Can I take guaifenesin 400 mg/phenylephrine HCl 10 mg safely with these meds Plaquenil, Cymbalta, Vyvanse, Omeprazole, ambien Linzess, Valium Celebrex

Can I take guaifenesin 400 mg/phenylephrine HCl 10 mg safely with these meds Plaquenil, Cymbalta, Vyvanse, Omeprazole, ambien Linzess, Valium Celebrex

Other than that you're fine. ...Read more

Decongestant- phenylephrine. Bp med - inderal. Antidepressants- Zoloft and wellbutrin (bupropion). And synthroid. I had asked the? About decongestant dosage

Decongestant: We need all the pertinent info together in one question since these questions do not appear sequentially. There are several drug interactions among the current meds. Decongestants interact with BP meds like Inderal (propranolol) & lessen their effect, resulting (possibly) in higher blood pressure. Your pcp can determine what dose will least effect BP & still produce the desired decongesting effect. ...Read more
