What is acetylcysteine good for?

N-acetylcysteine (NAC) is inexpensive, has very low toxicity, has been FDA approved for many years, and has the potential to improve therapeutic strategies for COVID-19. NAC administered intravenously, orally, or inhaled, may suppress SARS-CoV-2 replication and may improve outcomes if used timely.

When inhaled by mouth, acetylcysteine is used to help thin and loosen mucus in the airways due to certain lung diseases (such as emphysema, bronchitis, cystic fibrosis, pneumonia). This effect helps you to clear the mucus from your lungs so that you can breathe easier.

It works best when it is given as close to the time of overdose as possible. The more time that goes by after the overdose, the less effective the medicine will be in protecting your liver.

As a dietary supplement, NAC has been used increasingly worldwide. During this COVID-19 pandemic, NAC can potentially prevent development of critical pneumonia for the people sensitive to SARS-CoV-2 infections.

• Bronchospasm.
• Disagreeable odor.
• Drowsiness.
• Fever.
• Coughing up blood.
• Increased volume of bronchial secretions.
• Irritation of tracheal or bronchial tract.
• Nausea.

Acetylcysteine inhalation solution can make you drowsy. It can also cause other side effects.

For oral use. Swallow the capsule with a drink of water. The capsule should be taken after food. In patients with impaired kidney or liver function there is insufficient data on whether dosage adjustments are required.

Criteria for Discontinuing NAC: At the end of the 21 hr protocol, NAC may be discontinued if the following criteria are met: Negative acetaminophen level, INR less than or equal to 1.5, AST or ALT less than 50 IU/L OR, if elevated, declining and less than 50% of the peak value measured.

N-acetyl cysteine is an FDA-approved prescription drug. It can cause side effects such as dry mouth, nausea, vomiting, and diarrhea.

When inhaled, it can cause swelling in the mouth, runny nose, drowsiness and chest tightness. People with bleeding disorders or taking blood thinning medications should not take NAC, as it may slow blood clotting ( 48 ).

Twice daily administration or three times daily administration is commonly recommended by the manufactures. There is no recommended daily allowance for NAC, because unlike vitamins, it’s not an essential nutrient. The dosage used to prevent radio contrast dye damage is 600 mg to 1200 mg every 12 hours for 48 hours.

NAC (N-acetyl cysteine) helps break down mucus. For that reason, inhaled NAC is used in hospitals to treat bronchitis. NAC may also protect lung tissue through its antioxidant activity.

Pharmacologic treatments for impaired mucous secretion clearance include agents such as isotonic saline, hypertonic saline, dornase alpha, and acetylcysteine (also known as N-acetylcysteine [NAC]). NAC hydrolyzes the disulfide bonds of mucus proteins to decrease mucus viscosity, thereby facilitating its clearance.

The FDA claims that there’s no evidence that NAC was used as a supplement prior to its use as a drug – so including NAC in a supplement makes the product an unapproved drug and thus illegal.

A form of cysteine called L-cysteine may help treat arthritis and hardening of the arteries. It may help treat certain lung diseases. These include bronchitis, emphysema, and tuberculosis.

N-acetylcysteine (NAC) may offer renal and hepatic protection during surgery, but in experimental studies it has been shown to impair coagulation. Since very little is known about the effects of NAC on blood coagulation in surgical patients, we studied its effects during abdominal aortic reconstruction.

Oral administration of acetylcysteine, especially in the large doses needed to treat acetaminophen overdose, may result in nausea, vomiting and other gastrointestinal symptoms. Rash with or without mild fever has been observed rarely.

Acetylcysteine is indicated for use as a mucolytic in respiratory disorders such as in bronchitis, emphysema, mucoviscidoses and bronchiectasis. NACSYS 600 mg effervescent tablets is indicated in adults only. 1 effervescent tablet of 600 mg once daily.

Thus, we conclude that concomitant oral dosing with APAP and NAC can provide a convenient and effective way of preventing toxicity associated with large dosage of APAP.

Co-administration of NAC with APAP can improve the antinociceptive effect of APAP. It is suggested that this compound can enhance analgesic effects of APAP and eventually lead to a reduction in acetaminophen dose. Further studies are needed to evaluate the molecular mechanism of this hyper analgesic effect.

A blood level of acetaminophen in the range of 10 to 20 mcg/mL is considered safe. A blood level of acetaminophen higher than 200 mcg/mL 4 hours after ingestion means there is risk for liver damage.

NAC is known to cause adverse effects in up to 10% of patients, including anaphylactoid reactions such as hypotension, tachycardia, bronchospasm and respiratory distress.

Acetylcysteine is in a class of medications called mucolytic agents. It works by thinning the mucus in the air passages to make it easier to cough up the mucus and clear the airways.

A comprehensive study will shed light on the underlying biological mechanism linking cysteine to obesity. People with high levels of the amino acid cysteine carry 6-10 kilograms more fat than other people.

NAC is a precursor to L-cysteine which is vital in replenishing levels of glutathione, an incredibly important antioxidant. L-cysteine is available through foods like animal proteins and legumes, but there are differences between the two amino acids. NAC independently is also an antioxidant.

Results. A significant skin lightening was observed after 12 weeks of oral supplementation with L-Cystine associated with L-Glutathione. This combination also induced a significant reduction in the size of facial dark spots after 6 and 12 weeks.

Interactions between your drugs No interactions were found between NAC and Vitamin C.

Studies using dietary supplementation of the cysteine analogue N-acetylcysteine (NAC) have shown that, overall, it prevents or attenuates increased blood pressure in animal models of hypertension (22–33).

Improves Lung Health NAC is also useful to help fight long-term lung damage in those with chronic obstructive pulmonary disease (COPD) (8).
