Warnings and precautions

• If you suffer from bronchial asthma then you should not take this medicine.
• If you have or have had a peptic ulcer, as NACSYS 600 mg effervescent tablets may irritate your gastric wall.
  In particular if you use other drugs known to irritate the gastric wall.
• There have been very rare reports of serious hypersensitivity reactions with (high) fever, skin redness, joint pains and/or eye infection (Stevens-Johnson syndrome), and acute hypersensitivity reactions accompanied by fever and blisters on the skin or peeling of the skin (Lyell syndrome) which were associated with the use of NACSYS 600 mg effervescent tablets. However, in most cases, at least one other medicine was used, which was most likely the cause for this reaction. If new changes to the skin or mucous membranes occur, you must immediately consult a doctor and stop using acetylcysteine.
• As the thick phlegm becomes more fluid, its volume will increase, especially at the beginning of the treatment. If you are unable to efficiently cough up this fluid phlegm, you must consult a doctor so that adequate measures can be taken to remove the phlegm.
• Medicines, such as NACSYS that dissolve phlegm (mucolytics) may block the airways of children under the age of 2, due to the characteristics of the airways in this age group. This may limit their ability to cough up phlegm.
  Therefore, NACSYS must not be used by children under the age of 2.
• NACSYS 600 mg effervescent tablets are not suitable for use in children and adolescent younger than 18.
• When opening the package you may perceive a mild sulfur odour (smell of rotten eggs). This is a property of the active ingredient and is normal. It does not indicate that the medicine has changed.

Consult your doctor if any of the above mentioned warnings apply to you, or have applied to you in the past.
