Living with Crohn’s disease often feels like being caught between a rock and a hard place. On one side, you have the very real danger of leaving an autoimmune disease to run wild in your gut. On the other side, you have the intimidating list of side effects that come with biologic medications. This internal friction is one of the hardest parts of being a patient, but understanding the specific “tactics” of each drug class can help you make a move with confidence.
According to a report by Everyday Health (2026), the goal of modern treatment is no longer just managing symptoms; it is about preventing permanent structural damage to your body.

The Risks of the “Wait and See” Approach
Before diving into drug side effects, it is vital to understand what happens if Crohn’s goes untreated. When inflammation is left unchecked, it doesn’t just stay on the surface of your intestines. It can lead to:
- Strictures: Scar tissue that narrows the bowel, often requiring surgery.
- Fistulas: Abnormal tunnels that connect the intestine to other organs or the skin.
- Systemic Issues: Inflammation that spreads to the joints (arthritis), eyes, and skin.
Anti-TNF Drugs: The Experienced Veterans
Anti-tumor necrosis factor (anti-TNF) drugs, such as Remicade and Humira, were the first biologics on the scene. As Dr. Alan Moss explains, these drugs have over 20 years of clinical experience behind them. They are the “tried and true” option for many.
- The Advantage: They work incredibly well for patients with extra symptoms like arthritis or for those dealing with fistulas. They also have the longest track record for use during pregnancy.
- The Trade-off: Because these drugs suppress the immune system more broadly throughout the entire body, they carry a slightly higher risk of serious infections. This risk increases if you are also taking other immune-suppressing meds like steroids.
IL-23 Inhibitors: The Targeted Newcomers
Newer classes of biologics, such as IL-12/23 and IL-23 inhibitors (including Stelara and Skyrizi), represent a shift toward precision medicine. Instead of a “broad-brush” approach, these target very specific pathways in the immune system.
- The Advantage: According to Dr. Moss, these newer drugs are often described as having a more “gut-focused” effect. Because they are more selective, real-world studies show fewer serious infections compared to older biologics.
- The Long Game: Patients tend to develop fewer antibodies against these drugs, meaning they can often stay on the same medication longer without it losing effectiveness.
Choosing a biologic is a personal tactical decision. To manage this process, implement these habits:
- The Whole Body check: Keep track of symptoms outside your gut. If you have joint pain or skin rashes, tell your doctor; this might make an anti-TNF a better choice for you.
- Infection Monitoring: If you are on an older biologic, be extra vigilant about small infections (like a cold or a cut that won’t heal). Catching them early is key when your immune system is suppressed.
- The Sustainability Check: Ask your specialist about the “antibody risk.” If you want a drug you can likely stay on for a decade or more, the newer IL-23 inhibitors might be the stronger play.
The Bottom Line
In the battle against Crohn’s, there is no such thing as a “risk-free” path. However, the risk of untreated inflammation, which leads to surgery and disability, is almost always higher than the managed risks of biologics. Whether you choose the long-standing reliability of an anti-TNF or the targeted precision of an IL-23 inhibitor, the most important thing is to stop the fire before it burns down the house.
