What should I know when using Diovan HCT?

When taking the blood pressure drug Diovan HCT (valsartan and hydrochlorothiazide), you should know that you need to work closely with your doctor to derive the maximum benefit with the minimum risk. You should also realize that taking a pill will probably not be all you need to do to lower your blood pressure. Your doctor may also advise you to exercise regularly, eat a low-fat diet, lose weight if you need to and, if you smoke, quit.

You should know that your doctor will probably check your blood pressure frequently while you are on Diovan HCT and may order regular urine and blood tests to monitor how the drug is affecting your kidneys, liver and your body overall. Depending on how you respond to Diovan HCT, your doctor may adjust your dose. It is important not to miss medical appointments.

You should take Diovan HCT exactly as your doctor tells you to. Do not take more or less, or take it more or less frequently than prescribed. Do not stop taking Diovan HCT without checking with your doctor first. Do not start any other drug or supplement while you are taking Diovan HCT without checking with your doctor or pharmacist first.

Call your doctor if you experience side effects from Diovan HCT, especially if they are severe or persistent. Call your doctor or 911 immediately if you experience these rare but potentially serious side effects:
  • symptoms of allergic reaction, including chest tightness, trouble breathing, hives and/or itching or swelling in your hands, face, mouth or throat
  • signs of kidney problems, including swelling in your feet, ankles or hands, or unexplained weight gain
  • skin rash
  • symptoms of low blood pressure (hypotension), including blurry vision, confusion, lightheadedness, fainting, sleepiness or weakness
  • vision problems or eye pain
  • dry mouth and/or thirst
  • drowsiness
  • weakness
  • restlessness
  • confusion
  • seizures
  • muscle fatigue, pain or cramps
  • producing less urine or urinating less frequently than normal
  • racing heartbeat
  • nausea or vomiting
