What does biologic therapy treat?

Biologics are medicines designed to block or modify specific immune signals involved in inflammation. Dermatology specialists may consider them for plaque or pustular psoriasis, nail psoriasis, hidradenitis suppurativa, and pemphigus vulgaris. The exact medicine depends on the diagnosis, affected areas, previous treatment, other health conditions, and screening results. Adalimumab is one example used in dermatology. Biologic therapy is different from broad immune-suppressing options such as methotrexate, although both may be discussed in a treatment plan.

A specialist usually confirms the diagnosis and checks for factors that could affect safety before starting treatment. Tell the team about infections, long-term conditions, allergies, vaccinations, pregnancy plans, and all medicines. Follow the injection or infusion schedule provided and keep follow-up appointments so symptoms and possible side effects can be reviewed. Do not change, pause, or restart a biologic without guidance; missed doses may require a specific plan.

Contact your treatment team promptly for fever, a persistent cough, painful urination, a spreading skin infection, or a wound that is not settling. Seek urgent care for trouble breathing, facial swelling, severe weakness, confusion, or a rapidly worsening blistering or pustular eruption. A clinician may advise delaying a dose during some infections, so ask what to do if you become unwell.

Which diagnosis and immune pathway is this medicine targeting? What screening or monitoring will I need? How should I handle an infection or missed dose? Which symptoms would mean I should call the clinic immediately?
