If he is going into anaphylactic shock, what medications needs to be given immediately

The first step for treating anaphylactic shock will likely be injecting epinephrine immediately. this can reduce the severity of the allergic reaction. at the hospital, you’ll receive more in epinephrine intravenously, you may also receive glucocorticoid and antihistamines intravenously.
Hope this helps!! :)
