Depends...: On which side-effect, how much you took, & your personal susceptibility. If you took a standard dose for hives, say 10-25 mg, and had sleepiness as a side-effect, expect resolution in 8-24 hours. For more specific answers discuss your concern with your physician or other health care provider.

Itching, anxiety: Atarax (hydroxyzine, also sold as vistiril) is a sedating antihistamine. In addition to relieving anxiety, it can also help allergic itching, nausea, & motion sickness. It is non-addictive but can cause drowsiness & other (mostly minor) side-effects. See: http://www.Ncbi.Nlm.Nih.Gov/pubmedhealth/pmh0000796/.
