“At a certain age in many people the problem starts with the vessels of the head, accompanied by headache, dizziness, tinnitus. This happened to me. For a long time did not wait, asked for help to a neurologist. The doctor prescribed meseveral medications, among which was Betaserc. After regular use (I'm on the pill max dosage in 24 mg 2 times a day) dizziness passed, but the tinnitus remained. No side effects I have identified. With the cons of this drug can point out is that price. Unfortunately, to keep buying such expensive medicine I can't afford it.”
