My difficult child 1 takes Lexapro for his anxiety, and Ativan on an as-needed basis for medical procedures/blood draws (he has a needle phobia).
Before he started the Lexapro, I had to give him 1mg Ativan to get through blood draws, and he was still panicky with them. Now that he's taking 10mg Lexapro, I only have to give him 0.5mg Ativan, and he handles the same procedures with MUCH less emotion -- no tears, no hyperventilating, no breaking out in a cold sweat, no dizziness or nausea after the event like before.
As for side effects, the Ativan makes him a little sedated. When he was at 1mg, it made him pretty loopy for about 6 hours. At 0.5mg, it just seems to take the edge off his needle fear and relaxes him a bit. Sometimes he complains about feeling weird as it's wearing off -- not sure what that's about.
We haven't noticed any negatives with the Lexapro and he's been on it about 6 weeks.
