How Chrominac-A Tablet works

This medicine combines 4 active ingredients: Biotin, Acetylcysteine, Alfacalcidol and Chromium Picolinate. Biotin replaces a B vitamin your body needs to make red blood cells, to keep nerves healthy and to release energy from food. Acetylcysteine loosens and thins the mucus in your airways so a cough clears it more easily, and eases the tightness that comes with congestion. Alfacalcidol acts on the condition your doctor has prescribed it for. Chromium Picolinate supplies a vitamin, mineral or nutrient that your diet may not be providing in sufficient amount.

How to take Chrominac-A Tablet

Swallow the tablet whole with a glass of water. Do not chew, crush or break it unless your doctor has told you to. Take it with or after 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 is unlikely to cause serious harm, because the body passes surplus B vitamins out in the urine. It can cause vomiting, severe drowsiness, a racing heart and, with codeine, dangerously slow breathing. It may be harmful — seek medical advice immediately. 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.

Side effects of Chrominac-A Tablet

Most side effects of Chrominac-A are mild and settle as the body adjusts. Reported side effects include:

  • Nausea
  • Stomach upset
  • Harmless bright yellow urine
  • Loose motions
  • Vomiting
  • Drowsiness
  • Tremor
  • Fast heartbeat
  • Headache
  • Dizziness
  • Constipation

Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Warnings and precautions

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. See a doctor if a cough lasts more than a week, or comes with fever, breathlessness, chest pain or blood in the sputum. Do not give cough and cold preparations to young children except on a doctor's advice. Do not combine two cough preparations — they frequently contain the same ingredients, and the doses add up. Preparations containing codeine can cause dependence and must be used only for the period your doctor specifies. This is a prescription-only medicine. Take it exactly as your doctor has directed, for the period directed. Do not share it with anyone else, even if their symptoms seem the same. Tell your doctor about every other medicine, supplement and herbal product you take. Report any unexpected or severe symptom to your doctor rather than stopping on your own. 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 Chrominac-A if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Codeine-containing preparations are not for children, or for anyone with breathing difficulty. Your doctor will confirm this medicine is suitable for you.

Interactions with other medicines

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. Sedating ingredients add to the effect of alcohol and sleeping tablets. Decongestants such as phenylephrine and pseudoephedrine can raise blood pressure — tell your doctor if you are hypertensive. Give your doctor and pharmacist a full list of everything you take. 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 Chrominac-A Tablet

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

Expert advice for Chrominac-A Tablet

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. Drink plenty of water — it thins mucus better than any syrup. Steam inhalation helps congestion and costs nothing. Measure the dose with the cup supplied. Take it at the same time each day and complete the course. Keep your follow-up appointments and any monitoring blood tests. Take it with food unless the pack says otherwise. Have deficiencies confirmed and rechecked by blood test rather than supplementing indefinitely.
