About CALCIJET 1MCG INJECTION 1ML

CALCIJET 1MCG INJECTION 1ML is a prescription injection used to treat and manage low calcium levels and overactive parathyroid glands in patients undergoing chronic kidney dialysis. It helps keep calcium and phosphorus balanced in your body when your kidneys can no longer do so. By maintaining these levels, it helps protect your bones from becoming weak or brittle.

This medicine is typically injected during your regular dialysis sessions, making its schedule consistent with your treatment plan. Since it is injected directly into your bloodstream, food does not affect how it is absorbed. However, following a specialised diet low in phosphorus is key to helping this medicine work effectively.

While taking CALCIJET 1MCG INJECTION 1ML, you may experience mild side effects like a temporary headache, nausea, or a dry mouth. It is important to watch for serious signs of high calcium levels, such as extreme fatigue, persistent vomiting, or muscle weakness, and contact your doctor immediately if these occur.

Talk to your doctor before starting this medicine if you have a history of high calcium levels or vitamin D toxicity. Do not take this if you already have high blood calcium levels, as injecting more can cause serious medical complications.

Let your doctor know about all other medications you take, especially water pills, heart medicines, or antacids, as they can interact with CALCIJET 1MCG INJECTION 1ML and affect your calcium levels. If you are pregnant, breastfeeding, or an older adult, consult your doctor to ensure this treatment is safe for your specific needs.

Uses of CALCIJET 1MCG INJECTION 1ML

CALCIJET 1MCG INJECTION 1ML is used to treat and manage low calcium levels and overactive parathyroid glands in patients undergoing chronic kidney dialysis. The detailed uses of CALCIJET 1MCG INJECTION 1ML are as follows:

  • Secondary hyperparathyroidism in kidney dialysis patients: It helps reduce the overproduction of parathyroid hormone, preventing the body from pulling too much calcium out of your bones.
  • Hypocalcaemia in kidney dialysis patients: It raises low blood calcium levels, helping to keep bones strong and muscles functioning properly.

Key Benefits

CALCIJET 1MCG INJECTION 1ML helps manage mineral and bone disorders associated with chronic kidney disease by maintaining healthy calcium and parathyroid hormone levels. With regular use as prescribed, it helps protect bone strength, reduce complications, and support long-term skeletal health, especially in patients undergoing dialysis.

  • Supports Strong, Healthy Bones: By helping regulate calcium and parathyroid hormone levels, this medicine helps prevent bone thinning, bone pain, and weakness, reducing the risk of fractures and supporting better mobility.
  • Helps Manage Bone Disorders in Chronic Kidney Disease: This medicine helps control the mineral imbalances caused by chronic kidney disease, protecting the skeletal system and supporting long-term bone health.
  • Provides Reliable Treatment for Dialysis Patients: Because this medicine is administered directly into a vein, it bypasses the digestive system and delivers reliable treatment, making it especially beneficial for patients receiving dialysis or those who cannot effectively absorb oral vitamin therapy.

Directions for Use

  • CALCIJET 1MCG INJECTION 1ML should be administered only under the supervision of a healthcare professional.
  • The appropriate dosage and frequency of administration will be determined based on your individual medical needs.
  • Self-administration is not recommended.

How CALCIJET 1MCG INJECTION 1ML Works

CALCIJET 1MCG INJECTION 1ML contains calcitriol, which is an active form of vitamin D. Normally, healthy kidneys convert the vitamin D you get from food and sunlight into this active form. Once converted, it tells your gut to absorb calcium and signals your parathyroid glands to stop releasing too much hormone. When kidneys fail, they can no longer produce enough of this active form. Injecting CALCIJET 1MCG INJECTION 1ML replaces this essential substance directly in your bloodstream. This allows your body to safely absorb calcium and sends a direct signal to the parathyroid glands to stop overproducing the hormones that weaken your bones.
