How long does sudafed stay in your system?

Answer 1

Sudafed, which contains the active ingredient pseudoephedrine, typically stays in your system for about 24 hours. Its effects can last for 4 to 6 hours after ingestion, but the drug itself may be detectable in urine for up to 1-3 days, depending on factors like metabolism and hydration. Individual responses can vary, so it's important to consider personal health factors as well.
