When working with Vardenafil, a prescription medication that belongs to the class of phosphodiesterase‑5 (PDE5) inhibitors, used to treat erectile dysfunction. Also known as Levitra, it works by boosting cyclic guanosine monophosphate (cGMP) levels in penile tissue, allowing blood flow to increase during sexual stimulation.
One of the main reasons men seek Erectile Dysfunction, a condition where achieving or maintaining an erection is difficult is because it can affect confidence and relationships. PDE5 inhibitor, a drug class that blocks the enzyme phosphodiesterase‑5, preventing cGMP breakdown like Vardenafil directly addresses this by keeping the blood vessels relaxed. The drug’s rapid onset—usually within 30‑60 minutes—makes it a popular choice for those who want flexibility without planning hours ahead.
Dosage matters. The typical starting dose for most adult men is 10 mg taken about an hour before sexual activity, with a maximum of 20 mg. Some clinicians recommend a lower 5 mg dose for older patients or those on medications that affect liver enzymes. Because Vardenafil is metabolized by CYP3A4, drugs that inhibit this enzyme (such as certain antifungals or antibiotics) can raise blood levels and increase side‑effect risk. Always discuss your full medication list with a pharmacist before starting.
Speaking of side effects, the most common ones are headache, facial flushing, and mild stomach upset. Rarely, men experience visual changes or a prolonged erection lasting more than four hours—a condition called priapism that needs immediate medical attention. Vardenafil should never be combined with nitrates (like nitroglycerin) because the combo can cause a dangerous drop in blood pressure. Heart patients with unstable angina or recent heart attacks should also avoid it unless a doctor specifically approves.
How does Vardenafil stack up against its peers? Compared with sildenafil (Viagra), Vardenafil often offers a slightly quicker onset and may cause fewer visual disturbances. Compared with tadalafil (Cialis), its effect duration is shorter—around 4‑5 hours versus up to 36 hours—making it a better fit for spontaneous activity rather than daily use. In Canada, both brand‑name and generic versions are widely available, giving patients cost‑effective options without compromising quality.
