How Fourts B Mega Capsule works

This medicine combines 17 active ingredients: Vitamin d, Vitamin c, Zinc, Vitamin e, D-panthenol, Thiamine, Riboflavin, Pyridoxine, Selenium, Lysine, Potassium Iodide, Niacinamide, Copper Sulphate, Manganese Sulphate, Vitamin a, Methylcobalamin and Myo-inositol. Vitamin d helps your gut absorb calcium and keeps the mineral level in your blood and bones where it should be. Vitamin c supplies a nutrient that helps protect body cells from everyday oxidative wear and supports normal immune function. Zinc supplies a nutrient that helps protect body cells from everyday oxidative wear and supports normal immune function. Vitamin e supplies a nutrient that helps protect body cells from everyday oxidative wear and supports normal immune function. D-panthenol holds water in the skin and restores the barrier that dry, damaged skin has lost. Thiamine replaces a B vitamin your body needs to make red blood cells, to keep nerves healthy and to release energy from food. Riboflavin replaces a B vitamin your body needs to make red blood cells, to keep nerves healthy and to release energy from food. Pyridoxine replaces a B vitamin your body needs to make red blood cells, to keep nerves healthy and to release energy from food. Selenium supplies a nutrient that helps protect body cells from everyday oxidative wear and supports normal immune function. Lysine supplies protein and amino acids, the building blocks your body uses to repair and maintain muscle and tissue. Potassium Iodide supplies a vitamin, mineral or nutrient that your diet may not be providing in sufficient amount. Niacinamide replaces a B vitamin your body needs to make red blood cells, to keep nerves healthy and to release energy from food. Copper Sulphate supplies a vitamin, mineral or nutrient that your diet may not be providing in sufficient amount. Manganese Sulphate supplies a vitamin, mineral or nutrient that your diet may not be providing in sufficient amount. Vitamin a supplies a nutrient that helps protect body cells from everyday oxidative wear and supports normal immune function. Methylcobalamin replaces a B vitamin your body needs to make red blood cells, to keep nerves healthy and to release energy from food. Myo-inositol replaces a B vitamin your body needs to make red blood cells, to keep nerves healthy and to release energy from food.

How to take Fourts B Mega Capsule

Swallow the capsule whole with a glass of water. Do not chew, crush or break it unless your doctor has told you to. Take it with food. Taking it at about the same time each day helps you remember. Follow the dose and the duration written on your prescription.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.

If you take too much

An overdose of this medicine can raise blood calcium dangerously, causing thirst, frequent urination, vomiting, confusion and kidney damage. It can cause vomiting, stomach pain and, with some minerals, damage over the longer term. It is not a realistic risk from a moisturiser used on the skin. It is unlikely to cause serious harm, because the body passes surplus B vitamins out in the urine. It in very large doses taken over months can itself damage nerves, causing numbness and unsteadiness. It may cause stomach upset and, with prolonged excess, puts avoidable load on the kidneys. It can cause vomiting and stomach pain, and with iron can be dangerous, especially in children. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

  • Mild stinging on broken skin
  • Greasy feel

  • a rash

Warnings and precautions

Do not take more than your doctor has advised. Vitamin D builds up in the body and too much raises blood calcium, causing thirst, frequent urination, nausea and confusion. High-dose weekly or monthly sachets are prescription strengths — do not repeat one because you missed a week. Tell your doctor if you have had kidney stones or have kidney disease. A supplement supports a normal diet; it does not prevent or treat infection. Zinc on an empty stomach commonly causes nausea — take it with food. Very high doses of vitamin A over a long period can be harmful, particularly in pregnancy. Do not take several products containing the same nutrient at once; the totals add up. Apply generously and often — several times a day, and always within a few minutes of a bath while the skin is still damp. Some paraffin-based emollients are flammable when they soak into clothing and bedding. Keep away from open flames and cigarettes. Stop if the skin becomes more red, itchy or sore after use. Tingling, numbness or burning in the hands and feet should be assessed by a doctor rather than self-treated — a supplement does not address the cause. Folic acid can mask a vitamin B12 deficiency while nerve damage continues, so B12 should be checked before taking folic acid long term. Bright yellow urine after a B-complex dose is expected and harmless. Do not take high-dose vitamin B6 for long periods without medical advice — sustained excess can cause nerve damage. Tell your doctor before taking a protein supplement if you have kidney disease — the protein load matters. Drink plenty of water while taking a protein supplement. Check the label for milk or soy if you have an allergy or are lactose intolerant. A supplement is not a substitute for a balanced diet or for treating the cause of a symptom. Iron makes stools black and can cause constipation — this is expected, but tell your doctor if it troubles you. Keep iron-containing products well out of reach of children; an overdose in a small child is a medical emergency. Check the labels of everything you take so you do not double up on the same nutrient.

Do not take Fourts B Mega if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with a high blood calcium level, or with certain kidney stones. Not for people with inherited disorders of amino-acid metabolism, or with a known allergy to the protein source.

Interactions with other medicines

Calcium reduces the absorption of thyroid tablets, several antibiotics and iron — separate them by a few hours. Water tablets of the thiazide group raise calcium further when combined. Zinc and other minerals reduce the absorption of some antibiotics — separate them by a few hours. Tell your doctor if you take a blood thinner, as high-dose vitamin E can add to its effect. No significant interactions are expected. Long-term metformin, acid-reducing medicines and some anti-epileptics lower B12 or folate levels. Tell your doctor if you take levodopa, as vitamin B6 can reduce its effect. No significant medicine interactions are expected for most protein supplements. Iron, calcium, zinc and magnesium reduce the absorption of thyroid tablets and several antibiotics — separate them by a few hours. Tea and coffee taken with iron reduce how much is absorbed; vitamin C increases it.

How to store Fourts B Mega Capsule

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.

Expert advice for Fourts B Mega Capsule

Take calcium with food, and split the day's total if you take a large amount. Sunlight helps your body make its own vitamin D. Have your level rechecked as your doctor advises rather than continuing high doses indefinitely. Take it with food to reduce nausea. A varied diet remains the best source of these nutrients. Use lukewarm water, a soap substitute and short baths. Smooth it on in the direction the hair grows rather than rubbing it in hard. Keep using it when the skin looks normal — that is what prevents the next flare. A supplement corrects a deficiency; it is not a general energy tonic. If you are on it for nerve symptoms, keep your review appointment so the underlying cause is looked for. Mix it as directed on the pack; a thicker mix is not a stronger one. Use it alongside meals, not instead of them, unless your dietitian has said otherwise. Take it with food unless the pack says otherwise. Have deficiencies confirmed and rechecked by blood test rather than supplementing indefinitely.
