Drug Class: Histamine Analogue | Form: Oral Tablet | Active Ingredient: Betahistine Dihydrochloride 24mg | Status: Prescription Only (Rx)
What is Serc 24mg Tablet?
Serc 24mg Tablet contains Betahistine Dihydrochloride 24mg per tablet. It is a prescription medicine used to treat Ménière's disease — a disorder of the inner ear that causes recurring attacks of severe dizziness (vertigo), ringing in the ears (tinnitus), hearing loss, and nausea.
The 24mg strength is often prescribed as a convenient once or twice-daily maintenance dose, reducing the number of tablets a patient needs to take daily compared to the lower-strength formulations. Betahistine works by improving blood circulation inside the inner ear, reducing the abnormal fluid pressure that is responsible for Ménière's symptoms.
What is Serc 24mg Used For?
- Ménière's Disease (کان کی بیماری) — treats the full symptom triad: vertigo, tinnitus, and hearing loss associated with inner ear fluid pressure
- Vertigo / Dizziness (چکر آنا) — reduces the frequency and severity of vertigo attacks, including nausea and vomiting that come with them
- Tinnitus (کانوں میں آوازیں) — helps reduce persistent ringing or buzzing sounds in the ears
- Vestibular balance disorders — controls vertigo linked to inner ear balance disturbances
How Does Serc 24mg Work?
Betahistine acts on histamine H1 and H3 receptors in the inner ear. By stimulating H1 receptors, it widens the small blood vessels of the inner ear and improves local circulation. By blocking H3 receptors, it reduces excessive histamine activity that contributes to fluid accumulation.
Together, these actions lower the abnormal fluid pressure — called endolymphatic hydrops — that triggers Ménière's attacks. With regular use, Serc reduces both the intensity and how often these episodes occur.
