Starting biologic therapy is often a pivotal moment for people living with Crohn’s disease. These laboratory-created antibodies target specific proteins in the immune system, offering many patients relief from chronic inflammation, symptom reduction, and the potential for remission.
However, initiating this treatment requires more than simply picking up a prescription. Because biologics modulate the immune system, they carry specific risks and logistical requirements. Proper preparation—including safety screenings, vaccination updates, and lifestyle planning—is essential to maximize efficacy and minimize complications.
Here is what you need to discuss with your gastroenterologist before beginning treatment.
1. Complete Essential Safety Screenings
Before receiving your first dose, your medical team must screen for latent infections and underlying health conditions. Because biologics suppress certain parts of the immune system, they can allow dormant infections to reactivate and become severe.
Key Infection Screens:
* Tuberculosis (TB): Critical to rule out latent TB.
* Hepatitis B and C: To prevent reactivation or worsening of liver disease.
* HIV and other latent infections: Depending on individual risk factors and history.
Why this matters: “If these screenings identify a possible infection, getting that evaluated and treated is vital so it doesn’t worsen when the immune system is weakened,” explains Michelle Becker, PharmD, a specialist in IBD pharmacy care.
Additional Health Checks:
Your doctor may also evaluate your status regarding:
* Cervical, colon, and skin cancer risks.
* Mental health conditions, particularly depression.
* Bone density (osteoporosis).
* Liver function, heart health, and history of multiple sclerosis.
2. Update Your Vaccination Record
Both Crohn’s disease and biologic therapy increase susceptibility to infections. Ensuring you are up-to-date on vaccinations is a primary defense strategy.
Inactivated Vaccines (Generally Safe):
Your gastroenterologist will likely recommend ensuring you are current on:
* Influenza (flu)
* COVID-19 (including boosters)
* Pneumococcal (pneumonia)
* Shingles (Shingrix)
* Hepatitis A and B (or the combination Twinrix)
* Tdap (tetanus, diphtheria, pertussis)
* HPV
Live Attenuated Vaccines (Require Timing):
Live vaccines contain weakened forms of viruses or bacteria and are generally not recommended while on biologic therapy due to infection risks. If you need these, they should be administered approximately four weeks before starting treatment:
* MMR (measles, mumps, rubella)
* Varicella (chickenpox)
* Oral typhoid
* Yellow fever
3. Choose the Right Biologic for Your Profile
There is no one-size-fits-all biologic. The choice depends on disease severity, location of inflammation, previous treatment responses, and personal lifestyle factors.
Factors to Discuss with Your Doctor:
* Mechanism and Speed: How quickly does the drug work, and how is it administered (injection vs. infusion)?
* Side Effects: What are the potential risks specific to your health history?
* Insurance and Cost: Which options are covered by your plan?
* Family Planning: Is the medication safe during pregnancy or breastfeeding?
“In my conversations with patients, we review how each option works… so the choice truly feels shared rather than one-sided,” says Dr. Alan Moss, chief scientific officer at the Crohn’s & Colitis Foundation.
4. Plan for Regular Monitoring
Biologic therapy is not a “set-it-and-forget-it” treatment. Ongoing monitoring is crucial to ensure the drug is working and to catch any side effects early.
Standard Monitoring Protocol:
* Blood Tests: Regular checks for blood counts, liver function, and inflammation markers.
* Stool Tests: Fecal calprotectin tests to monitor intestinal inflammation.
* Imaging: Endoscopies (upper or lower) to visually confirm that the gut lining is healing.
Monitoring is typically more frequent during the initial “induction phase” (the first three to six months). A follow-up endoscopy within the first year helps confirm that clinical improvement matches actual tissue healing.
5. Define Success and Manage Expectations
Patience is key. A common mistake is discontinuing a medication too early because immediate relief isn’t felt.
Understanding the Timeline:
* Initial Response: Some patients feel better within days; others may wait up to 12 weeks.
* Full Effect: It often takes four to six months to see the complete benefit of the therapy.
What Success Looks Like:
Success is measured by two metrics:
1. Clinical Remission: You feel better, with fewer symptoms and more energy.
2. Endoscopic Remission: Tests show that inflammation has actually subsided.
If the medication isn’t working within the expected timeframe, your doctor may adjust the dose, check drug levels in your blood, or switch to a different therapy. This pivot is a normal part of treatment optimization, not a failure.
6. Integrate Treatment Into Daily Life
Biologics are long-term commitments. How well they fit into your routine impacts adherence and quality of life.
Practical Tips for Adherence:
* Administration: Many biologics are self-injected at home, taking only a minute or two. Others require clinic visits for infusions. Choose a schedule that aligns with your work and family life.
* Reminders: Since dosing is often weekly, every other week, or monthly, it is easy to forget. Use calendar alerts, apps, or pill organizers to track doses, refills, and appointments.
* Lifestyle Impact: When effective, biologics can restore freedom in work, social, and family life by reducing flares and fatigue.
“The goal is for treatment to be as seamless as possible,” says Dr. Anish Sheth, a gastroenterologist at Penn Medicine Princeton Health.
Conclusion
Starting biologic therapy for Crohn’s disease is a collaborative process that requires preparation. By completing necessary screenings, updating vaccinations, and choosing a treatment plan that fits your lifestyle, you lay the groundwork for successful long-term management. Regular monitoring and realistic expectations ensure that you and your care team can adjust the strategy as needed to maintain remission and improve quality of life.
