Generic Levitra tablets contain an active ingredient called vardenafil. Each tablet contains either 2.5mg, 5mg, 10mg or 20mg vardenafil. Your doctor – or online doctor – will make a dosage recommendation based on your medical history. For men who are trying Levitra for the first time, the recommended dose is 10mg. The maximum dosage of Levitra is 20mg. You must not exceed this dosage, as this increases the risk that Levitra causes side effects, including serious ones such as priapism (a prolonged and / or painful erection which can damage your penis). If Levitra doesn’t work for you, there are other medications you can try, such as Viagra, Cialis or Spedra. Just like the 20mg pills, 10mg ones can be split into several parts by patients, for whom a lower dose of vardenafil is sufficient. We actually recommend you to go with this Levitra strength, especially if you need 2.5mg of vardenafil per intake – it’s much easier to split a pill into 4 even parts than into 8. Being a PDE5 inhibitor, just like sildenafil (Viagra) and tadalafil (Cialis), vardenafil (Levitra) works by increasing blood flow in the pelvic area. That allows more blood to enter the penis and triggers a healthy strong erection.
