You need to get the message out to your online pharmacies in india because they are shipping promethazine theoclate in place of phenergan, promethazine, hcl. And it's a very toxic drug. I had a serious allergic reaction to it. Please get the message Out to the online pharmacies: do not substitute promethazine, theoclate avocen, avimax etc..for phenergan, promethazine, hcl...they are not interchangeable nor are they fda approved in the usa Thank you Hl (Posted by , United States Date : 3/21/2012 )
