Metronidazole Balance Disorder Causes and Reviews


Have you ever felt dizzy, lightheaded, or as if the room is spinning around you? If the feeling happens often, it could be a sign of a balance problem. Balance problems can make you feel unsteady. You may also have blurred vision, confusion, and disorientation. They are one cause of falls and fall-related injuries, such as a hip fracture.

Some balance problems are due to problems in the inner ear. Others may involve another part of the body, such as the brain or the heart. Aging, infections, head injury, certain medicines, or problems with blood circulation may also cause balance problems.

It is important to see your doctor about balance problems. They can be a sign of other health problems, such as an ear infection or a stroke. Your doctor may send you to a specialist for a diagnosis. You may need a hearing test, blood tests, or imaging studies of your head and brain. Other possible tests look at your eye movements, and how your body responds to movement.

In some cases, treating the illness that is causing the disorder will help with the balance problem. Exercises, a change in diet, and some medicines also can help.

I am deeply indebted to Danny Smith with his comments about Metronidazole. I was also prescribed Metronidazole for a tooth complaint and after experiencing dizziness and being very unwell with nausea, happened to find his remarks on the net. After taking each tablet my symptoms increased and finally searched the net for some information. I immediately stopped my medication and alerted my Dr who has prescribed anti nausea pills and amoxycillin which have settled my symptoms and the infection has reduced in anticipation of root canals to be performed in a couple of days.
