1. WHAT ALFACALCIDOL CAPSULES ARE AND WHAT THEY ARE USED FOR
Each capsule contains 0.25, 0.5 or 1 microgram of alfacalcidol. Alfacalcidol is a vitamin D product that helps the body to use calcium and phosphate for healthy bones.
Your medicine is used to treat renal (kidney) bone diseases as well as rickets, osteomalacia (which is a disease causing the bones to soften and weaken) and patients with high or low activity of the parathyroid gland. It is used to maintain normal calcium levels within the body.
2. BEFORE YOU TAKE ALFACALCIDOL CAPSULES Do not take Alfacalcidol Capsules if:
• You are sensitive to any of the ingredients in the medicine (listed in section 6).
• You have a condition called hypercalcaemia. This means you have high levels of calcium in your blood.
• You have a condition called calcification. This means you have high levels of calcium in your body tissues.
These capsules contain small amounts of peanut oil (arachis oil), which may cause a severe allergic reaction in sensitive people.
Before taking Alfacalcidol Capsules, tell your doctor if:
• You have kidney problems
• If you are taking another type of medicine called a cardiac glycoside, such as digoxin. These medicines are used to treat problems with your heart.
You may get too much calcium or phosphate in your blood when you take this medicine. Please read section 4 of this leaflet so you can spot any signs that may be happening to you. Your doctor may need to change your dose. While you are taking Alfacalcidol your doctor will take regular blood tests. This is very important in children, patients with kidney problems, or patients on a high dose of medicine. This is to check the level of calcium and phosphate in your blood while you take your medicine.
Your doctor may prescribe another medicine called a phosphate binding agent to take as well as Alfacalcidol. This will help to keep the right amount of phosphate in your blood.
Taking Alfacalcidol Capsules with other medicines
Tell your doctor if you are taking or have recently taken any other medicines, including those obtained without a prescription. Such medicines include:
• Cardiac glycosides, such as digoxin used for heart problems
• Barbiturates e.g. phenobarbital, or anticonvulsants (anti-epileptic medication) e.g. phenytoin
• Mineral oil, colestyramine, colestipol or sucralfate
• Large amounts of aluminium-containing antacids e.g. aluminium hydroxide
• Magnesium-containing antacids or laxatives e.g. magnesium hydroxide
• Preparations containing calcium e.g. calcium gluconate
• Diuretics (“water tablets”) e.g. bendroflumethiazide
• Any other preparations containing vitamin D, e.g. ergocalciferol.
Pregnancy and breast-feeding

Important information about some of the ingredients of Alfacalcidol Capsules
The capsule contains small amounts of sorbitol, which should be avoided if you have an intolerance to fructose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine. Sorbitol may cause stomach upset and diarrhoea.
These capsules contain arachis oil (peanut oil). If you are allergic to peanut or soya, do not use Alfacalcidol Capsules

3. HOW ALFACALCIDOL CAPSULES SHOULD BE TAKEN
Always take Alfacalcidol Capsules exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
The capsules should be swallowed whole with a drink of water.
The usual starting dose is:
Starting dose:
Adults
Children 20 kg and over Children under 20 kg The Elderly
Alfacalcidol per day
1.0 microgram
1.0 microgram Not recommended 0.5 microgram
At the beginning of your treatment calcium levels in your blood should be measured weekly. The dosage can then be adjusted to achieve the correct response. Doses may be increased by 0.25 - 0.5 microgram per day. When the correct dosage has been found your calcium levels may be measured every 2 - 4 weeks.
If your diet is deficient in calcium, Alfacalcidol may not work as well.
Levels of phosphate in your blood may also be measured regularly, especially if you suffer from kidney problems.
If you take more Alfacalcidol Capsules than you should
If you (or someone else) swallow a lot of the capsules all together, or if you think a child has accidentally swallowed any of the capsules, contact your nearest hospital casualty department or your doctor immediately. If you or anyone else has taken too many capsules, there may be signs of nausea, vomiting, weakness, sweating, diarrhoea, headache, vertigo, thirst and excessive urination.
If you forget to take Alfacalcidol Capsules
If you forget to take a capsule, take one as soon as you remember, unless it is nearly time to take the next one. Do not take a double dose to make up for missed doses. Take the remaining doses at the correct time.
