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

Betahistina Bluefish contains betahistine dihydrochloride. This medication is a type of medication called a "histamine analog". It is used to treat:

Ménière's syndrome.

The symptoms of Ménière's syndrome may include vertigo, tinnitus, hearing loss associated with nausea, otology and/or headache.

• Vertigo (feeling of dizziness). This medication works by improving circulation in the inner ear and thus reducing pressure.
• Tinnitus (ringing in the ears).
• Hearing loss or difficulty hearing.

2. What you need to know before taking Betahistina Bluefish

Do not take Betahistina Bluefish:

• If you are allergic to the active substance or to any of the other components of this medication (listed in section 6),
• If you have hypertension due to a certain type of adrenal gland cancer called pheochromocytoma.

Taking Betahistina Bluefish with other medications

Tell your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.

In particular, tell your doctor or pharmacist if you are taking any of the following medications:

• Antihistamines: this is because, in theory, it may decrease the effect of betahistine. Additionally, betahistine may decrease the effect of antihistamines.
• Monoamine oxidase inhibitors (MAOIs) used to treat depression or Parkinson's disease. They may increase the effect of betahistine.

Taking Betahistina with food, drinks, and alcohol

Betahistine can be taken with or without food. However, this medication may cause mild stomach problems (see Section 4). Taking betahistine with food can help reduce stomach problems.
