The right option is Intolerance
Drug Intolerance is a situation
in which drugs cause adverse effects such as drowsiness or stomach upset and
the body is unable to tolerate or bear these effects. An individual with drug
intolerance may be able to continue with the drugs if the dose is reduced
because drug intolerance sometimes disappears as drug therapy continues.
