Alternatives to biologic therapy

A biologic is one type of targeted immune treatment, while alternatives work through different pathways or focus on the skin surface. The right option depends on the diagnosis, body sites involved, severity, previous treatments, other health conditions, pregnancy plans, infection risk, and monitoring needs. For [Psoriasis](/conditions/psoriasis/), options may include topical medicines, light treatment, or a conventional systemic medicine such as [Methotrexate Treatment](/treatments/medical-dermatology/methotrexate-therapy/).

Do not stop or switch a biologic without the prescribing clinician’s plan, because control can change after treatment is interrupted. Bring a list of medicines, infections, vaccinations, liver or kidney problems, and previous treatment effects. Ask what monitoring is needed and how quickly a replacement option is expected to work. Some diagnoses, including [Nail Psoriasis](/conditions/nail-psoriasis/) or [Hidradenitis Suppurativa](/conditions/hidradenitis-suppurativa/), may need a different strategy from skin-limited disease.

Contact your clinician promptly for a rapidly worsening rash, painful pustules, spreading redness, fever, or new joint symptoms. Urgent assessment is needed for severe skin pain, extensive blistering, facial swelling, breathing difficulty, or a widespread pustular eruption. [Pustular Psoriasis](/conditions/pustular-psoriasis/) and [Pyoderma Gangrenosum](/conditions/pyoderma-gangrenosum/) require specialist-led treatment decisions.

Ask why an alternative is being considered, what benefit and monitoring it involves, how it fits your diagnosis, which warning symptoms matter, and whether a treatment such as [Adalimumab](/materials/adalimumab/) is relevant to your situation.
