What B-Dose Forte Injection is used for
B-Dose Forte 2.5mL Injection contains the Vitamins B1, B2, B3, B5, B6 and B12 as the following active ingredients:
- B1 - Thiamine hydrochloride,
- B2 - Riboflavine sodium phosphate,
- B3 - Nicotinamide,
- B5 - Dexpanthenol,
- B6 - Pyridoxine hydrochloride,
- B12 - Cyanocobalamin.
These B vitamins are required by the body for normal metabolic processes in your cells, including the production of energy. Different metabolic processes need several of these B vitamins at the same time. Deficiencies of one, some or all of these vitamins in your cells can have serious consequences for your health.
Vitamin B deficiencies:
Vitamin B deficiencies may occur as a result of a diet deficient in B vitamins, malnutrition, or changes to the gastrointestinal tract which slow or prevent the absorption of B vitamins (e.g. abdominal surgery or some diseases of the gastrointestinal tract).
A specific deficiency of vitamin B1 (thiamine) may cause the disease beriberi.
A specific deficiency of vitamin B3 (niacin) may cause the disease pellagra.
A specific deficiency of vitamin B12 (cobalamin) may cause the disease pernicious anaemia.
Some of the B vitamins need other B vitamins to work properly.
Your doctor may prescribe B-Dose Forte Injection to treat specific vitamin B deficiencies, or to raise the levels of B vitamins in your body.
When administration by mouth is not feasible or appropriate:
Your doctor may decide that B-Dose Forte Injection is the best way for you to take B vitamins.
Debilitated or elderly patients where the diet is inadequate:
Confinement to bed, debility or old age may lead to an inadequate diet. In these cases, vitamin B deficiencies may occur.
Your doctor may prescribe B-Dose Forte to supplement B vitamins missing in your diet.
Malnutrition resulting from alcoholism:
Alcoholism can lead to a diet deficient in B vitamins. The normal metabolism of alcohol in your liver also requires B vitamins, especially thiamine. Thiamine may be prescribed to treat Wernicke’s encephalopathy, a disorder caused by thiamine deficiency in alcoholism.
B-Dose Forte Injection contains a high dose of thiamine and may be prescribed by your doctor to help the effects of alcoholism.
Peripheral neuritis and Carpal tunnel syndrome:
This means nerve pain, usually in the arms or hands, legs or feet (the peripheral parts). Many of the B vitamins are important for the normal functioning of the nervous system. Long-term alcoholism, beriberi, pellagra or long-term gastrointestinal disease may lead to B vitamin deficiencies and peripheral nerve pain.
Carpal tunnel syndrome and its symptoms may be relieved by the administration of vitamin B6 (pyridoxine). Carpal tunnel syndrome symptoms include pain in the hands and wrists, weakness of the hands and loss of grip strength, and coldness of the hands and fingers.
Your doctor may prescribe B-Dose Forte Injection to treat peripheral nerve pain or carpal tunnel syndrome.
Anaemia occurs when red blood cells cannot carry sufficient oxygen to meet the requirements of the body’s cells. This may be due to a deficiency of oxygen, lack of ability of red blood cells to bind oxygen, or some defect of red blood cells. Vitamin B12 is needed to make red blood cells grow correctly, without it the red blood cells become large and less effective. This is a type of anaemia called megaloblastic (large cells) anaemia. Megaloblastic anaemia may also be caused by a folate (folic acid) deficiency. The “pernicious” part is because prolonged Vitamin B12 deficit can also lead to damage to the nervous system. The combination of nervous system damage and anaemia is called Pernicious Anaemia.
Symptoms of pernicious anaemia include tiredness, breathlessness, lack of energy and different sensations of the nervous system, such as pins and needles and loss of strength.
B-Dose Forte may be prescribed to help with the symptoms of pernicious anaemia, or for megaloblastic anaemia if Vitamin B12 deficiency is the diagnosed cause.
Your doctor may have prescribed B-Dose Forte Injection for another reason.
Ask your doctor if you have any questions about why B-Dose Forte Injection has been prescribed for you.
B-Dose Forte Injection is not addictive.
B-Dose Forte Injection is only available from a medical practitioner.
