Kay,
Your choices as I see them are

1 Stop taking the Latuda. Start Abilify.

2 Keep taking the Latuda with the increased Benendryl.

3 Go to the ER.

Abilify has been around a few years longer than Latuda. Abilify has been prescribed off label for sleep. How is your sleep?

Have you been taking Latuda with food as the manufacturer says? Take it with protein if you want absorption.
Here is the Latuda P.I. sheet if you have not already seen it:
