What Causes Low Libido And Swollen Face When Diagnosed With Schezoeffective Bipolar Disorder?

Hi, I am diagnosed for schezoeffective bipolar disorder. I was on Sulphitac 200 to 400 mg for over 6 years. Post the same based on an interim discontinuation for 15 days, I was admitted to hospital on parents consent. I was administered with 3 doses of Invega Sustenna over a period of 1.5 months. Now I am back on Sulphitac 200 mg. However recently ( 8 months after hospitalization) I see that my libido has drastically come down, my neck and face have swollen and become huge, I feel less alert while driving. This is only like last month. Can you please help, especially on the swelling on urgent basis.
