Anyone using Tadalafil 5mg every other day instead of daily?

Tadalafil/Cialis

Hey everyone,

I’m currently looking into low-dose Tadalafil and noticed that the standard recommendation is usually either 2.5mg–5mg daily or a larger dose on demand (10mg–20mg).

However, given Tadalafil’s long half-life (around 17.5 hours), taking 5mg every other day theoretically keeps a stable amount of the medication in your system while reducing overall intake and potential side effects (or costs).

If you've tried taking 5mg every other day instead of daily:

  • Effectiveness: Does it still provide consistent, "always ready" benefits, or do you notice a dip on off-days?
  • Side Effects: Did taking it every two days help minimize things like muscle aches, heartburn, or nasal congestion compared to daily use?
  • Why did you switch? Was it based on doctor advice, cost-saving, or just experimenting to find the minimum effective dose?

I’d love to hear your personal experiences, pros/cons, or any insights your urologist shared with you about this dosing regimen.

Thanks!
