Why this happens
Losartan is a blood pressure medication (angiotensin II receptor blocker) and vitamin D is a fat-soluble vitamin. They are processed by different pathways in the body and do not interfere with each other's effectiveness or safety.
What you should do
You can continue to take both as prescribed. It is always a good idea to have your blood pressure and kidney function monitored regularly by your doctor while taking losartan, regardless of vitamin D use.

Important precautions
Embarazo
You must not take losartan if you are pregnant or planning to become pregnant. It can cause serious harm or death to an unborn baby, particularly if used in the second and third trimesters.
High potassium levels (Hyperkalaemia)
Losartan can increase potassium levels in your blood. Avoid using salt substitutes containing potassium or taking potassium supplements unless specifically told to by your doctor.
Food and drink warnings
Potassium-rich foods (e.g., bananas, spinach, avocados) and salt substitutes
Losartan can increase the levels of potassium in your blood. Consuming large amounts of potassium-rich foods or using salt substitutes containing potassium can lead to dangerously high potassium levels (hyperkalaemia).
Alcohol
Drinking alcohol while taking losartan can increase the medicine's blood-pressure-lowering effect. This may make you feel dizzy, lightheaded, or faint, especially when standing up.
