Rindal HPD syrup

Generic Name: diphenhydramine/hydrocodone/phenylephrine (dye-fen-HYE-dra-meen/high-droe-KOE-dohn/fen-ill-EF-rin)
Brand Name: Hydro-DP and Rindal HPD

Rindal HPD syrup is used for:

Relieving congestion and cough and preventing or treating symptoms such as runny nose, sneezing, itching of the nose and throat, and itchy, watery eyes due to colds, flu, or hay fever. It may also be used for other conditions as determined by your doctor.

Rindal HPD syrup is an antihistamine, decongestant, and cough suppressant combination. It works by constricting blood vessels and reducing swelling in the nasal passages, allowing you to breathe more easily. The antihistamine works by blocking the action of histamine, reducing symptoms of an allergic reaction. The cough suppressant works in the brain to decrease the cough reflex to help decrease a dry cough.

Do NOT use Rindal HPD syrup if:

  • you are allergic to any ingredient in Rindal HPD syrup
  • you have had a severe allergic reaction (eg, severe rash, hives, difficulty breathing, dizziness) to morphine, codeine, or any other opiate (eg, hydrocodone, dihydrocodeine, oxycodone)
  • you have severe high blood pressure, rapid heartbeat, or other severe heart problems (eg, heart blood vessel disease)
  • you take 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.
