If the above link doesn't work then go to the following link, click on P then click on premarin tablets. http://www.rxmed.com/prescribe.html I found no information regarding the premarin patches. I was asked how I knew there were premarin patches, I heard several years ago there were so I assume they are still available. I will be checking any patch before use . Thank you to all who responded, I have posted this information for the many people that asked me where I got my information about premarin tablets from I do hope that this is helpful. Christina
