Some medicines can alter the way this medicine works. On the other hand, Domnisol, or its active ingredient calcifediol monohydrate can affect the effectiveness of other drugs taken simultaneously.

Therefore, they may interact with the following drugs:

• Medicines used to treat epilepsy (such as phenytoin, phenobarbital, and primidone) and other enzyme-inducing drugs (favouring the reduction of Domnisol effect).
• Heart medicines and/or hypertension and cardiac glycosides, thiazide diuretics or verapamil.
• Cholestyramine, colestipol (for cholesterol), orlistat (for obesity). Intake of these drugs and calcifediol monohydrate should be separated at least 2 hours
• Mineral oil or paraffin, (laxatives): Using another type of laxative or separating intake of both drugs is recommended.
• Some antibiotics (such as penicillin, neomycin, and chloramphenicol)
• Magnesium salts
• Other products with Vitamin D
• Calcium supplements
• Corticosteroids (anti-inflammatory drugs).

Some foods and drinks are supplemented with vitamin D. This should be considered since the effects could be added to the effects of this medicine and therefore be excessive.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Domnisol is not recommended during pregnancy.

Calcifediol monohydrate is poorly excreted into breast milk. Nevertheless, in case you are a breast-feeding woman, this should be considered by your doctor or pharmacist when prescribing a vitamin D supplement.

If you take more Domnisol than the dose prescribed by your doctor (overdose) and/or for a long time, hypercalcemia (high blood calcium levels) and phosphates in urine and blood may appear, possibly leading to kidney failure. Some symptoms of toxicity can appear early and others later. Initial symptoms include weakness, fatigue, headache, loss of appetite, dry mouth, digestive disorders such as vomiting, abdominal cramps, constipation or diarrhoea, increased thirst, increased urination, muscle pain. Some symptoms that may occur later are itching, weight loss, stunted growth in children, kidney disorders, intolerance to sunlight, conjunctivitis, increased cholesterol, transaminases, inflammation of the pancreas, calcification (calcium salts deposits) in blood vessels and other tissues such as tendons and muscles, increased blood pressure, mental disorders, irregular heartbeat. The symptoms of overdose usually improve or disappear when treatment is stopped, but if intoxication is severe kidney or heart failure can occur.
