And for Johannaâs dog, itâs vital that you also take your dog to see a vet as you are wanting to know if your dog has kidney problems, though you havenât stated as to why you would think this is what is wrong with your dog. To be safe a quick check up is usually all that is needed to give you peace of mind and your dog the all clear.
Expired Rogaine Foam. Iâve seen expired Rogaine foam on ebay selling for rather cheap. I could understand that overtime, a drug might lose its effectiveness, but I canât imagine that Minoxodil spoils like milk.
Rogaine, the brand name for minoxidil, was the first FDA approved medication for the treatment of hair loss. Rogaine is a topical solution that is applied directly to the scalp. It can now be purchased without a prescription and in generic formulations in concentrations of 5% (for men) and 2% (for women).nce a day topical use of Rogaine (topical minoxidil 2% and 5%) seems to be almost as effective as using it twice a day. The reason is, that although minoxidil has a relatively short half-life of several hours when given orally, when topically applied, it has a half-life of 22 hours in the skin.
