Why do I still get flares even when I take my medication regularly?
A flare while you are taking your medication faithfully is frustrating, but it does not mean you have failed or that the drug is useless. IBD is a relapsing condition, and no treatment removes the risk of flares completely. Triggers like a gut infection, certain painkillers (NSAIDs such as ibuprofen), ongoing stress, or a treatment that is no longer strong enough for you can all set one off. The right move is not to stop your medication but to contact your IBD team, who can look for a trigger and review your treatment.

Taking everything exactly as prescribed and still flaring feels deeply unfair. It helps to know that this is common and usually has an explanation.
IBD can flare even on good treatment
IBD is a long-term relapsing-remitting condition: it has quieter spells and active spells. Cleveland Clinic describes symptoms that "may come on suddenly (flares)," with all treatment aimed at bringing IBD into remission and keeping it there (Cleveland Clinic). Even well-chosen medication lowers the risk of a flare rather than removing it entirely.
Common triggers
Crohn's & Colitis UK notes that "we don't yet know what causes flare-ups," but lists possible triggers (Crohn's & Colitis UK):
- Gut infections.
- NSAID painkillers such as ibuprofen.
- Ongoing stress.
- Disruptions or changes in medicines.
So a flare can have an outside trigger that has nothing to do with how faithfully you take your tablets.
Sometimes the treatment itself needs adjusting
A drug that controlled things well can become less effective over time, or the dose may no longer match what your body needs. That is a clinical decision to make with your team, not something to fix by stopping or doubling up on your own.
What to do
- Keep taking your medication as prescribed unless your team tells you otherwise.
- Contact your IBD team. A flare while on treatment is worth a review.
- A short symptom and trigger diary can help you and your team spot a pattern.
