mucolytic agents

Mucus may narrow or block the airways, making it difficult to breath. Mucolytic drugs are designed to help loosen and clear the mucus from the airways by breaking up the sputum. The most common type of mucolytic is a medication called N-acetylcysteine. This medication is available in tablet or inhaled form. The inhaled form is given by a nebulizer. N-acetylcysteine is more commonly used by patients in European countries than in patients in the USA.

What problems (side-effects) should I watch for with mucolytic agents?

The liquid solutions such as mucomyst can cause breathing spasms, nausea and rashes. The tablets can cause nausea and diarrhea.

How often and how much should I take?

The amount prescribed will vary on your need. It is important to discuss the usefulness of dose of the mucolytic agent

with your healthcare provider. You may be the best judge of this since you’ll know if the medication is making the mucus easier to cough out or not.

Find out from the pharmacist the type of tablet you are taking. Some tablets must be dissolved before use (bronkyl, mucomyst) while others can be swallowed whole. Likewise, some liquid solutions (mucomyst) must be nebulized in a device, while other liquid solutions can be swallowed in tablet or liquid form (guiafenesin).

What should I do if I forget to take my mucolytic agents?

If you forget to take your mucolytic agent, you may take the medication when you remember and then resume your usual schedule. It is not critical if you miss a dose.
