Allergic reaction: You may have had an allergic reaction to the medication.

Intolerance/allergy: Sleep aids generally work by penetrating into the brain & disrupting the normal message carriers. By doing so, many can settle into sleep.If whatever dose you took was too disruptive, the effect may be to give you weird sensations. This is an intolerance rather than an allergic reaction, as might occur with a food or bee sting, but you could also have an allergic reaction to any med. Avoid it.

OTC sleep aid: Depends on the otc sleep aid you used but don't take it again until you see your doctor. You may have had an allergic reaction to one of the ingredients. But f you have the difficulty breathing occur again and you did not take the same medication, go to the er.
