Dihydrotachysterol is a form of vitamin D. ויטמין D helps you to absorb calcium from the foods you eat. You need calcium to keep your bones strong, and to help your muscles and nerves work properly. If you have a low level of calcium in your blood, it can cause a number of different symptoms, including muscle cramps, pain and twitching. Low levels of calcium can be caused by a problem with your parathyroid glands, called hypoparathyroidism. Dihydrotachysterol is used to treat low blood levels of calcium when caused by hypoparathyroidism.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking dihydrotachysterol it is important that your doctor knows:

  • If you are allergic to peanuts or soya. If so, you must not take this medicine.

  • אם את בהריון או מניקה.

  • If you have sarcoidosis. This is a condition causing inflammation, particularly in your lungs and lymph system. Sarcoidosis may make you more sensitive to dihydrotachysterol than normal.

  • אם אתה נוטל תרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

  • אם אי פעם הייתה לך תגובה אלרגית לתרופה.

  • Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about dihydrotachysterol and a full list of side-effects which you may experience from taking it.

  • Take dihydrotachysterol exactly as your doctor tells you to. It is likely you will be asked to take 3-5 ml for the first three days, and then your dose will be adjusted depending on the results of a blood test. You could then be asked to take a dose each day, on alternate days, or several times a week. Your doctor will tell you what is right for you, and how much to take for each of your doses.

  • Make sure you understand how to measure out your doses using the dropper. You can ask your doctor, nurse or pharmacist to explain this to you again if you are uncertain.

  • You can take dihydrotachysterol before or after meals.

  • If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a forgotten dose.

  • Keep your regular doctor's appointments so your progress can be monitored. You will need to have regular blood tests while you are taking this medicine to make sure that the dose you are taking is correct for you.

  • You should consider wearing a MedicAlert® bracelet (or similar), or carry some kind of ID with you, to identify yourself as having hypoparathyroidism. This is so that if you collapse, are confused or are injured, doctors will know that you need prompt treatment with calcium.

  • Eating foods rich in vitamin D and calcium may help, such as oily fish (sardine, herring, salmon and tuna), liver, dairy products and eggs.

  • If you buy any medicines, check with a pharmacist that they are suitable for you to take with dihydrotachysterol.

  • Treatment with dihydrotachysterol is usually long-term. Continue to take it regularly unless you are advised otherwise by your doctor.

  • If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking dihydrotachysterol.
