Guaifenesin is an expectorant available in the Philippines that helps loosen mucus in the airways, making coughs more productive [1]. It is commonly found in over-the-counter (OTC) medications used to treat cold and cough symptoms [2].
How does guaifenesin work?
Guaifenesin is thought to work by increasing the volume and reducing the viscosity of secretions in the trachea and bronchi [3]. This action thins mucus, making it easier to expel from the lungs through coughing [3].
What conditions is guaifenesin used for?
Guaifenesin is primarily used to provide temporary relief from cough associated with the common cold, bronchitis, and other respiratory conditions [1][3]. It is not intended to suppress the cough reflex but rather to facilitate mucus clearance [3].
How is guaifenesin sold in the Philippines?
In the Philippines, guaifenesin is available in various formulations, including tablets, capsules, and liquid syrups, often in combination with other active ingredients like dextromethorphan or decongestants [2]. It is widely distributed by pharmaceutical companies and available in drugstores and pharmacies nationwide [2].
Are there any specific brands of guaifenesin in the Philippines?
Several brands of guaifenesin products are marketed in the Philippines. Some examples include Robitussin, Mectan, and Pedia C-Z [2]. The availability of specific brands may vary by retailer.
What are the side effects of guaifenesin?
Common side effects of guaifenesin can include dizziness, headache, nausea, vomiting, and stomach pain [3]. While generally well-tolerated, it is important to follow dosage instructions and consult a healthcare professional if adverse reactions occur [3].
