Hello.My sister has migraine and OCD.She was taking propranolol(ciplar-40) and serlift(150mg).She had psychosis recently.The psychiatrist gave her risperidone(sizodon plus) and serlift(150mg) but discontinued propranolol(given by the earlier neurophysicist doctor) completely.She has recovered from psychosis but have continued to take the medicines as adviced by the doctor.But just like earlier (when she had no psychosis),whenever she travels She has severe headache.Can she start taking propranolol with risperidone and serlift to combat both the problems.If yes then what should be dosage and what are the possible side effects?Thanks in anticipation of your response.

### output:

Hello user, I understand your concern. Tablet propranolol is used for prophylaxis of migraine attacks, it is not useful for acute attacks. So if your sister is having occasional headaches only (less than 4-5/month) - and if she would be my patient I would have advised taking medicines like 1 tablet headset(sumatriptan+naproxen) SOS basis only - however if attacks are more frequent and troubling than propranolol can be given in the dose she was earlier maintained on (but if psychiatrist stopped it, there could be some rationale behind it so better to discuss with him/her rather than taking medicine on own) propranolol can cause hypotension, can worsen preexisting respiratory difficulties, can worsen depression, and glycemic control among other side effects- but they do not occur in all patients-hope I answered your query, any followup queries are welcome - if satisfied please rate the answer
