I have been given promethazine for anxiety and have been told I can take 100 mg. I am also on mirtazapine, propranolol and diazepam
"Promethazine is used to treat several conditions, including allergies, motion sickness, nausea and vomiting, anxiety before surgery, and pain after surgery. It's also used as a sleep aid, including before and after surgery. This drug may be used as part of a combination therapy."
I'm not sure that it's FDA approved for anxiety but it is used (probably off-label) for it's sedative effects.
There are a few interactions that you should be aware of like dizziness, drowsiness, headache, etc.:
100mg would be a fairly high dosage but if it was prescribed that way by your doctor that's what you should take. If not, then consult with her/him about taking that dose.
