Does Cimzia cause hair loss?

Official answer


Cimzia (certolizumab) may cause a rare type of hair loss known as alopecia totalis, a complete loss of hair on the scalp. The cause for the hair loss may be due to an immune-system reaction while using Cimzia.

Total hair loss is an uncommon (0.1% to 1%) side effect of tumor necrosis factor (TNF) blockers such as Cimzia.

  • Two case reports in patients using infliximab (Remicade), another TNF blocker, described hair loss as an 'anti-TNF therapy-related alopecia', which combines features of both alopecia areata and psoriatic alopecia.
  • Alopecia areata leads to hair loss with circular patches and can occur when the immune system attacks the hair follicles (an autoimmune disorder). Alopecia totalis affects a small percentage of patients with alopecia areata.

A study conducted in France looked at the occurrence of alopecia in patients who had used any tumor necrosis factor (TNF-α) blocker. Researchers reviewed all spontaneous reports of TNF-α blocker-related alopecia recorded in their safety database between January 2000 and April 2012.

  • In the database, 1068 reports of alopecia were identified out of 282,590 reports of adverse drug reactions. Of the 1068 cases, 52 (4.9%) occurred during exposure to TNF-α blockers (18 cases occurred with infliximab, 17 with adalimumab, 15 with etanercept and 2 with certolizumab).
  • Exposure to TNF-α blockers was more frequent in those who reported alopecia as a side effect, compared to the other side effects pooled together.
  • The researchers concluded that there was a strong link between the class of TNF-α blockers and the occurrence of alopecia.

The most common type of skin (dermatologic) reaction with Cimzia is a skin rash that occurs in about 10% of patients (1 out of 10 patients). The rash may occur due to an allergic reaction to the medicine.
