<s>[INST] HELLO, i have been taking TOLREVA 500 mg , twice a day, and it has been 2 year and 4 months now, i have been visiting my Neurologist on timely basis during this period, i didn t encounter with an seizure episode during this period of treatment, but i do sometimes feel quiet heavy pressure near my left eye , frequent Mood swings, and nausea what could be reasons behind this, and how they can be over comed or treated [/INST] Hi, Thank you for posting your query. Torleva (levetiracetam, Torrent pharma) is a good anti-epileptic Chat Doctor.  It has a very good safety profile. However, in some people, it can cause behavioral problems and mood swings. If these are minor, you may continue to use Korea. However, if your mood swings are severe and affecting your daily life, then, you should consider stopping it and replacing Korea with another seizure medication. Please discuss these issues with your neurologist during the next visit. I hope it helps. Best wishes, </s>
