Molecule Description
Betahistine is commonly used to treat Ménière’s disease and other vestibular disorders that affect the inner ear. It helps relieve troubling symptoms such as vertigo, dizziness, tinnitus (ringing in the ears), hearing disturbances, and imbalance. Betahistine works by improving microcirculation in the inner ear and reducing excessive pressure within the labyrinth, which helps restore natural balance signals and provides sustained symptomatic relief.
Your doctor will prescribe Betahistine in a dose and duration tailored to your condition. It is important to take the medicine exactly as directed, preferably at the same time each day to maintain steady therapeutic levels. Do not increase, decrease, or stop the medication on your own, even if symptoms improve, unless advised by your healthcare provider.
Betahistine may cause mild and temporary side effects such as nausea, headache, bloating, or indigestion. These effects often settle as the body adapts to the treatment. However, if side effects persist, worsen, or interfere with daily activities, you should follow up with your doctor for further evaluation or dose adjustments.
Before starting Betahistine, inform your doctor if you are pregnant, planning pregnancy, or breastfeeding, as medical guidance may be required. You should also share your complete medical history, especially if you have asthma, peptic ulcers, or low blood pressure, in addition to a list of all medicines or supplements you are currently taking.
