How Megacal Tablet works

This medicine combines 3 active ingredients: Calcitriol, Calcium Carbonate and Zinc. Calcitriol acts on the condition your doctor has prescribed it for. Calcium Carbonate helps your gut absorb calcium and keeps the mineral level in your blood and bones where it should be. Zinc supplies a nutrient that helps protect body cells from everyday oxidative wear and supports normal immune function.

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 may be harmful — seek medical advice immediately. It 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. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Warnings and precautions

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. 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.

Do not take Megacal if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Your doctor will confirm this medicine is suitable for you. Not for people with a high blood calcium level, or with certain kidney stones.

Interactions with other medicines

Give your doctor and pharmacist a full list of everything you take. 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.

How to store Megacal 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 Megacal Tablet

Take it at the same time each day and complete the course. Keep your follow-up appointments and any monitoring blood tests. 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.
