We have used this product for years. It used to be called Rhuligel.  It is absolutely terrific at stopping the itching of mosquito bites and rashes (like poison ivy and such).   Band Aid recently acquired the product and it is now called BandAid Anti-Itch gel.  I've found it in both a squeeze tube and a small sprtiz bottle which I love, (but they don't have that style everywhere). 

Most drugstores carry this and it is definitely a great item to have on hand now that mosquito season is near.  It really soothes the itching amazingly fast.
