I get a Risperdal Consta injection every two weeks on my rear end. It usually is very painful. Now, my nurse uses a Lidocaine/Prilocaine cream, 2.5% each, on the injection area fifteen minutes before the injection. Normally she just puts a little on the injection site and doesn’t rub it in very well. And the shot still hurts a bit. For the last two weeks, I have been having her rub the cream in really good into the injection area and leaving it on for fifteen minutes. The rubbing makes all the difference in the world. I feel absolutely nothing when she gives me my injection now. The area is completely numb. I don’t feel either the needle going in or the medication going in at all. This cream could work just as well on the arm, I suppose.
