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

Betahistine belongs to a group of medicines called antivertigo agents.

Betahistine is used to treat Ménière's syndrome, a disorder characterized by the following symptoms: vertigo (with nausea and vomiting), hearing loss, and sensation of ringing in the ear (tinnitus).

The active substance in this medicine is an analogue of histamine that acts by improving circulation in the inner ear and thereby reduces pressure. The inner ear is one of the organs responsible for the sense of balance.

2. What you need to know before taking Betahistina Stada

Do not take Betahistina Stada

• if you are allergic to the active substance or to any of the other ingredients of this medicine (listed in section 6).
• if your doctor has told you that you have a certain adrenal gland cancer called phaeochromocytoma.

• if you have low blood pressure

Other medicines and Betahistina Stada

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Concomitant administration of betahistina with antiallergic medicines such as antihistamines (especially H1 antagonists) may reduce the effectiveness of both medicines.

It is unknown whether this medicine passes into breast milk; therefore, if you are taking betahistina, you should not breastfeed your child.

Driving and use of machines

Betahistina is indicated for Ménière's syndrome. This condition may negatively affect the ability to drive and use machines. In clinical trials specifically designed to investigate the ability to drive or use machines, betahistina had no effects or effects were negligible.
