# TUSQ
## Overview
TUSQ (pronounced "tus-cue") is a brand name for guaifenesin, an expectorant. It is thought to work by increasing the volume and reducing the viscosity of secretions in the trachea and bronchi, thereby facilitating their removal by coughing.
## Primary Indications
* Symptomatic relief of cough associated with the common cold, bronchitis, or other respiratory conditions.
* Aids in loosening mucus.
## Adult Dosing
* **Immediate-release formulations:** 200-400 mg every 4 hours as needed.
* **Extended-release formulations:** 600-1200 mg every 12 hours as needed.
* Maximum dose is generally 2400 mg per day for extended-release.
## Pediatric Dosing
Dosing for children varies by age and product formulation. Always refer to the specific product labeling or consult a pediatrician.
* **Children 6-11 years:** 100-200 mg every 4 hours as needed. Maximum 1200 mg per day.
* **Children 2-5 years:** 50-100 mg every 4 hours as needed. Maximum 600 mg per day.
* **Children under 2 years:** Consult a pediatrician. Dosing is not well-established and use should be cautious.
## Dose Adjustments
No specific dose adjustments are generally required for hepatic or renal impairment, though caution may be advised in severe disease.
## Contraindications
* Hypersensitivity to guaifenesin or any component of the formulation.
## Adverse Effects
* Nausea
* Vomiting
* Dizziness
* Headache
* Rash
## Key Drug Interactions
* No significant drug interactions are well-established.
## Monitoring
* Monitor for improvement of cough symptoms.
* Monitor for adverse effects.
## Clinical Pearls
* TUSQ is intended for symptomatic relief and does not treat the underlying cause of the cough.
* Adequate hydration may enhance the effectiveness of guaifenesin.
* Extended-release formulations provide longer-lasting relief.
