S-T Forte 2 liquid

Generic Name: chlorpheniramine/hydrocodone (KLOR-fen-IR-a-meen/HYE-droe-KOE-done)
Brand Name: Vituz

S-T Forte 2 liquid is used for:

Relieving cough and symptoms of the common cold or upper respiratory allergies. S-T Forte 2 liquid may also be used for other conditions as determined by your doctor.

S-T Forte 2 liquid is a narcotic antitussive (cough suppressant) and antihistamine combination. The antitussive works by suppressing the cough center in the brain. The antihistamine works by blocking the action of histamine and reduces the symptoms of an allergic reaction such as itch, watery eyes, and runny nose.

Do NOT use S-T Forte 2 liquid if:

  • you are allergic to any ingredient in S-T Forte 2 liquid
  • you have narrow-angle glaucoma, severe high blood pressure, severe heart blood vessel disease, or if you are unable to urinate
  • you are taking sodium oxybate (GHB) or if you have taken 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.
