Let your provider know if you have a history of kidney disease, liver disease, severe heart failure, high potassium levels, or dehydration. Tell them about any other medications you take—especially potassium supplements, salt substitutes containing potassium, lithium, or NSAID pain relievers like ibuprofen (Advil) and naproxen (Aleve). These can harm kidney function and reduce the effectiveness of losartan (Cozaar).

Do not take losartan if you are pregnant or plan to become pregnant. ARBs can cause birth defects or fetal death.

Losartan (Cozaar) is currently only available via prescription. This means the use of this drug must be authorized by a licensed healthcare provider.

Providers on Sesame can write a prescription—or refill an existing one—during a virtual or in-person visit. Depending on the medication, you can arrange for same-day pickup at a pharmacy near you. Book an online consultation with a real, licensed provider on Sesame today to determine whether or not losartan is right for you.

Note that all prescriptions are at the discretion of your healthcare provider. Providers on Sesame cannot prescribe controlled substances.

ARBs treat high blood pressure and protect the heart and the kidneys by relaxing blood vessels. On Sesame, providers can prescribe or refill several ARBs, including:

• Single-agent ARBs: Losartan (Cozaar), Valsartan (Diovan), Olmesartan (Benicar), Telmisartan (Micardis), and Irbesartan (Avapro)
• Combination ARBs (with a diuretic): Losartan-HCTZ (Hyzaar) and Valsartan-HCTZ (Diovan HCT)
