  • Would I need to change my lifestyle or other routines while I am on this treatment?
  • Is there any other treatment option for me if this therapy doesn’t work?

Biologic treatment[3][4]

Biologics for Psoriasis target the immune system and are used for those with moderate to severe itchy skin and other Psoriasis associated symptoms. There are various types of biologics for Psoriasis, and your Dermatologist will be the best judge to decide which biologic suits you best.

  • Can be given subcutaneously or via infusion depending upon the type of biologic.
  • Reduces pain, itching and scaling.
  • Improves overall quality of life.
  • Newer biologics help achieve almost clear to clear skin.
