What is Thorens?

Thorens is an oral medicine that comes in the form of drops. It is packed with Vitamin D3 which means that it is often used to boost the availability of that vitamin in patients who need more of it. Vitamin D3 helps the body to absorb calcium naturally and to build stronger bones. 

What is Thorens used for?

Defective bone growth from a lack of Vitamin D3 can be treated with Thorens. Rickets, a condition often associated with childhood, and osteomalacia, more frequently found in adults, are common complaints that Thorens can be used to help with. Some people who cannot absorb Vitamin D3 naturally may also use this drug therapy. 

How to use Thorens

Taken orally, Thorens is best consumed along with a large meal. By taking it at the same time as your usual eating regime, the drug is better absorbed by the body, thereby helping to boost its Vitamin D3 intake. Apply the medication to food using the medicine's dropper applicator which operates like a pipette. Thorens should be mixed with solid food only when administering it to children. 

Dosage

Dosage advice varies depending on individual cases. However, patients should know that a single drop of Thorens contains 200 IU of Vitamin D3. Typically, adults will be prescribed three to four drops per day. When preventing Vitamin D3 deficiencies in children, two to three drops per day may be prescribed as a common dosage with lower amounts for babies. More is usually administered when known deficiencies in children are being treated. 

Side Effects

The are two main side effects known to be associated with Thorens:

  • Hypercalcaemia may occur which results in a build-up of calcium in the blood stream. 
  • Hypercalciuria is also known to affect some patients, a condition of too much calcium in the patient's urine. 

When not to take Thorens

Do not take Thorens if you have been advised by a medical professional not to do so. It should be avoided if you have sarcoidosis, an immune system disorder relating to Vitamin D3, or are undergoing certain heart-related therapies, such as taking cardiac glycosides. Refrain from taking Thorens if you have a kidney disorder, are taking Vitamin D3-enriched foods, taking calcium supplements or have been taking Vitamin D3 in another form. If you will be exposed to excessive sunlight, avoid this treatment type, as well.

Advice for Thorens with pregnancy / driving / alcohol

When pregnant or breastfeeding, it is recommended that you obtain professional advice before taking this medicine. When prescribed during pregnancy, stay under two drops of Thorens per day unless you have been told otherwise. Driving should be unaffected by people taking this drug and there is no known problem associated with moderate alcohol consumption.
