, especially if you are excreting it quickly from your body (e.g. in your urine).

By taking Benerva 50mg tablets, you can make sure you have sufficient thiamine in your diet.


DO NOT take Benerva 50mg tablets if you are:

•    Allergic (hypersensitive) to thiamine or any of the other ingredients in the product (see section 6, Further Information).

•    Under 12 years of age.

Important information about some of the ingredients:

Taking other medicines:

Tell your doctor or pharmacist if you are taking any other medicines, including those obtained without a prescription, such as vitamins or herbal preparations which you have bought yourself.

Certain medicines can reduce the effect of your thiamine tablets.

Tell your doctor if you are taking the following medicine because he/she may need to adjust your thiamine dose:

•    fluorouracil (used to treat certain cancers and viral infections).

Having blood tests or other medical tests:

High concentrations of thiamine in the blood can affect certain medical tests. If you are having a blood test, scan, or any other medical test, tell your doctor that you are taking thiamine tablets.
