Guaifenesin With Cetirizine
There is no drug interaction between them.
Can I take Mucinex with the allergy medication Zyrtec?
It is safe to take cetirizine (active ingredient in Zyrtec) and Guaifenesin (active ingredient in Mucinex) together. There is no interaction between them.
In fact, it is fairly common to take the combination as they each help to treat different symptoms.
Cetirizine, a 'second-generation' antihistamine, is effective for treating many of the symptoms we associate with allergies or colds, including:
- Runny nose
- Watery eyes
Guaifenesin is an expectorant, helping to clear chest congestion and thin mucus secretions.
Cetirizine and guaifenesin can have synergistic effects.
Cetirizine can help to 'dry' mucus secretions, due to the anticholinergic effects of the drug. This can aid in reducing or helping to expectorate thick mucus that feels as though it is 'stuck' in your chest and airway.
Guaifenesin is generally very well tolerated and has few side effects or interactions. Nausea, drowsiness, dizziness, and headache occur rarely at recommended doses of guaifenesin.
Cetirizine may cause drowsiness in some individuals, but this effect should not be exacerbated by the addition of guaifenesin.
There is no interaction between guaifenesin and cetirizine. They are safe to take together.
