Steroid packs like prednisone can rapidly relieve hives by suppressing immune activity, but hives often return once the medication is stopped—a phenomenon known as rebound urticaria. This is especially common in people with chronic urticaria or ongoing exposure to unidentified triggers.

Hydroxychloroquine is often prescribed off-label for chronic hives (chronic urticaria) that don't respond to antihistamines. It works by modulating the immune system, stabilizing mast cells, and lowering inflammatory cytokines, which can significantly reduce itching and wheals over several weeks of treatment. Typically dosed at 200–400 mg daily, hydroxychloroquine is generally well tolerated and carries a lower risk of serious infection than stronger immunosuppressants. However, safe use depends on an accurate diagnosis, baseline eye exams, and routine lab monitoring to rule out urticaria mimickers and track side effects.

Hyposmia from long-term sinus blockages happens when thick mucus, chronic inflammation, and structural obstructions block odor molecules from reaching olfactory receptors, sometimes damaging nerve cells. This reduced sense of smell dulls taste, lowers quality of life, and creates safety risks like missing smoke or gas leaks.

Because causes vary widely, identifying the right treatment depends on your specific symptoms. If you're experiencing a reduced sense of smell, don't guess at the cause.
