To manage your ongoing symptoms, several medications can help. For persistent vertigo and spinning, vestibular suppressants like meclizine or betahistine may offer relief, though they are typically used temporarily. If your left-sided weakness is accompanied by muscle stiffness or spasticity, muscle relaxants such as baclofen or tizanidine can help improve mobility. Additionally, ongoing stroke prevention is crucial, usually involving antiplatelets like aspirin or clopidogrel and statins. Since you are three years post-stroke, these medications are most effective when combined with targeted vestibular rehabilitation and physical therapy. Please consult your neurologist to safely tailor these pharmaceutical options to your recovery plan.
