How should I take acetylcysteine (Mucomyst-10)?

Use this medication exactly as it was prescribed for you. Do not use the medication in larger amounts, or use it for longer than recommended by your doctor. Follow the instructions on your prescription label.

Acetylcysteine liquid may change color once you have opened the bottle. This is caused by a chemical reaction and will not affect the medicine.

Do not use acetylcysteine at home if you do not fully understand all instructions that are specific to your use of this medication. Use only the inhaler device provided with your medicine or you may not get the correct dose.

Do not mix your dose of acetylcysteine until you are ready to use the medication. Diluted acetylcysteine must be used within 1 hour of mixing.

Acetylcysteine solution can be inhaled directly from the nebulizer, or with a face mask, mouth piece, tent, or intermittent positive pressure breathing (IPPB) machine.

The Mucomyst brand of acetylcysteine should not be placed directly in a heated nebulizer.

Clean your nebulizer right after each use. The residue from acetylcysteine can clog the parts of the nebulizer.

Store an unopened vial (bottle) of acetylcysteine at room temperature, away from moisture and heat.

Diluted acetylcystine may also be stored in a refrigerator, but you must use it within 96 hours (4 days) after mixing. Do not allow the medication to freeze.
