What can I take for sinus/head cold if I'm on Crestor and Diovan?

You can use any of the topical nasal decongestant drops or sprays that contain oxymetazoline or phenylephrine. Patients with high blood pressure should not take a systemic decongestant like Sudafed or Drixoral, they will raise your blood pressure.

EDIT: Coricidin HBP, an oral decongestant marketed to patients with high blood pressure, is safe to use but not very efficacious. I don't recommend it.

Try Coricidin HP It is especially designed for people with high blood pressure and available over the counter.
