Ventolin
"I was admitted to hospital for an asthma attack. Had never taken any kind of breathing medication before, even though I'd had trouble with breathing (shortness of breath, tight chest, can't take deep breaths) for a while. I was given Ventolin. I didn't respond to the first few puffs through the inhaler and chamber spacer, so they gave me burst therapy, which involved taking 4-5 puffs every 20 minutes for 2 hours. After the first 40 minutes, I was shaking like crazy, couldn't sit still. This shaking persisted until I went to sleep that night. The ventolin inhaler they gave me DOESN'T help - only a very large dose of ventolin seems to ease the symptoms. Overall, good in high doses for severe asthma but comes with side effects."
