What Are the Dangers of Mucinex?

Mucinex is a safe, over-the-counter drug that is administered orally. When used correctly, there are very few dangers associated with this product.

Background

• Mucinex is the brand name for the drug guaifenisen, an expectorant. When taken orally, it works to thin mucus so it can be released easily from the respiratory tract.

Proper Usage

• Adults and children over 12 can take one Mucinex pill every 12 hours with a full glass of water. Pills should not be crushed; it ruins the time-release effect of the product. Consumption should not exceed 2,400 milligrams every 24 hours.

Side Effects

• Dizziness can result from taking Mucinex. Other side effects may include diarrhea, nausea, gas and headache. In general, side effects are rare and mild.

Danger

• Mucinex can lead to allergic reactions in some patients. The drug can also alter the results of some laboratory tests, so you should always tell your doctor if you have been taking it.

Effectiveness

• There is some debate about the effectiveness of Mucinex. Since a full glass of water is required with every dosage, it may be the liquid, not the drug, that helps with mucus removal.
