Vectra 8

Introduction
Vectra 8 is used to prevent and treat a disorder of the inner ear known as Ménière’s disease. The symptoms include dizziness (vertigo), ringing in the ears (tinnitus) and loss of hearing, probably caused by fluid in the ear. This medicine helps relieve the symptoms by reducing the amount of fluid. Vectra 8 should be swallowed whole with water and taken at the same time(s) each day to get the most benefit. Your doctor will decide what is the correct dose to relieve your symptoms and how often you need to take it. You may need to take this medicine for several months and you should take it for as long as you prescribed by your doctor, even if you start feeling better. The most common side effects include headache, feeling sick and indigestion (dyspepsia). You may also get stomach pain and bloating. Taking the medicine with food can help reduce stomach problems. Before taking this medicine, you should talk to your doctor if you have a stomach ulcer, asthma or high or low blood pressure. You must also tell him/her what other medicines you are taking, to make sure you are safe. Also speak to your doctor if you are pregnant, trying to become pregnant or breastfeeding.

How Vectra 8 works
Vectra 8 is a histamine analog. It works by improving the blood flow in the inner ear which reduces the pressure of excess fluid there. Excess fluid can send signals to the brain causing nausea, dizziness or spinning sensations (symptoms of Ménière’s disease). Vectra 8 additionally dampens down the nerve signals sent from the inner ear to the brain relieving the symptoms of Ménière’s disease.

If you miss a dose of Vectra 8, skip it and continue with your normal schedule. Do not double the dose.
