Thank you for asking! The medicines you were prescribed are remotely connected with dizziness, one is antipsychotic, other is anticonvulsant and last one is a skeletal muscle relaxant. get your dizziness and vertigo evaluated first , evaluate your vestibular functions, sort out whether it is central or peripheral vertigo and then the management will be complete and useful and the use of mentioned medicines is for short term only. Its causative agents are too many and it needs an expertise of otrhinolaryngologist and neuro otologist to sort out the cause with help of Auditory, vestibular, complementary blood and radiologic tests help in narrowing the differential diagnosis and tailoring treatment. Simple flu and anxiety depression can cause that too. So can the headaches and migraines.many over the counter medicines to herbal remedies also cause that. As you recently quit smoking it itself is the major contributing factor to vestibular imbalances due to withdrawl effects. It needs to be evaluated in detail for sorting out whether it is due to peripheral or central causes. Peripheral causes are BPPV, vestibular neuronitis, Ménière disease, and immune-mediated inner-ear disease. The most common cause of central dizziness is migraine, frequently referred to as vestibular migraine or migraine-associated dizziness. Other central causes include demyelination, acoustic tumors, and brainstem or cerebellar vascular lesions. Most of these dizziness spells self resolve in 6 to 8 weeks. All you need is safety measures and vocational rehabilitation to avoid any dizziness induced falls and trauma. Simple steroid drops, betahistidines, meclizines and some amoxicillin antibiotics, vestibular suppressants, antiviral medication, and antiemetic medications will help. You need to seek the otorhinolaryngologist and otoneurologist for a detailed examination and a complete clinical correlation. I hope it helps.
