Frequently asked questions
Losartan or telmisartan?
Both are ARBs; telmisartan lasts a little longer. The best choice depends on your blood pressure pattern and other conditions.
Does losartan help with uric acid?
It has a mild uric-acid-lowering effect, which can be a bonus for some people with gout and high blood pressure.
