Hi i took zyrtec and mucinex (guaifenesin) earlier. can i take a sudafed as well?

Mgt: I would advise against taking an additional medication. Nasal rinses and nasal steroids may relieve your symptoms. A virtual appointment may be scheduled.

Yes: Should be fine - consider multi-ingredient cold medicines. But you are wise to ask the question. For example, different over the counter meds contain Tylenol (acetaminophen) and you risk getting too much of the drug by taking combinations.
