1. What Flumil 100 mg/ml is and what it is used for
Flumil 100 mg/ml contains the active ingredient acetylcysteine, which belongs to a group of medicines called mucolytics that reduce the viscosity of mucus, making it more fluid and easier to eliminate from the respiratory tract.
Flumil 100 mg/ml is indicated to facilitate the elimination of excess mucus and phlegm in adults and children from 2 years of age, in respiratory processes with bronchial hypersecretion such as: acute and chronic bronchitis, chronic obstructive pulmonary disease (COPD), emphysema, pulmonary complications of cystic fibrosis, facilitation of maneuvers in anesthesia for bronchoscopies, bronchographies, and bronchoaspiration, bronchiectasis, obstructive and infectious complications due to tracheotomy and bronchopulmonary due to surgical intervention.
2. What you need to know before taking Flumil 100 mg/ml
Do not use Flumil 100 mg/ml:
- If you are allergic to the active ingredient or 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 use Flumil 100 mg/ml.
If you have asthma or a severe respiratory disease, you should consult your doctor before taking this medicine, as it may cause respiratory difficulties (bronchospasm).
Patients with bronchial asthma should be closely monitored during treatment. If bronchospasm occurs, acetylcysteine should be discontinued immediately and appropriate treatment initiated. This bronchoconstrictor effect can be prevented by prior administration of a bronchodilator.
The possible sulfurous odor (like rotten eggs) of the medicine is characteristic of the active ingredient, but it does not indicate that its characteristics have been altered.
Caution is recommended when using the product in patients with peptic ulcer or history of peptic ulcer, especially in cases of concomitant administration of other medicines with a known irritating effect on the gastric mucosa.
During the first days of treatment, you may observe an increase in mucus and phlegm, which will decrease throughout the treatment. If you see that you are not able to expectorate effectively, postural drainage and bronchoaspiration should be performed.
Intravenous administration will be carried out under strict medical supervision. It is more likely that adverse reactions will appear after intravenous perfusion if the drug is administered too quickly or in excess. Therefore, it is recommended to strictly follow the instructions that appear in section 3. How to use Flumil 100 mg/ml.
Acetylcysteine is not compatible with rubber and certain metals, especially iron, nickel, and copper. Contact with materials containing them should be avoided.
It should be administered with caution in long-term treatment in patients with histamine intolerance.
Children and Adolescents
In children and adolescents, the same precautions and warnings apply.
It is contraindicated in children under 2 years of age.
Other Medicines and Flumil 100 mg/ml
Tell your doctor or pharmacist if you are using, have recently used, or may need to use any other medicine.
In case you need simultaneous treatment with nitroglycerin, you should monitor the appearance of hypotension (low blood pressure), which can be severe, and may cause headache.
The simultaneous use of carbamazepine, a drug used to combat epilepsy attacks, may increase the risk of attacks.
Do not administer concomitantly with antitussive medicines (for cough) or with those that decrease bronchial secretions (such as antihistamines and anticholinergics), as it may lead to accumulation of bronchial secretions.
Administration of antibiotics is recommended separately.
It is not recommended to dissolve Flumil 100 mg/ml with other medicines.
Using Flumil 100 mg/ml with Food and Drinks
Taking food and drinks does not affect the efficacy of this medicine.

Acetylcysteine crosses the placenta. Therefore, the use of acetylcysteine during pregnancy is not recommended.
It is unknown whether acetylcysteine and its metabolites are excreted in breast milk. Its use during breastfeeding should be avoided.
No data are available on the effect of acetylcysteine on human fertility. Animal studies do not indicate harmful effects on human fertility at recommended doses.
