What It's For & How To Take
Clonidine works in your brain to relax pressure on your blood vessels. This medication is used to treat high blood pressure. Clonidine is also used for treatment of other conditions not listed here. If you are using this medication for something other than high blood pressure, discuss this with your doctor or pharmacist.
If high blood pressure is not treated, your blood vessels will harden, and this will eventually lead to a heart attack or a stroke. High blood pressure may also cause vision problems, kidney failure and eventually heart failure.
Clonidine is usually taken twice daily or as directed by your doctor. You may take this medication with or without food. Take clonidine at the same time each day with a full glass of water.
If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
Keep using this medication, even if you don’t feel sick. You may need to treat your high blood pressure for many years.
Your blood pressure should be checked often to make sure the medication is working correctly.
