Randomized Controlled Trial
Effect of oral antihistamine on local injection site reactions with self-administered glatiramer acetate.
Patients with multiple sclerosis often use injectable medication such as glatiramer acetate or interferons to treat their disease. Subcutaneous injections may be associated with local injection site reactions (LISRs), which can include itching, pain, swelling, or redness. Although not serious, these side effects are bothersome and can have a negative impact on adherence to the therapeutic regimen, particularly in early phases of treatment. ⋯ Use of cetirizine did not affect the type of LISRs that was reported at any time point. There were no safety concerns with the concurrent administration of cetirizine with glatiramer acetate. Because there were no statistically significant differences on the primary end point between patient groups taking cetirizine and those taking placebo prior to glatiramer acetate injections, cetirizine use as a strategy to reduce LISRs in patients on glatiramer acetate therapy cannot be recommended at this time.
