  • Some types of diuretics drugs can decrease your potassium intake. Symptoms include weakness, tiredness or leg cramps. Eating potassium-rich foods can help prevent significant loss.
  • You may experience gout attacks after prolonged use of diuretics. However, this problem is not common and your doctor can help you control it.

Central agonists

Central agonists relax your blood vessels, lowering your blood pressure. However, they can cause a greater drop in blood pressure when you walk or stand. You can experience weakness and faintness if your blood pressure is extremely low.

All medicines have side effects and high blood pressure medications do have, too. However, the benefits are more important than risks. If the side effects bother you, or if you notice severe symptoms, call your doctor as soon as possible.
