Mucinex and ibuprofen: the short version
- They're safe to pair for most people. Guaifenesin, the medicine in plain Mucinex, has no known interaction with ibuprofen.
- Take them together or apart. There's no gap needed between a Mucinex dose and an ibuprofen dose.
- No Mucinex contains ibuprofen or aspirin. But Fast-Max and Sinus-Max boxes do contain acetaminophen (the same thing as Tylenol).
- Water makes Mucinex work better. A full glass with each dose helps loosen the mucus.
- Check with a pharmacist first if you have high blood pressure, ulcers, kidney or heart disease, take a blood thinner, or are pregnant.

Do you need to space out Mucinex and ibuprofen?

Common questions
Can you take Mucinex with ibuprofen?
Yes, for most healthy adults. Plain Mucinex and Mucinex DM don’t contain a pain reliever, so ibuprofen doesn’t double anything up. Check your box first: some multi-symptom Mucinex products contain acetaminophen or a decongestant.
What pain reliever is safe to take with Mucinex?
With plain Mucinex or Mucinex DM, ibuprofen (Advil, Motrin) or acetaminophen (Tylenol) both work. If your Mucinex already has acetaminophen in it, use ibuprofen instead of Tylenol.
Does Mucinex have aspirin or ibuprofen in it?
No. Mucinex products don’t contain aspirin or ibuprofen. Some multi-symptom boxes, like Fast-Max and Sinus-Max, contain acetaminophen, the pain reliever in Tylenol.
What medications should not be taken with Mucinex?
Don’t take Mucinex DM with an MAOI antidepressant or within 2 weeks of stopping one. Don’t stack two cold medicines with the same ingredients, two decongestants, or two acetaminophen products. Ask a pharmacist about anything else you take.
Can you take Mucinex with 800 mg ibuprofen?
800 mg ibuprofen is a prescription dose. Plain Mucinex doesn’t interact with it, but ask the doctor or pharmacist who prescribed it before adding any cold medicine.
Can I take Mucinex and ibuprofen while breastfeeding?
Ask your doctor or pharmacist first. They can check the exact products and doses for you and your baby.
Can kids take children’s Mucinex with ibuprofen?
Ask a pediatrician or pharmacist first. Children’s doses go by age and weight, and some children’s Mucinex products contain more than one active ingredient.
