<s>[INST] My father has late onset behavior disorder. Doctor prescribed him trazelon 25 mg. Donamen and quitipin. Apart from stilnoct 6.25 in emergency. He was not sleeping and crying so I had given him quitipine and stilnoct both as well. Now he has itiching all over his body. He is feeling mosquito biting. Whether this is side effect or alergy to him. My doctors not available now. [/INST] Hello, I am sorry to note that you are having a difficult time with your fathers skin condition. Traralgon is trazodone which is a sedative sure what Don amen is? Quitipin is quetiapine that is an antipsychotic In short, he needs a sedative antihistamine that will help with the itching, such as Atari or HY Chat Doctor. The others will not work as effectively apart from domain that will also be a good choice. Best Wishes. </s>
