Losartan 50 mg is used to treat hypertension and lower the risk of stroke for individuals with heart disease, states Drugs.com. It may also be prescribed to type 2 diabetics with high blood pressure to slow long-term kidney damage.
Losartan prevents blood vessels from narrowing, which improves blood circulation and decreases blood pressure. The average dose given to adults is 50 mg, which is initially taken orally once daily, but may be divided into two doses of 25 to 100 mg for maintenance dosages. It may be taken with or without food, according to Drugs.com.
Pregnant women should not take Losartan, as it may cause injury or death to the unborn baby, notes Drugs.com. Diabetics should not combine Losartan with any medication that contains aliskiren.
