minor Known Drug Interaction
Upon initiation or discontinuation of IDACIO in patients being treated with CYP450 substrates with a narrow therapeutic index, monitoring of the effect (e.g., warfarin) or drug concentration (e.g., cyclosporine or theophylline) is recommended and the individual dose of the drug product may be adjusted as needed.

Idacio is a medicine that blocks a protein called TNF. It is used to treat several diseases, including arthritis and Crohn's disease.
Theophylline is a medicine that helps you breathe easier. It treats the symptoms of asthma and other lung problems.
Idacio can help adults with rheumatoid arthritis by reducing joint pain and damage. It can also help children (2 years and older) with juvenile idiopathic arthritis. Idacio treats psoriatic arthritis, ankylosing spondylitis, Crohn’s disease, ulcerative colitis, plaque psoriasis, hidradenitis suppurativa and uveitis.
Theophylline treats the symptoms of long-term asthma and other lung diseases. These include emphysema and chronic bronchitis, which make it hard to breathe. This medicine helps to open up your airways so you can breathe easier.
Idacio works by blocking a protein in your body called tumor necrosis factor (TNF). TNF can cause inflammation and damage in certain diseases. By blocking TNF, Idacio can reduce these symptoms.
Theophylline is a bronchodilator. It works by relaxing the muscles in your airways. This allows more air to flow in and out of your lungs.

How to Read This adalimumab vs theophylline Comparison
adalimumab is classified in the TNF-Alpha Inhibitor (Biologic) drug class, while theophylline sits within the Methylxanthine Bronchodilator class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, adalimumab has 219,036 submissions while theophylline has 7,940. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to this medicine can affect the way your body processes theophylline, which might lead to levels that are too high or too low.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for adalimumab or theophylline.
