Betahistina Normon 16 mg TabletsEFG
Betahistina Dihydrochloride
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.
Do not take Betahistina Normon
Consult your doctor or pharmacist before starting to take betahistina:
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including those obtained without a prescription.
Taking Betahistina Normon at the same time as antiallergic medicines such as antihistamines (especially H1 antagonists) may reduce the efficacy of both medicines.
Taking Betahistina Normon at the same time as monoamine oxidase inhibitors (MAOIs) (used to treat Parkinson's disease) may increase the effect of Betahistina Normon.
It is recommended to take Betahistina Normon during or after meals to avoid stomach upset.
Children and Adolescents
Betahistina Normon is not recommended for use in children and adolescents under 18 years of age due to the lack of data on safety and efficacy.
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

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.
The tablets can be taken with or without food. However, if taken in the absence of food, they may cause mild stomach problems (listed in section 4). Taking the tablets with food may help reduce stomach problems.
Betahistina is not recommended for use in children and adolescents under 18 years of age due to the lack of data on safety and efficacy.

Symptomatic treatment is recommended since there is no specific antidote.
Do not take a double dose to make up for forgotten doses. If you forget to take a dose, wait until the next dose and continue with the normal treatment.
