Key benefits

  • In Treatment and prevention of Osteoporosis Osteoporosis is a common condition that causes bones to become fragile and brittle so that they break (fracture) more easily. Fractures may be painful and restrict a person’s ability to carry out their normal daily tasks. Gemcal-DS Tablet helps in the treatment and prevention of osteoporosis. This medicine helps in the growth and development of bones as well as maintain strong bones. Since osteoporosis doesn’t usually have any symptoms such as pain (until a fracture occurs) you might not ‘feel’ any immediate benefit from your treatment with Gemcal-DS Tablet. Keep taking it until your doctor asks you to stop. Along with medicines

How Gemcal DS Tablet works

Gemcal-DS Tablet is a combination of Calcitriol, Calcium Carbonate, and Vitamin K2-7. Calcitriol is the active form of Vitamin D. It raises Vitamin D levels in your blood. This in turn raises calcium levels in your blood by helping you absorb more calcium from your intestine. Calcium carbonate is a dietary supplement used when the amount of calcium taken in the diet is not enough. Vitamin K2-7 plays a central role in the metabolism of calcium, the main mineral found in your bones and teeth. Vitamin K2-7 activates the calcium-binding actions of two proteins : matrix GLA protein and osteocalcin, which help to build and maintain bone health.

How to take Gemcal DS Tablet

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 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 Gemcal DS 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. 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 Gemcal DS 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 Gemcal DS Tablet

Gemcal-DS Tablet is used in the treatment of calcium deficiency. Inform your doctor if you have kidney problems, or if you have ever had kidney stones. Let your doctor know if you are taking any other medications like for bone disorders, antihypertensives, antibiotics, antacids, other calcium supplements, or medicines for heart disease. Inform your doctor if you are taking an iron supplement, as the absorption rate might be affected. Include calcium-rich food in your diet like milk, cheese, yogurt, calcium-fortified soya milk, and green leafy vegetables like spinach.
