Sildenafil and tadalafil both help improve blood flow to support erections, but they work over different timeframes. Sildenafil typically starts working within 30 to 60 minutes and lasts around 4 hours, while tadalafil can provide support for up to 36 hours. Combining them may offer a broader window of effectiveness and greater flexibility. However, taking both together can increase the risk of side effects, including low blood pressure, and should only be done under medical supervision.

FlexDuo is taken on demand, before sexual activity, with no daily commitment. Daily Tadalafil is a low dose taken every day, so you’re always ready without needing to plan around a dose. Which fits better really comes down to how often you’re sexually active and whether you’d rather plan ahead or take something only when you need it.

Most patients notice the medication starting to work within 30 minutes, with effects lasting up to 36 hours due to the Tadalafil component. Sexual stimulation is still needed for it to work. It won’t cause an erection on its own.

Side effects may include headache, flushing, indigestion, or nasal sinus congestion. Because both actives affect blood flow, tell your provider about any heart medications you take, especially nitrates, which shouldn’t be combined with either ingredient.

FlexDuo is available as a monthly or bi-monthly shipment. You can pause, skip or cancel at any time.

A separate one-time $35 sexual health assessment is charged at checkout, which includes your initial consult, unlimited messaging with your doctor, and all follow-up care.
