Primatine Mist can help sometimes. It is epinephrine in an inhaler & is sold over-the-counter in most pharmacies & drug stores.
Breathing the aroma of coffee can help too, if you're not allergic to it.
Benadryl (antihistamine) helps my husband when he gets an Asthma attack; be careful, it can make you sleepy. Claritin (Loratadine) is available over-the-counter also - and is a 24-hour non-drowsy antihistamine.
Ask a pharmacist if there are any other over-the-counter Asthma medications you can try.
Some stores like Walmart have walk-in clinics that don't cost as much. Call a pharmacy and ask if they know of any walk-in clinics.
I hope these suggestions help - good luck,
