As far as I know it indeed is, I am told it is sold near the pharmacy in Walmart though I have never had to purchase it myself.
Hello I thank you for live in your question to be answered oh, so the best of my ability I'm not for sure but Walmart do have a pharmacy inside. So it would probably be best to pull them up on the website and give them a call and they can answer your question. Hope this helps good luck.
