Generic Name: diphenhydramine/pseudoephedrine (DYE-fen-HYE-dra-meen/SOO-doe-e-FED-rin)
Brand Name: Respa SA
Respa SA is used for:
Relieving symptoms of sinus congestion, pressure, runny nose, and sneezing due to colds, upper respiratory infections, and allergies. It may also be used for other conditions as determined by your doctor.
Respa SA is an antihistamine and decongestant combination. The antihistamine works by blocking the action of histamine, which helps reduce symptoms such as watery eyes and sneezing. The decongestant promotes sinus and nasal drainage, which relieves congestion and pressure.

- you have severe high blood pressure, severe heart blood vessel disease, fast heartbeat, severe heart problems, narrow-angle glaucoma, or if you are unable to urinate
- you are taking sodium oxybate (GHB) or you have taken furazolidone or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) within the last 14 days
Contact your doctor or health care provider right away if any of these apply to you.
