What are Serc tablets?
Serc tablets are a treatment for conditions that cause vestibular vertigo, like Ménière's disease, benign paroxysmal positional vertigo (BPPV), labyrinthitis and vestibular neuritis. It reduces vertigo, as well as linked symptoms like nausea, hearing problems and tinnitus.
Ménière's disease, BPPV, labyrinthitis and vestibular neuritis are all problems with the inner ear that can cause vertigo. Vertigo is a sensation of overwhelming dizziness that throws you off balance. You take Serc tablets a few times a day and they help you prevent and manage attacks of vertigo.
How do Serc tablets work?
The active ingredient in Serc is betahistine dihydrochloride. This is a type of medication called a histamine antagonist. That means it works by binding to the histamine receptors in the brain. This then dilates the blood vessels in the inner ear, helping to ease vertigo symptoms.
Histamine antagonists also seem to help the symptoms of Ménière's disease, BPPV, labyrinthitis and vestibular neuritis overall. This may be due to its effects on the central nervous system, where it has a slightly sedating effect.
What doses of Serc tablets are there?
Serc tablets come in two sizes, an 8mg dose and a 16mg dose. How often you take it will depend on how severe your symptoms are and how you respond to treatment. The usual starting dose is 16mg three times a day, but you might take more or less depending on how this goes. Sometimes people find a lower dose suits them better, while other people find the starting dose is perfect.
