In the United States an albuterol nebulizer requires a prescription. Pharmacists will refuse to provide one even if they see you dying on the floor. These should be made non-prescription. Wall-mart has the best prices, but you much purchase in-store.
You can buy one from the pharmacy or if you cannot afford it, go to the hospital or clinic but you may also be charge for nebulizer use. Decide what's more affordable for you.
