PDE5 inhibitor
Tadalafil and changes in taste or smell
Changes in taste (dysgeusia) or smell (parosmia, anosmia) are an under-recognised side effect category. Some medications produce a metallic taste, a dulling of flavours, or unusual smell perception. Whether Tadalafil (Tadalafil) at 20mg, 2.5mg, 5mg, 10mg causes these changes depends on Tadalafil; the experience is usually benign but can affect appetite and quality of life.
Why taste and smell change on Tadalafil
Taste and smell perception relies on receptors in the tongue and nose that are sensitive to systemic medications. Tadalafil can affect taste through several mechanisms: alteration of saliva composition, direct receptor interference, secretion in saliva of medication metabolites, or changes in zinc handling. Tadalafil selectively inhibits PDE5, the enzyme responsible for breaking down cyclic guanosine monophosphate in the corpus cavernosum and other vascular smooth muscle.
When changes need attention
Mild metallic taste or dulled flavours in the first weeks of Tadalafil at 20mg, 2.5mg, 5mg, 10mg are common and often resolve as the body adjusts. Persistent severe loss of taste or smell, sudden onset, or interference with eating warrants prescriber review — both because the medication may need adjustment and because other causes (zinc deficiency, sinus disease) should be excluded.
Frequently asked questions
Can Tadalafil change my taste or smell? ▾

Will my taste come back when I stop Tadalafil? ▾
