Brief Answer:
Phenergan is not known to be addictive

Detailed Answer:
Hello,
Phenergan, or promethazine, is a type of antihistamine used mostly for nausea and vomiting. I have not heard of anyone getting addicted to this medication (without codeine), and in my research do not see any credible information that says it would be addictive or could lead to dependence. The only thing it might do is make it harder to sleep if you do take it for long periods of time and then try to stop it. I would say this would take at least a few weeks of daily use to develop, but most likely would take several weeks to months to develop. So depending on what you are taking it for, I would not be particularly concerned about addiction or withdrawal from this medication.

I hope that helps, please let me know if you have any other questions about that, and I would be glad to discuss it with you further.
Thanks.

Brief Answer:
25mg per dose would be the usual maximum

Detailed Answer:
Usually the most I would recommend for this medication would be 25mg per dose, and no more than 50mg in 24 hours. So I would recommend taking just 25mg before bedtime, and if you only take it once a day, that should be safe.

Please let me know if you have any other questions, I'd be glad to help any way I can.
