Xeljanz complications and side effects

Tofacitinib works by suppressing the immune system and is associated with a number of adverse side effects that are displayed on the product label.

Common Xeljanz side effects include:

  • Diarrhea
  • Cellulitis
  • Throat irritation, stuffy nose, and cold symptoms
  • Headaches
  • Increased blood pressure
  • Shingles or skin rash

Less common reactions to the drug:

  • Serious bacterial infections
  • Non-melanoma skin cancers
  • Angioedema
  • Increased liver enzymes
  • Systemic fungal infections
  • Perforations of the stomach or intestines
  • Blood clots in the arteries or lungs
  • Pneumonia
  • Malignant Lymphoma
  • Squamous Cell Carcinoma

Due to the life-threatening nature of blood clots, the FDA encourages health care professionals to stop Xeljanz in patients who show symptoms of thrombosis (blood clots). Patients who are experiencing signs of a Xeljanz pulmonary embolism must seek medical attention immediately. Shortness of breath, unusual sweating, and severe chest pain may be early indicators.

Xeljanz FDA warning

In July of 2019, the FDA issued a new warning about an increased risk of pulmonary embolism and death in those taking 10 mg of Xeljanz and Xeljanz XR twice daily. This dosage is commonly prescribed to patients suffering from ulcerative colitis. Symptoms of blood clots include sudden difficulty breathing, leg pain or tenderness, swelling of an arm or leg, or chest pain that becomes worse with breathing. The boxed warning is based on the interim results of a clinical trial that found a higher rate of blood clots in the lungs and death in patients treated with 10 mg of Xeljanz twice daily compared to those taking an alternative drug or lower doses.

Xeljanz complaints against Pfizer

There are many allegations that plaintiffs may level in a Xeljanz lawsuit claim. Pfizer may have to defend complaints that the company:

  • Failed to conduct sufficient pre-market trials to establish the safety of Xeljanz and Xeljanz XR
  • Negligently failed to disclose that higher doses of the drug can induce life-threatening blood clots and other side effects
  • Manufactured, marketed and sold a drug that is unreasonably dangerous for its intended purpose


Given the recent FDA warning about Xeljanz pulmonary embolism risk and deaths, Pfizer may be named in dozens of lawsuits across the nation in the coming months.
