Steroids for asthma: ...Are very unlikely to do you any harm, especially at that dose and for short period of time. You need to get help for the heroin habit, which is harmful with or without steroids. Stop killing yourself, and get help. Your asthma needs to be controlled, but your heroin habit is a greater threat to your survival.

Not the prednisone: Prednisone is relatively safe to use for short duration. The danger of Prednisone is too much, too often, too long a time. It doesn't sound like you are in this category. The heroin on the other hand is a one way ticket to destruction of yourself and those around you. Get help. You made a mistake getting addicted. Stop blaming yourself. Get help on your side to slay the addiction monster.
