Should a Patient Stop Taking Rinvoq While Feeling Sick?

Do not automatically stop Rinvoq when feeling sick with mild symptoms—this decision must be made on a case-by-case basis in consultation with your healthcare provider, considering the type and severity of illness. 1

Immediate Action Required for Infection Symptoms

If you develop any signs of infection while on Rinvoq, contact your healthcare provider right away before making any medication changes. 2 The FDA label specifically warns that Rinvoq can make you more likely to get infections or worsen existing ones. 2

Signs of Infection Requiring Immediate Medical Contact:

  • Fever, sweating, or chills 2
  • Shortness of breath 2
  • Warm, red, or painful skin or sores on your body 2
  • Muscle aches or feeling tired 2
  • Blood in phlegm 2
  • Diarrhea or stomach pain 2
  • Cough 2
  • Weight loss 2
  • Burning when urinating or urinating more frequently 2

Decision Framework Based on Illness Severity

For Mild Symptoms (e.g., minor cold, mild viral illness):

Treatment changes should be discussed on a case-by-case basis rather than automatically stopping the medication. 1 The 2020 EULAR guidelines (developed during COVID-19 but applicable to general illness management) emphasize that:

  • There is no automatic requirement to stop JAK inhibitors like Rinvoq for mild symptoms 1
  • Patient fears and beliefs may be decisive in the decision 1
  • If you feel safer pausing the medication temporarily and your rheumatologist believes there is no increased risk of disease flare, pausing may be a defendable decision 1

Important caveat: JAK inhibitors can mask certain symptoms such as fever, which may make it harder to assess illness severity. 1

For Worsening or Severe Symptoms:

If initially mild symptoms worsen, immediately seek healthcare advice from an expert in treating the specific infection (pulmonologist, internist, or infectious disease specialist). 1 Your healthcare provider may stop Rinvoq treatment until the infection is controlled. 2

Critical Safety Considerations

When Rinvoq Should Definitely Be Stopped:

Your healthcare provider will stop Rinvoq if you develop: 2

  • A serious infection requiring hospitalization
  • Significant laboratory abnormalities (very low neutrophil/lymphocyte counts, very low red blood cell counts, or very high liver enzymes) 1

Monitoring Requirements While on Rinvoq:

The 2024 ACR/CHEST guidelines recommend: 1

  • CBC with differential and comprehensive metabolic panel at baseline, 4-8 weeks after starting, and every 3 months thereafter 1
  • Hepatitis B, hepatitis C, and latent tuberculosis screening before initiation 1
  • Lipid monitoring at baseline, 4-8 weeks after starting, then annually 1

Special Populations at Higher Risk

Patients at increased risk for serious infections who require more cautious management include: 2

  • Those 50 years and older with cardiovascular risk factors
  • Current or past smokers
  • Those with history of serious or opportunistic infections
  • Those living in areas where tuberculosis or fungal infections are common

Practical Management Algorithm

  1. Assess symptom severity: Mild (minor cold symptoms) vs. moderate-severe (high fever, significant respiratory symptoms, severe pain)
  2. Contact your prescribing physician immediately to report symptoms 2
  3. Do not stop Rinvoq on your own without medical guidance 1
  4. Your physician will determine whether to:
    • Continue Rinvoq with close monitoring
    • Temporarily hold Rinvoq until infection resolves
    • Stop Rinvoq if serious infection develops 2
  5. Seek emergency care if you develop severe symptoms (difficulty breathing, chest pain, confusion, inability to stay awake) 1

Key Clinical Pearls

  • Unlike glucocorticoids (which should never be stopped abruptly), Rinvoq can be safely paused temporarily if medically indicated 1
  • The decision to continue or stop should balance infection risk against the risk of disease flare 1
  • Herpes zoster (shingles) occurs more frequently with Rinvoq, particularly at higher doses 1, 3
  • Most infections in clinical trials were comparable to other biologics, but vigilance is essential 3
