General information:

This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if their signs of illness are the same as yours.

If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet.

If you forget to take Acetyl cysteine, do not take a double dose to make up for a forgotten dose. Take your tablet as soon as you remember, unless it is almost time for your next dose. If it is almost time for your next dose, then just take the next dose as usual.

Mechanism of Action:

Mucolytic effects:

As a mucolytic, it is believed that the free sulfhydryl groups in acetylcysteine react with the disulfide linkages of mucoproteins in bronchial secretions. This, in turn, acts to decrease the hypersecretion and viscosity of mucus secretions of the lungs and aids in the removal of these secretions through coughing, mechanical mechanisms, or postural drainage.

Antioxidant effects:

Antioxidants such as acetylcysteine may prevent tissue damage to various organs by scavenging oxygen free radicals (e.g., superoxides) or by other poorly understood mechanisms, such as stabilization of cellular signal transduction systems and reduced apoptosis (programmed cell death).

Indications and Dosage:

Reduction of sputum viscosity: 

Adult: 600 mg once daily


Hypersensitivity to the active substance or to any of the excipients.

  • Bronchial asthma
  • Cough relieving medicines (antitussives) used in combination with acetylcysteine can cause a dangerous build-up of secretions.
