Frequently Asked Questions

What is guaifenesin used for?

Guaifenesin is an expectorant that helps loosen mucus in the airways, making it easier to cough up and clear chest congestion. It’s commonly found in cold and cough medications like Mucinex® and Robitussin®.

Can I take guaifenesin if I have high blood pressure?

Yes, guaifenesin is generally safe for people with high blood pressure because it does not contain decongestants like pseudoephedrine or phenylephrine, which can raise blood pressure.

What’s the difference between Mucinex and Robitussin?

Both Mucinex® and Robitussin® offer guaifenesin-based products. The main difference is that some Robitussin formulas also include dextromethorphan for cough suppression. Always check the label if you want a dextromethorphan-free option.

What cold medicine can I take without pseudoephedrine?

Look for decongestant-free options that contain only guaifenesin or cough suppressants like dextromethorphan. Products like ONCOR Liquid Guaifenesin are effective without containing pseudoephedrine.

Is saline nasal spray good for congestion?

Yes, saline sprays can help relieve nasal congestion by moisturizing and clearing nasal passages. They're drug-free and safe for daily use, but they don't treat chest congestion or cough symptoms.
