Por qué sucede esto

Both garlic and losartan work to lower blood pressure. Garlic has natural properties that relax blood vessels, which adds to the effect of the medication (an additive effect). Additionally, some studies suggest garlic might slightly interfere with the enzymes in the liver that process losartan, though the blood-pressure-lowering effect is the primary concern.

You should monitor your blood pressure regularly at home. If you feel dizzy or faint, contact your GP, as your dose of losartan may need adjusting. It is best to inform your doctor before starting any high-dose garlic supplements.

Embarazo

You must not take losartan if you are pregnant or planning to become pregnant, as it can cause serious harm or death to an unborn baby, particularly during the second and third trimesters.

Cirugía o procedimientos dentales

Garlic can thin your blood and increase the risk of bleeding. You must stop taking garlic supplements at least 7 to 14 days before any planned surgery or dental work.

Taking blood-thinning medications (e.g., warfarin, clopidogrel)

Garlic supplements can significantly increase the effect of blood-thinning medicines, making you more likely to bruise or bleed dangerously.

Alcohol

It is best to avoid or strictly limit alcohol when taking garlic supplements. Both garlic and alcohol can have blood-thinning effects; combining them may increase your risk of bruising or bleeding.
