1. What Acetilcisteína Viatris is and what it is used for

Acetylcysteine, the active substance of this medicine, belongs to a group of medicines called mucolytics.

Acetilcisteína Viatris is used to liquefy excessive and/or thick bronchial secretions. It is indicated as supportive treatment in respiratory conditions associated with hypersecretion, excessive or thick mucus, such as:

• Acute and chronic bronchitis (inflammation of the bronchi).

• Chronic Obstructive Pulmonary Disease (COPD).

• Emphysema (inflammation of the lung alveoli, leading to reduced respiratory function).

• Atelectasis (reduction in lung volume) due to mucus obstruction: pulmonary complications of cystic fibrosis and other related conditions.

2. What you need to know before taking Acetylcysteine Viatris

Do not take Acetylcysteine Viatris:

• If you are allergic to acetylcysteine and its derivatives, or to any of the other components of this medicine (listed in section 6).
• Do not administer to children under 2 years of age.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Acetylcysteine Viatris.

• If you have asthma or suffer from a serious respiratory disease, you should consult your doctor before taking this medicine.
• The possible sulfur-like odor (resembling rotten eggs) of the medicine is characteristic of the active substance and does not indicate that the medicine is in poor condition.
• If you experience stomach discomfort while taking the medicine, stop treatment and consult your doctor or pharmacist. Caution is advised in patients with peptic ulcer or history of peptic ulcer.
• During the first few days of treatment, you may notice an increase in mucus and phlegm, which will gradually decrease over the course of treatment.

Children and adolescents

Other medicines and Acetylcysteine Viatris

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

• Concomitant therapy with nitroglycerin may cause headache, and hypotension—which may be severe—should be monitored.
• Concomitant administration with the antiepileptic carbamazepine may reduce the effectiveness of carbamazepine.
• Do not take together with antitussive medicines (for cough) or those that reduce bronchial secretions (such as antihistamines and anticholinergics), as this may lead to accumulation of liquefied mucus.
• When taking medicines containing minerals such as iron or calcium, or medicines containing antibiotics such as amphotericin B, sodium ampicillin, cephalosporins, lactobionate, erythromycin, and certain tetracyclines, separate their administration from that of Acetylcysteine by at least 2 hours.

Dissolving acetylcysteine with other medicines is not recommended.
