It may take several days to get the full benefit of this drug. Do not stop taking the medicine until your doctor tells you it is right to stop. This medicine may only be part of a treatment program that may also include changes to your diet and taking other medicines and vitamin supplements.

The most common side effects of GEMcal -Kit include headache, back pain, musculoskeletal (bone, muscle, or joint) pain, indigestion, heartburn, and diarrhea. These are generally mild and usually resolve on their own. If they do not go away or get worse, you should let your doctor know. Your doctor may be able to suggest ways of preventing or reducing the side effects.

Before using GEMcal -Kit, let your doctor know if you have any medical conditions or disorders. To make sure the medicine is safe for you, let your doctor know all the other medicines you are taking.

Treatment of Osteoporosis

Benefits of GEMcal Tablet

Treatment 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 -Kit reduces the risk of a fracture occurring in osteoporosis. It also helps in the growth and development of bones as well as maintaining strong bones. Along with medicines, eat a balanced diet rich in calcium and vitamin D, like dairy products, green leafy vegetables, etc.

Side effects of GEMcal Tablet

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them

How to use GEMcal Tablet

Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. GEMcal -Kit is to be taken on an empty stomach.

How GEMcal Tablet works

GEMcal -Kit is a combination of four medicines: calcitriol, calcium carbonate, zinc, and risedronate, which treat osteoporosis. Calcitriol is a form of vitamin D that helps your body effectively absorb calcium carbonate and supports the muscles needed to avoid falls. Calcium carbonate and zinc are minerals that help build and maintain bones. Risedronate is a bisphosphonate that works by suppressing the activity of osteoclasts, cells that destroy bone. This strengthens the bone and minimizes the risk of fractures.

Quick tips

Drink plenty of water while taking this medicine.
Along with taking GEMcal -Kit, maintain a healthy lifestyle, take a balanced diet, exercise (regular weight-bearing exercise) with your doctor's advice, and take proper measures to reduce the risk of falls.
Let your doctor know if you’re taking an iron supplement, as the absorption rate might be affected.
Inform your doctor if you have kidney problems or if you have ever had kidney stones.

Frequently asked questions

How should I take this GEMcal -Kit?

You should take GEMcal -Kit first thing in the morning on an empty stomach with a full glass of water (not juice/coffee).

Who should not take GEMcal -Kit?

Individuals should avoid using GEMcal -Kit if they are allergic to any of its ingredients. It should also be avoided in cases of high blood calcium levels (hypercalcemia), severely reduced kidney function, or bone softening not caused by vitamin D deficiency. Additionally, people with esophageal problems (such as difficulty swallowing or a very narrow food pipe) or those unable to stand or sit upright for at least 30 minutes should not use GEMcal -Kit.

What should I avoid while taking GEMcal -Kit?

While taking GEMcal -Kit, avoid lying down for at least 30 minutes afterward, as it may irritate your food pipe. Do not take calcium, antacids, or iron supplements within 2 hours of this medicine, as they can reduce its absorption. Also, avoid taking it with milk or dairy products, as they may interfere with how well it works.

What are the serious side effects of GEMcal -Kit I should watch out for?

During GEMcal -Kit treatment, contact your doctor immediately if you experience chest pain or difficulty swallowing, as these may be signs of esophageal damage. Seek help if you notice severe bone, joint, or muscle pain, jaw pain or swelling (which could indicate a rare condition called osteonecrosis of the jaw, where the jawbone doesn’t heal properly), eye pain or vision changes, or worsening of asthma (if you have or had asthma).

How long until I see improvements in bone density during GEMcal -Kit treatment?

The exact time GEMcal -Kit takes to show its benefits is not known. However, you may expect improvement in bone density in a few months of regular use. Your doctor may do scans to observe how you are doing on the GEMcal -Kit treatment.

Can I take GEMcal -Kit if I have kidney problems?

Avoid self-administering GEMcal -Kit if you have a kidney or any other disease. GEMcal -Kit requires dosage adjustment in kidney issues. Your doctor may closely monitor serum calcium/creatinine levels.

Should I continue taking GEMcal -Kit during dental work?

You should inform your dentist if you are taking GEMcal -Kit. GEMcal -Kit may need to be paused if you are having tooth extractions, getting dental implants, or experiencing jaw infections/pain.
