Solu-Medrol and asthma attack

my bf had an asthma attack and was given a iv injection of solumedrol at the emergency. when we got home he slept for 3 hours then got up in a bad mood. my daughters boyfriend started some arguing with him and my boyfriend was violent. we have lived together for 4 years and NEVER has he even raised his voice. he was irrational and very, very loud. this drug made him very angry and hyper. he said he felt like his adrenalin was through the roof. after work he came home and was calmer but his eyes were bothering him. (all day they bothered him) i will not let him take this injection again. this guy could drink a bottle of tequila and not be loud or violent. he is a very calm man. the hospital said he would have no side effects to really speak of. it took all i had to try to calm him. he also had 5 doses of albuterol inhalation and 3 doses of ipratroprium brom inhaled. could be combo of all, i don't know. but never again solu-medrol
