Fluimucil: Uses, Mechanism of Action, Dosage, Side Effects, Interactions

What is Fluimucil?

Fluimucil is a brand of N-Acetylcysteine. It is a mucolytic medication used in combination with other treatments to relieve chest congestion due to thick or abnormal mucous secretions in people with lung conditions including asthma, emphysema, bronchitis, and cystic fibrosis (an inborn disease that causes problems with breathing, digestion, and reproduction).

This effect helps you to clear the mucus from your lungs so that you can breathe easier. It can also be used to prevent liver damage from paracetamol (acetaminophen) overdose.

Each Fluimucil effervescent tablet contains N-acetylcysteine, 600 mg as an active ingredient while each sachet of Fluimucil contains N-acetylcysteine, 100 mg or 200mg as the active ingredient. Each 5ml of Fluimucil oral solution contains 100mg of N-acetylcysteine.
