1. What Ergocalciferol is for

Ergocalciferol is a form of Vitamin D.

Ergocalciferol increases levels of calcium and phosphate in the blood by increasing their absorption from the gut and reducing the amount removed by the kidneys.

Ergocalciferol is used to treat:

  • Low levels of phosphate in the blood
  • Weak bones and teeth (called ‘Rickets’)
  • Other problems with how bones are formed.

These disorders are due to poor absorption of Vitamin D within the body usually caused by diseases of the gut, liver or gall bladder.

It is important that you have this medicine so that your bones and teeth form properly.

2. Before you are given Ergocalciferol

You should not be given Ergocalciferol if:

  • You are allergic to Vitamin D
  • You are allergic to the other ingredient of Ergocalciferol (see section 6)
  • You have high levels of calcium in your blood
  • You already have high levels of Vitamin D in your blood, or if you are especially sensitive to Vitamin D
  • You have kidney problems.
  • You have an accumulation of calcium salts in the body's tissue.

If any of the above applies to you talk to your doctor or nurse.

Check with your doctor before being given Ergocalciferol:

  • As it is important that you are taking enough calcium in your diet so that your body can respond properly to your medicine
  • If you have heart disease, problems with your kidneys or with your circulation
  • If you have kidney stones
  • If you have low levels of parathyroid hormone (PTH)
  • If you already have high levels of Vitamin D in your blood or if you are especially sensitive to Vitamin D.

Tell your doctor if you are taking any of the following medicines:

  • Drugs for heart disease such as digoxin or verapamil as these can cause high levels of calcium in the blood leading to an irregular or fast heart beat
  • Antacids containing magnesium for indigestion. If you are on kidney dialysis this can lead to high levels of magnesium in the blood which causes muscle weakness, low blood pressure, depression and coma
  • Thiazide diuretics to relieve water retention such as bendrofluazide as these can lead to high levels of calcium if your body does not produce enough parathyroid hormone (PTH)
  • Phenytoin, carbamazepine, primidone or phenobarbital used for the treatment of epilepsy as these may cause Ergocalciferol to be lost from the body too quickly
  • Any other medicine, including medicines obtained without a prescription.

If any of the above applies to you talk to your doctor or nurse before using Ergocalciferol.

Pregnancy and breast-feeding

If you are pregnant or trying to become pregnant tell your doctor or nurse before being given Ergocalciferol. Your doctor will tell you if you need to have Ergocalciferol and you are pregnant.

You should not be given Ergocalciferol if you are breast-feeding. This medicine will be given to you in pregnancy only if your doctor decides it is necessary.

Driving and using machines

3. How you will be given Ergocalciferol

Medical check-ups

While you are receiving this medicine, your doctor will test your blood and urine regularly. This is to make sure that your medicine is working properly and that the dose you are taking is right for you. If the level of sugar in your blood becomes higher than normal your doctor will stop your treatment of Ergocalciferol.

If you are given more Ergocalciferol than you should

If you think you have been given too much Ergocalciferol you should tell your doctor.

If you have too much Ergocalciferol you may get increased calcium levels in your blood which may lead to the following: feeling sick, feeling weak, weight loss, stiffness, constipation, diarrhoea, hallucinations, fainting, increased levels of urination or feeling thirsty.
