Poison ivy is typically treated with oral or cream medications, but triamcinolone injections can be administered for some patients, according to WebMD. People who have trouble swallowing pills are sometimes considered candidates for these injections, but there are some side-effect risks.
WebMD reports that corticosteroid pills, such as prednisone, and topical creams, gels or ointments are usually the first lines of defense for poison ivy. Those who opt for shots of triamcinolone, a corticosteroid hormone, face the possibility of discolored skin from an improper injection. Long-term use of both oral and injected corticosteroids can cause serious side effects, such as thinning bones, slowed growth and ulcers.
