Catapres Warnings and Precautions

Specific Catapres Warnings and Precautions

Some precautions and warnings to be aware of prior to taking Catapres include the following:
  • You should not abruptly stop taking this medication, as serious problems (including a stroke or even death) may result. Your healthcare provider will advise you about how to safely stop taking Catapres. People are usually advised to slowly reduce the dose over a period of at least two to four days, with careful monitoring. Let your healthcare provider know if you develop any problems while stopping treatment.
  • Because you should not stop taking Catapres abruptly, be sure to have an adequate supply of the medication on hand at all times. Do not wait too long to refill your prescription. If you encounter any situation in which you cannot take Catapres, such as if you run out of the medication, seek the advice of your healthcare provider.
  • Some people who develop an allergic reaction to Catapres-TTS patches may also be allergic to Catapres tablets.
  • This medicine should be used with caution in people with heart disease, irregular heart rhythms, kidney problems, or who have had a heart attack or stroke.


  • People who wear contact lenses may develop problems due to dry eyes from Catapres. 


  • If you have an upcoming surgery, you may be advised to keep taking Catapres (up to four hours before the surgery) and start taking it again as soon as possible after the surgery. Be sure to ask your surgeon for specific instructions in your particular situation.
  • Catapres can potentially interact with a few other medications (see Catapres Drug Interactions).
  • This medication can cause dizziness and drowsiness, which may interfere with your ability to drive or operate heavy machinery.
  • Catapres is considered a pregnancy Category C medication. This means that it might not be safe for use during pregnancy, although the full risks are not currently known (see Clonidine and Pregnancy).
  • Catapres passes through breast milk in humans. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Clonidine and Breastfeeding).
