Table of contents:

Serc (generically known as Betahistine) is a medicine used to treat vertigo (dizziness) associated with Ménière's disease. It is a histamine analogue that is believed to manipulate the blood flow inside the inner ear, reducing the pressure on the delicate hair cells and helping to alleviate symptoms such as vertigo, tinnitus, and hearing loss.

Betahistine is used to reduce the frequency of vertigo episodes associated with Ménière's disease by reducing the pressure inside the ear. This pressure is believed to contribute to the sensation of dizziness, nausea, ringing in the ears, and hearing loss experienced by individuals with Ménière's disease.

Uses and Dosage

Serc comes in the form of tablets and is typically taken two to three times per day with or without food. If you experience an upset stomach, take it with food. Swallow the tablet with a glass of water. If needed, the score line at the center of the tablet can be used to split it in half.

To achieve the full benefits of Serc, make a dosing schedule and take it regularly. Follow the exact dosage and frequency instructions provided by your physician. Your dosage will depend on your medical condition and response to treatment. Continue taking Serc and not stop abruptly to avoid worsening conditions.

The usual recommended dosage of betahistine (Serc) for adults is 24 mg to 48 mg given in 2 or 3 divided doses. This means that the recommended starting dosage is 16 mg three times a day (48 mg daily), but your doctor may adjust the dosage based on your response to the treatment. Follow the exact dosage and frequency instructions provided by your physician to achieve the full benefits of the medication.
