To purchase Tremfya, you will need a valid prescription from your doctor.

Guselkumab, the active ingredient in Tremfya, is an antibody that blocks a protein responsible for inflammation and immune responses. Studies have shown that it can significantly improve skin clearance and quality of life.

Monoclonal antibodies are the type of drugs Guselkumab belongs to. Inflammation and swelling are caused by a natural substance in your body (interleukin-23). It plays a pivotal role in triggering the inflammatory processes that cause psoriasis. By inhibiting the action of IL-23, Tremfya effectively stops the events that lead to psoriatic skin disease. In addition to providing relief from psoriasis symptoms rapidly, Tremfya works to prevent the recurrence of flare-ups by suppressing inflammation at its source.

In addition to treating plaque psoriasis, guselkumab can also treat pain and swelling associated with psoriatic arthritis.

Plaque Psoriasis

In plaque psoriasis, skin cells build up rapidly due to an autoimmune disorder affecting the skin. Plaque psoriasis is characterized by raised, red patches covered in silvery-white scales. It is unknown precisely what causes plaque psoriasis, but it is believed to result from genetic predisposition and environmental triggers.
A common symptom of plaque psoriasis is the appearance of red, inflamed patches on the skin’s surface. Individuals who suffer from these patches often experience intense itching, which can be uncomfortable and distressing. Psoriasis plaques are characterized by silvery-white scales covering red patches. As a result of excessive shedding of dead skin cells, these scales create a striking visual presentation. It can result in dry, cracked, and bleeding skin due to plaque psoriasis. As a result of rapid cell turnover and the accumulation of dead skin cells, the skin can feel rough and dehydrated.

Even though plaque psoriasis has no known cure, various treatment options exist to manage its symptoms and relieve those affected. Corticosteroids, vitamin D analogs, and retinoids are commonly prescribed to reduce inflammation and slow skin cell growth. Treatments such as these are often effective in minimizing itching and scaling. Phototherapy involves exposing the skin to controlled amounts of ultraviolet light. As a result, plaque psoriasis symptoms can be alleviated, and the production of skin cells can be slowed down. A systemic medication such as a biologic or oral immunosuppressant may be prescribed in severe cases. Plaque psoriasis is caused by overactive immune responses managed by these medications.
