weird reaction

This morning had my salmeterol,this is in capsule form where a capsule gets pierced and you breath the powder in for that dose and need 2 doses.

This morning after using it once,took another breath again to make sure got all the powder out of the capsule and again for the second dose had a second puff to make sure got all the powder out of that capsule.

Also this morning took one of my usual tabs for my OA but did notice the chemists had given me a different make.

Anyway,straight after taking my meds I came over really weird,all my blood felt hot inside me and light headed and shaky.

Will see if it happens again when take all my meds as normal .

Anybody had the same feeling?
