1. What is ALFACALCIDOLO DOC and what is it used for

ALFACALCIDOLO DOC contains alfacalcidol, an analogue of vitamin D.
ALFACALCIDOLO DOC works by increasing the amount of vitamin D in your body. This means that
even the levels of calcium and phosphate in your body will increase.
ALFACALCIDOLO DOC is indicated in adults for the treatment of:

• Altered function of the parathyroid glands caused by renal insufficiency, with resulting bone alterations.
• Low levels of calcium due to reduced function of the parathyroid glands, located in the neck (hypocalcemia due to hypoparathyroidism, post-operative, idiopathic).
• Weakening of the bones after menopause, as an adjunct to specific treatment, when the formation of active vitamin D in the kidney is compromised.

ALFACALCIDOLO DOC is indicated in adults, adolescents and children over 6 years of age and with a
body weight greater than 20 kg:

• weakening and deformation of the bones due to calcium deficiency caused by altered vitamin D metabolism (Rickets due to pseudo-deficiency (D-dependent))
• vitamin D-resistant hypophosphatemic rickets and osteomalacia.

2. What you need to know before taking ALFACALCIDOLO DOC

Do not take ALFACALCIDOLO DOC

• if you are allergic to alfacalcidol or any of the other ingredients of this medicine (listed in section 6).
• if you have signs of vitamin D toxicity.
• if you have high levels of calcium in your blood (hypercalcemia) the symptoms can be fatigue, nausea, vomiting, frequent need to urinate and headache. This means that you have high levels of calcium in your blood.
• if you suffer from hyperphosphataemia (increased phosphate levels in the blood) and hypermagnesaemia (increased magnesium levels in the blood).

If you are not sure whether any of the above conditions apply to you, talk to your doctor before
taking ALFACALCIDOLO DOC.

Warnings and precautions
Talk to your doctor or pharmacist before taking ALFACALCIDOLO DOC.
Because alfacalcidol is an analogue of vitamin D, during treatment with ALFACALCIDOLO DOC
you should not take vitamin D or its derivatives as excessive doses of vitamin D can cause you
serious harm.
Because excessive doses of ALFACALCIDOLO DOC can cause an increase in calcium levels in
the blood and sometimes in the urine, your doctor will ask you to undergo tests to monitor calcium levels in
the blood and to establish the dose of ALFACALCIDOLO DOC suitable for you.
High concentrations of calcium in the blood can in fact cause serious reactions that in some cases may
require emergency therapies. Furthermore, the presence of high concentrations of calcium in the blood for prolonged
periods of time can lead to calcification.
Other symptoms of increased calcium levels in the blood are muscle and bone pain, muscle weakness, confusion dehydration, anorexia, fatigue, nausea, vomiting, constipation, increased
amount of urine produced, sweating, headache, intense thirst, increased blood pressure,
drowsiness.
If you experience an increase in calcium content in the blood, your doctor will tell you to stop the
treatment with ALFACALCIDOLO DOC until the situation normalizes. Afterwards, they may
decide to lower the dose of ALFACALCIDOLO DOC for your treatment.
If you are being treated with digitalis (a drug extracted from a plant that contains substances that stimulate the
heart muscle), your doctor will be cautious when prescribing ALFACALCIDOLO DOC as
the increase in calcium concentrations in the blood resulting from taking ALFACALCIDOLO DOC
can cause heart rhythm disturbances.
If you are taking phosphate-binding substances, your doctor may decide to adjust their dose as
ALFACALCIDOLO DOC affects the transport of phosphates in the intestine, kidney and bones.
Talk to your doctor or pharmacist before taking ALFACALCIDOLO DOC:

• if you are taking any of the medicines in the following section “Other medicines and ALFACALCIDOLO DOC”.
• if you have kidney problems. This includes if you have kidney stones.
• if you have granulomatous diseases such as sarcoidosis. You may be more sensitive to alfacalcidol.
• if you suffer from atherosclerosis (a condition in which the inside of the artery narrows).

Children and adolescents
The use of ALFACALCIDOLO DOC is not recommended in children aged 6 years or less and/or
weighing 20 kg or less in cases of pseudo-deficiency (D-dependent) rickets and vitamin D-resistant hypophosphatemic rickets and osteomalacia).
The use of ALFACALCIDOLO DOC is not recommended in children and adolescents in cases of
altered function of the parathyroid glands caused by renal insufficiency, with resulting
bone alterations; low levels of calcium due to reduced function of the parathyroid glands, a
due to lack of clinical data.
ALFACALCIDOLO DOC is not indicated in children and adolescents as an adjunct to
specific treatment for bone weakening after menopause.

Other medicines and ALFACALCIDOLO DOC
Tell your doctor or pharmacist if you are taking, have recently taken or might take any
other medicines.
If you take other medicines while taking ALFACALCIDOLO DOC, the therapeutic action may be
affected.
In particular, taking ALFACALCIDOLO DOC together with the following medicines is not recommended:

• Thiazide diuretics (medicines used to increase urine production). These medicines can cause an increase in calcium levels in the blood.
• Medicines and supplements containing vitamin D. They can increase calcium levels in the blood.
• Medicines and supplements containing calcium. They can increase calcium levels in the blood.
• Anticonvulsants such as barbiturates, phenytoin, carbamazepine or primidone (medicines used to treat seizures and epilepsy). These medicines can reduce your body's response to taking ALFACALCIDOLO DOC, resulting in the need to increase your dose.
• Antacids and magnesium-based laxatives. Taking them at the same time with ALFACALCIDOLO DOC can cause an increase in magnesium levels in the blood.
• Preparations containing aluminum as the simultaneous administration of ALFACALCIDOLO DOC can cause an increase in aluminum levels in the blood.
• Cholestyramine (medicine used to lower cholesterol levels in the blood) and orlistat (medicine used to treat obesity) as they can reduce the intestinal absorption of ALFACALCIDOLO DOC.
• Digitalis (medicine used for heart problems). This association should be carefully monitored.
• Rifampicin and isoniazid. This association can reduce the effectiveness of vitamin D.
