Who should not take Minoxidil
A contraindication is a condition under which Minoxidil (Minoxidil) should not be taken because the risk outweighs the benefit. Minoxidil has both absolute contraindications (do not use) and relative cautions (use only after careful review). This page summarises both at the 2%, 5% dosing range.
Absolute contraindications
According to the prescribing information for Minoxidil, absolute contraindications typically include severe allergic reactions to the active ingredient or excipients, severe hepatic or renal impairment, certain cardiovascular conditions, and concurrent use of specific interacting medications. The exact list depends on the molecule and is detailed in the official label.
Relative cautions
Relative cautions are situations where Minoxidil can be used but with extra monitoring, dose reduction or alternative considered. These often include mild-to-moderate organ impairment, age extremes, multiple comorbidities, and complex medication regimens. Minoxidil is a potassium channel opener that produces arteriolar vasodilation.
