Thiamine - Vitamin B1

About thiamine

Thiamine is a type of vitamin B. Several different substances belong to the group of vitamins known as the B vitamins. Thiamine is known as vitamin B₁.

Foods that are good natural sources of thiamine are cereals, nuts, peas, beans and pork. Although thiamine deficiency tends to be rare in the UK, your doctor may recommend that you take a supplement of thiamine if for some reason you cannot get sufficient vitamin B₁ from your normal diet.

Thiamine is also an ingredient of a number of multiple-vitamin preparations that are available to buy without a prescription.

To make sure that this is the right treatment for you, before you start taking thiamine it is important that you speak with a doctor or pharmacist:

• إذا كنت حاملاً أو مرضعة. وذلك لأنك أثناء الحمل أو الرضاعة يجب أن تتناولي الأدوية فقط بناءً على توصية الطبيب.

• إذا كنت قد تعرضت في أي وقت مضى لرد فعل تحسسي تجاه دواء.

• Before you start taking thiamine, read the manufacturer's printed information leaflet from inside the pack.

• Thiamine tablets are usually taken once a day. Doses of 25-100 mg are sufficient to prevent mild deficiency. You can take the tablets at whatever time of day you find easiest to remember, either before or after meals. If you have been prescribed a higher dose (200-300 mg daily), your doctor will recommend that you take this as one tablet (100 mg) two or three times a day.

• Do not take more than the dose which has been recommended or prescribed.

• It is likely that your doctor will give you some lifestyle and dietary advice. It is important you follow any recommendations you are given about eating a well-balanced diet and not drinking alcohol.

Thiamine is unlikely to cause any side-effects at the recommended doses. If, however, you experience any symptoms which you think may be due to the tablets, please speak with your doctor or pharmacist for further advice.

• احفظ جميع الأدوية بعيدًا عن متناول ورؤية الأطفال.
