Acetylcysteine, also known as N-acetylcysteine (NAC), is a medication that is used to treat

fibrosis or chronic obstructive pulmonary disease. It can be taken intravenously, by mouth,

Common side effects include nausea and vomiting when taken by mouth.The skin may
occasionally become red and itchy with either form. A non-immune type of anaphylaxis
may also occur. It appears to be safe in pregnancy. For paracetamol overdose, it works by
increasing the level of glutathione, an antioxidant that can neutralise the toxic breakdown
products of paracetamol. When inhaled, it acts as a mucolytic by decreasing the thickness
of mucus.
Acetylcysteine was initially patented in 1960 and came into medical use in 1968. It is on the
World Health Organization's List of Essential Medicines, which lists the safest and most
effective medicines needed in a health system. It is available as a generic medication and

bronchial mucus.
3. N-acetyl-cysteine can boost glutathione levels in cells.
4. N-Acetyl-L-Cysteine is a conditionally essential amino acid, one of only three sulfur-
containing amino acids, the others being taurine (which can be produced from L-cysteine)
and L-methionine from which L-cysteine can be produced in the body by a multi-step process.
5. N-Acetyl-L-Cysteine can act as an antioxidant, may prevent liver diseases, and can help
to thicken the individual diameters of existing hair if taken regularly.
