What should I know before my child takes Cozaar?

Before your child takes the blood pressure medication Cozaar (losartan), you should know that it isn't recommended for children under six or those with low-functioning kidneys. Your child also shouldn't take Cozaar if she is allergic to any of its ingredients.

Cozaar is an angiotensin II receptor blocker (ARB), which means that it reduces blood pressure by interfering with chemicals that constrict blood vessels, allowing blood to flow more smoothly.

Cozaar interacts with a number of other drugs, so make sure your child's doctor knows about any medications (prescription or over-the-counter) or supplements your child takes. Also make sure the doctor is aware of any other illnesses or medical conditions your child has, including kidney and liver disease. This information may determine whether Cozaar is safe for your child and at what dose.
Cozaar has a number of potential side effects, most of which are not serious. These include: dizziness, colds (upper respiratory infection), stuffy nose and back pain. In people taking it for diabetic kidney disease, the most common symptoms are diarrhea, tiredness, low blood sugar, chest pain, high blood potassium and low blood pressure. Let your child's doctor know if any side effects become severe or don't go away. Also seek immediate medical attention if your child experiences any of the following symptoms. They occur only rarely but could be signs of a serious, potentially fatal, reaction:
  • swelling of the face, throat, tongue, lips, eyes, hands, feet, ankles or lower legs
  • hoarseness
  • difficulty breathing or swallowing
