Levitra Dosage Instructions

Before we proceed any further, it is important to understand that the exact Levitra generic dose should be appointed to you by a doctor. You will need to answer your doctor’s questions, get subjected to physical examination, and possibly some laboratory tests before the recommended dose is established to you.

What are the doses of Levitra generic available?

Vardenafil content in Levitra pills, according to the data fixed in the FDA database, is as follows in the versions of the drug approved by the regulatory authorities: Levitra 5mg, Levitra 10mg and Levitra 20mg. In the table below, you will find the efficacy percentage equivalents of the three available vardenafil doses. Vardenafil 40mg is not an approved dosage, since Levitra maximal dose is fixed at vardenafil 20mg.

Levitra dose vs. efficacy

So what is the right Levitra dosage and how long does it last? No matter how big a dose of your vardenafil pill is, the duration of Levitra effects spans between 4 and 8 hours. The exact duration of the drug’s effects is determined by other factors, such as your generial health condition, the presence of enzymes metabolizing vardenafil, the time elapsed since your last meal, the severity of your ED condition, and some others.

Levitra effectiveness, as well as its side effect, on the other hand, are dose-related. What does it entail? It means that your doctor will evaluate the dose at which you get the best health outcomes with minimal adverse reactions. The rule of thumb here is to start with either a minimal dose (especially if you have compromised liver or kidney function) and gradually move up the dose by minimal increments if the initial dose does not yield meaningul results. But more commonly, the median dose of Levita 10mg is prescribed.

Let us not forget that vardenafil, the active substance in Levitra, is effective at smaller doses compared to, say, sildenafil (Viagra) or avanafil (Stendra), the substances that are taken in doses up to 100mg and 200mg respectively. This property makes Levitra the safest oral drug against erectile dysfunction on the market. Even at maximal dose, Levitra is reported to have mild and transient side effects. However, if you are experiencing Levitra side effects that are bothersome or continuous, talk to your prescriber about a dose adjustment.
