Levaquin-Levofloxacin,though it is an antibiotic,has some common adverse effects on CNS as it passes the blood brain barrier.Headache, dizziness, and restlessness are among the commonest effects on the CNS. Others include tremor, drowsiness, insomnia, nightmares, and visual and other sensory disturbances ,tinnitus, Mal de Debarquement Syndrome etc.
Generally these reactions subside when the drug is completely metabolized and eliminated from the body. There is nothing much to be worried.Moreover ,your ear symptoms has also been associated with the same situation, this is probable reason which made you feel worse. Ear suspension/ drops with anesthetics and anti histaminics may help you with your ear symptoms of pain, fullness. They also come with a combination of antibiotics. taken with oral antibiotics and local control of symptoms is the main stay of treatment, which allows ear to heal it self.
Earplugs,initiating Valsalva maneuver, Epley maneuver, head and neck relaxation exercises, sends signals to the brain by activating the vestibulo choclear system, Eustachian tube, in relation to gravity, there fore helps you come out of the situation-this is called Vestibular Rehabilitation Physical Therapy, generally suggested to every person with symptoms of Vertigo of any origin.
You may talk to your doctor about this or talk to the local therapist about controlling vertigo and ear related problems until you are off Levaquin. Hope this helps. Keep us updated.
Thanks Vedadhar for your response. It makes sense. I am doing lot of Vestibular Rehabilitation Exercises regularly. I am doing much better now but still I am not sure what caused my situation.
I have some predisposition to anxiety and I believe it was triggered by just one dose of Levaquin. I distinctly remember I had minor discomfort in ear but no tinnitus or dizziness. But some fullness in ear and may be some hearing loss. I started having vertigo and dizziness (off balance feeling) only after that dose of Levaquin. I don't believe dizziness/balance problem has got to do anything with some issue in vestibular organ. I would feel off balance but then I go to play Tennis and i would play just like days I would when I didn't have this issue. So my balance is all fine and it's more of a psychogenic thing. Do you think still dizziness/off balance feeling might be because of some ear issues?
I have been on treatment for anxiety and depression and I am feeling much better overall. Nervous attacks, dizziness, off balance feeling have gone down very significantly and I am able to carry on with normal life. However, I would like to know if I should still see an ENT.
