Warnings and Precautions

  • There is a risk of myocardial infarction in the event of a sudden cessation of therapy, so it may only be discontinued gradually.
  • Before anesthesia, the doctor should be informed about the intake.
  • Diabetics should check their blood sugar levels frequently, and the signs of hypoglycaemia can no longer be recognized as such (obfuscation).
  • Contact lens wearers should keep in mind that lessening of tears may occur.
  • Regular medical checks are required. Treatment should be given to an experienced physician (internist, cardiologist).
  • At baseline, worsening of the heart (especially increased fluid retention) is possible.
  • If the heartbeat slows down, the doctor should reduce the dose.
  • The drug is on the Doping List and should not be used during sports competitions.
  • The ability to drive or operate machinery may be impaired. This applies to a greater extent at the beginning of treatment and in conjunction with alcohol.

Sometimes medications release allergic reactions.
If you notice signs of allergic reaction, tell your doctor or pharmacist immediately.
