TheiCal-D3 1000 mg / 880 IU chewable tablets are not intended for use in children and adolescents. 

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

• In the case of simultaneous treatment with digitalis glycosides (cardiac glycosides derived from foxglove), cardiac arrhythmias can occur. Rigorous medical monitoring including an ECG and measurement of the blood calcium level is therefore necessary.
• In the case of simultaneous administration of diuretics of the thiazide drug class (also called water tablets), the blood calcium level should be regularly monitored since thiazides decrease the excretion of calcium in the urine.
• The absorption and thus also the effectiveness of certain antibiotics (called tetracyclines) are decreased by the simultaneous administration of TheiCal-D3 1000 mg / 880 IU chewable tablets.

These drugs should be taken at least 2 hours before or 4-6 hours after TheiCal-D3 1000mg/880IU chewable tablets.

Furthermore, other medicines such as sodium fluoride (used to strengthen the tooth enamel or to treat osteoporosis) and bisphosphonate (used to treat osteoporosis) drugs are affected by interactions.

These products should therefore be taken at least 3 hours before TheiCal-D3 1000 mg/880IU chewable tablets.

As long an interval as possible should be left between the administration of cholestyramine (a product to lower raised cholesterol levels) or laxatives such as liquid paraffin and TheiCal-D3 1000mg/880IU chewable tablets since otherwise vitamin D is not absorbed properly.

The simultaneous administration of TheiCal-D3 1000mg/880IU chewable tablets and phenytoin (a product for the treatment of epilepsy) or barbiturates (hypnotics) can result in a reduction in the effect of vitamin D.

The simultaneous administration of TheiCal-D3 1000 mg / 880 IU chewable tablets and glucocorticoids (eg: cortisone) can result in a reduction in the effect of vitamin D and to a decreased calcium level in the blood.

The additional supplementation of calcium and vitamin D should be given only under medical supervision and will require frequent monitoring of the calcium levels in the blood and urine.

Calcium can reduce the effect of levothyroxine (used to treat thyroid deficiency). For this reason, levothyroxine should be taken at least four hours before or four hours after TheiCal-D3 1000mg/880IU chewable tablets.

The effect of quinolone antibiotics may be reduced if taken at the same time as calcium. Take quinolone antibiotics two hours before or six hours after taking TheiCal-D3 1000mg/880IU chewable tablets.
