About this active substance

The combination of guaifenesin and phenylephrine is used to relieve cold and flu symptoms, including nasal congestion and productive cough. It combines an expectorant with a nasal decongestant.

Guaifenesin helps thin mucus, making it easier to expel, while phenylephrine reduces nasal congestion by constricting blood vessels in the nasal lining.

This combination is generally well-tolerated but may cause side effects such as dizziness, nausea, insomnia, or increased blood pressure. In rare cases, allergic reactions may occur.

It is important to follow the dosage instructions and avoid long-term use without a doctor's recommendation. Consult a specialist if symptoms persist or worsen.
