This combination includes a mucolytic (guaifenesin), a menthol (levomenthol), and an antihistamine (diphenhydramine). It helps in managing cough, congestion, and other cold symptoms by addressing different aspects of respiratory discomfort.

Uses

This combination medication is used to:

Mechanism of Action

The individual components of this combination work through different mechanisms:

Guaifenesin: Acts as an expectorant by increasing the volume and reducing the viscosity of secretions in the airways, facilitating easier clearance.
Levomenthol: Provides a local cooling sensation and can help relieve nasal congestion by stimulating sensory receptors in the nasal passages.
Diphenhydramine: Blocks histamine H1 receptors to reduce allergic symptoms such as itching, sneezing, and runny nose.

The combination addresses multiple symptoms of respiratory discomfort simultaneously.

How Long Does It Take to Work?

Relief of symptoms may begin within 30 minutes to 1 hour after administration. The onset of action can vary depending on the individual’s response and the specific symptoms being treated. Full symptom relief may take several doses over a period of time, typically aligning with the product's dosing schedule.

Absorption

After oral administration, guaifenesin, levomenthol, and diphenhydramine are absorbed from the gastrointestinal tract. The onset of action for each component may vary, but they generally start to work within an hour of ingestion.

Route of Elimination

Guaifenesin is primarily excreted in the urine. Levomenthol is metabolized in the liver and also excreted through the urine. Diphenhydramine is metabolized in the liver and excreted in the urine. The rate of elimination can be affected by liver and kidney function.
