Yes. Options for the treatment of erectile dysfunction include other PDE5 inhibitors such as Tadalafil, a drug often sold under the brand name Cialis. It works in the same way, but the drug has a longer half-life – meaning that it can be effective for up to 36 hours. As such, it gives you a little more flexibility on when you can expect an erection and less need to plan sex within a specific 4-5 hour window. Other ED treatments include penile injections and vacuum devices, which are not quite so easy or user friendly.
