Microser (Betahistine Dihydrochloride)

Betahistine acts as a histamine H1 receptor agonist and an H3 receptor antagonist. This dual activity increases histamine release in the inner ear, causing vasodilation of the stria vascularis, enhancing microcirculation, and reducing vestibular hyperexcitability, which collectively lessen vertigo symptoms.

The appropriate dose of Microser is determined by the prescribing clinician based on the patient’s condition, age, and response to therapy. Healthcare professionals tailor the regimen to achieve optimal symptom control while monitoring for tolerability.

Safety data for betahistine during pregnancy and lactation are limited. It is classified as a category where risk cannot be ruled out, so clinicians should evaluate the potential benefits against possible risks before prescribing to pregnant or nursing individuals.

To request Microser, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Compared with diuretic‑based therapies such as acetazolamide or loop diuretics, betahistine primarily improves inner‑ear microcirculation rather than reducing fluid volume. It generally has a more favourable side‑effect profile, but efficacy may vary, and some clinicians combine it with diuretics for refractory cases.

Microser tablets should be stored at ambient temperature, preferably below 25 °C. Keep them in the original blister pack, protect from moisture and direct sunlight, and ensure the container is tightly closed to maintain product stability.

Microser is taken orally, usually with or without food, as directed by a healthcare professional. The tablets are swallowed whole with a glass of water and should not be crushed or chewed unless specifically advised by the prescriber.

Serious adverse reactions, although rare, include significant hypotension, severe allergic responses such as anaphylaxis, and cardiac arrhythmias. Patients should seek immediate medical attention if they experience sudden drops in blood pressure, difficulty breathing, swelling of the face or throat, or irregular heartbeats.

Microser is contraindicated in individuals with known hypersensitivity to betahistine or any excipients in the tablet. Caution is advised for patients with uncontrolled hypertension, severe cardiovascular disease, or those taking monoamine oxidase inhibitors, as the combination may increase the risk of adverse events.
