Drug Class: Histamine Analogue | Form: Oral Tablet | Active Ingredient: Betahistine Dihydrochloride 8mg | Status: Prescription Only (Rx)
What is Serc 8mg Tablet?
Serc 8mg Tablet contains Betahistine Dihydrochloride 8mg as its active ingredient. It is a prescription medicine used to treat the symptoms of Ménière's disease — a condition that affects the inner ear and causes episodes of dizziness (vertigo), ringing in the ears (tinnitus), and partial hearing loss. Betahistine works as a histamine analogue, improving blood flow inside the inner ear, which helps reduce the build-up of fluid and pressure that causes these symptoms.
What is Serc 8mg Used For?
- Vertigo (چکر آنا) — reduces spinning dizziness and related nausea or vomiting
- Tinnitus (کانوں میں آوازیں) — helps reduce ringing or buzzing sounds in the ears
- Hearing loss associated with Ménière's disease — supports improvement in inner ear function
- Balance disorders — helps manage ongoing balance problems linked to inner ear pressure
How Does Serc 8mg Work?
Betahistine acts on histamine receptors in the inner ear. It increases blood flow through the small blood vessels of the inner ear and helps reduce the excess fluid pressure (endolymphatic pressure) that causes Ménière's symptoms. By improving circulation in this area, Serc helps reduce the frequency and severity of vertigo attacks over time with regular use.
