Summary

N-Acetylcysteine (NAC), also known as acetylcysteine, is a versatile medication utilized for various medical purposes. Initially patented in 1960 and included in medical use in 1968, NAC is listed on the World Health Organization's essential medicines. It is employed intravenously, orally, or as an inhaled mist to address paracetamol overdose and alleviate thick mucus in chronic bronchopulmonary disorders like pneumonia and bronchitis.

NAC functions by elevating glutathione levels, a potent antioxidant neutralizing toxic paracetamol breakdown products. As a mucolytic, inhaled NAC reduces mucus thickness. In supplement form, NAC is widely taken for health and wellness, offering antioxidant, and anti-inflammatory, properties.

Clinical applications include treating drug overdose, cystic fibrosis, and chronic obstructive pulmonary disease (COPD). NAC may improve lung function during COPD exacerbations, and long-term use may alleviate chronic bronchitis symptoms and reduce the risk of exacerbations, although this effect is not consistently observed.

While N-Acetylcysteine (NAC) is generally well-tolerated, it may lead to some potential side effects. Common adverse reactions when taken orally include nausea and, occasionally, red and itchy skin. In rare instances, a non-immune type of anaphylaxis may occur. It is important to note that NAC appears to be safe during pregnancy. Additionally, when used in clinical settings or as a supplement, individuals may experience fluctuations in proinflammatory cytokine levels and oxidative stress reduction. As with any medication or supplement, individuals with pre-existing conditions or those taking other medications should consult with a healthcare professional to assess potential interactions and determine the most suitable course of use.

Dosage Recommendations
The recommended dosage of N-Acetylcysteine (NAC) can vary widely depending on the specific health concern and individual needs. Typical dosages range from 600 mg to 1800 mg per day, often divided into multiple doses. The ideal dosage may vary depending on whether it is being used for respiratory health, mental health, liver support, or as an antioxidant. To ensure safe and effective usage, it's essential to consult with a healthcare professional who can provide personalized dosing recommendations and assess any potential interactions with other medications or health conditions. Individual responses to NAC can differ, and the appropriate dosage should be determined with consideration of the specific health objectives and variations in individual needs.
