For these top-ranked reactions alone, budesonide has 20,555 submissions while nirmatrelvir/ritonavir has 56,802. 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 moderate interaction flagged in FDA labeling, attributed to the antiviral blocks the natural process your body uses to get rid of budesonide, causing the steroid levels to rise. this can lead to serious side effects like hormone imbalances and adrenal suppression..
