Viaderm KC is also having same drug i.e triamcinolone acetonide is a topical corticosteroid prescribed to treat a irritation, pain, and swelling associated with injuries. Side effects that may occur while using these creams like pain, burning, or irritation at the application site. The most common cause of elevated phosphorus levels in the blood is decreased kidney function. Rarely, it is due to excess intake of phosphorus or vitamin D, which increases absorption of phosphorus from the small intestine. As you are having increased phosphorus level you need to undergo renal function test to see other parameters. Thank you.
