Calcilos Capsules

Alfacalcidol belongs to a group of medicines called vitamin D analogues. It is a type of vitamin D.

Vitamin D controls the levels of calcium and phosphate in your body. Your body needs both of these substances for healthy bones and teeth. Alfacalcidol works by increasing the amount of vitamin D in your body. This means the levels of calcium and phosphate in your body will increase too.

CALCILOS is used to treat diseases where the amount of calcium in your body needs changing. It is used to treat:

• Changes in bone caused by kidney failure (renal bone disease).
• Changes to your parathyroid glands. These are small glands found in your neck. They make a substance called the parathyroid hormone. This changes the amount of calcium in your body.
• The glands may make the amount of calcium in your blood too low (hypoparathyroidism).
• The glands may make the amount of calcium in your blood too high (hyperparathyroidism).
• Softening and deformity of the bones due to lack of calcium, phosphorus or vitamin D (rickets or osteomalacia). This can be due to an inherited birth defect or due to lack of vitamin D absorption.

Do not take CALCILOS:

• If you are hypersensitive (allergic) to alfacalcidol, arachis oil (peanut oil), soya or any of the other ingredients of CALCILOS (listed in section 6).
• If you know you have a condition called hypercalcaemia (high levels of calcium in your blood) or if you show signs of vitamin D intoxication.
• If you are pregnant or breastfeeding your baby.

Warnings and precautions

Take special care with CALCILOS:

• If you have any problems with your kidneys. This includes kidney stones. Your doctor might give you medicine that binds minerals to reduce kidney stones.
• If you are taking medicine to treat convulsions or seizures such as barbiturates. These medicines may decrease the effect of CALCILOS (see Other medicines and CALCILOS).

You should only use CALCILOS during your pregnancy or when you are breastfeeding your baby if it is considered essential by your doctor.

Other medicines and CALCILOS

Always tell your health care provider if you are taking any other medicine. (This includes all complementary or traditional medicines.)

You must tell your doctor or pharmacist if you are taking any of the following medicines:

• Thiazide diuretics, often called “water pills”: for increasing the amount of water (urine) that your body makes. You may get too much calcium in your blood.

While you are taking CALCILOS your doctor will take regular blood tests. This is very important in children or patients with kidney problems. This is to check the level of calcium and phosphate in your blood while you take CALCILOS.
