PDE5 inhibitor
Who should not take Tadalafil
A contraindication is a condition under which Tadalafil (Tadalafil) should not be taken because the risk outweighs the benefit. Tadalafil has both absolute contraindications (do not use) and relative cautions (use only after careful review). This page summarises both at the 20mg, 2.5mg, 5mg, 10mg dosing range.
Absolute contraindications
According to the prescribing information for Tadalafil, 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 Tadalafil 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. Tadalafil selectively inhibits PDE5, the enzyme responsible for breaking down cyclic guanosine monophosphate in the corpus cavernosum and other vascular smooth muscle.
