Hello and hope you are doing well.
Looks like the medication mentioned is not FDA approved. FDA (Food and Drug Administration) the controlling authority for all medications. If you see all the OTC's and some herbal medications will not have their approval. This is important because, it means that no scientific studies have been conducted for these medications hence interaction with other medications or their side effects would not have been studied, so it is difficult to comment on their side effects. There are a lot of safe medications approved for weight loss, please discuss with your doctor regarding this.
Hope this helped and do keep us posted.
Look up hcg diet and rash. If it has happened to others there should be a lot info about it.
