Stahist AD is used to temporarily relieve symptoms associated with the common cold, seasonal allergies, and hay fever, including nasal congestion, sinus congestion, runny nose, sneezing, itchy nose or throat, and watery eyes.
Stahist AD contains a combination of an antihistamine (typically chlorpheniramine) and a decongestant (typically phenylephrine). The antihistamine blocks histamine to reduce allergic symptoms like sneezing and itching, while the decongestant constricts blood vessels in the nasal passages to reduce swelling and congestion.
This medication may cause drowsiness and should be used with caution when operating machinery or driving. Patients with certain conditions such as high blood pressure, heart disease, thyroid disorders, diabetes, or glaucoma should consult a healthcare provider before use. It is not recommended for use in children under a certain age, and alcohol may enhance sedative effects. Patients should avoid taking multiple products containing similar ingredients to prevent overdose.
