find no drug with the name "restyl." Do you perhaps mean "RESTORIL," which is a sedative-hypnotic in the benzodiazepine, (antianxiety
) class of meds?
There is also the possibility you meant "RESYL." a trade name for guaifenesin
, which is an expectorant.
If you've been taking RESYL for a cough for the past 6 MONTHS, you need to see your doctor inmediately. The med probably won't hurt you, but a cough lasting 6 months needs looking into.
