Switching to or from Erectile Dysfunction (ED)
Switching medications is more nuanced than simply stopping one and starting another. For Erectile Dysfunction (ED) (Erectile Dysfunction (ED)), the right protocol depends on whether the switch is within the same class, across classes, the half-life of the medications involved, and any underlying disease control. This page outlines the practical considerations at 20mg, 100mg, 10mcg, 20mcg, 40mcg.
Switching within the same class
Switching from another Erectile Dysfunction (ED) agent to Erectile Dysfunction (ED), or vice versa, is usually direct: the prescriber establishes the equivalent dose of Alprostadil, Avanafil, Dapoxetine, Sildenafil Citrate, Tadalafil, Vardenafil and the schedule, and the change happens on a defined day. Symptom monitoring during the first weeks confirms the new regimen is delivering equivalent control. The first-line pharmacological options for adult men are oral phosphodiesterase type 5 inhibitors, including sildenafil, tadalafil and vardenafil.
Switching across classes
Switching to Erectile Dysfunction (ED) from a different therapeutic class is more involved. Some switches require a washout period (especially when crossing receptor antagonists/agonists or shared metabolic pathways), others use cross-titration where both medications overlap briefly. The prescriber chooses the protocol based on the medications involved, the indication and individual factors at 20mg, 100mg, 10mcg, 20mcg, 40mcg.

What should I do if the switch isn't working? ▾
