Betahistine dihydrochloride is a medication used to treat vertigo, a type of dizziness characterized by a spinning or whirling sensation. Betahistine is thought to work by improving blood flow to the inner ear, which can help to reduce the symptoms of vertigo.
Betahistine is available in tablet form and is typically taken three times a day with meals. The recommended dosage may vary depending on the severity of the patient's symptoms and other factors, such as their age and overall health.
Like all medications, Betahistine may cause side effects in some people. Some common side effects of Betahistine include headache, nausea, and stomach upset. In rare cases, Betahistine may cause more serious side effects, such as difficulty breathing, chest pain, or an allergic reaction. If you experience any severe or persistent side effects while taking Betahistine, it is important to contact your healthcare provider immediately.
