1. What Betahistina Normon is and what it is used for

Betahistina Normon belongs to a group of medicines called antivertigo medicines, and its active ingredient is betahistina dihydrochloride.

Betahistina is used to treat Meniere's Syndrome, which is a disorder characterized by the following symptoms: vertigo (with nausea and vomiting), hearing loss, and a sensation of noise in the ear (tinnitus).

The active ingredient of this medicine is a histamine analogue that acts by improving circulation in the inner ear, thereby reducing pressure. The inner ear is one of the organs responsible for the sense of balance.

Follow exactly the administration instructions of this medicine given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

Your doctor will adjust the dose based on your response to treatment, from an initial dose of half a 16 mg tablet three times a day to a 16 mg tablet three times a day (maximum dose). The maintenance dose will be adjusted based on your response, being the minimum effective dose, half a 16 mg tablet three times a day.

The tablets should be taken with water. The 16 mg tablets are scored to allow them to be divided into two equal halves and facilitate the administration of half the dose (8 mg) when necessary.

In some cases, the improvement may not begin to become apparent until two weeks after the start of treatment. The optimal result is obtained after several months of treatment.
