Levitra is a drug for the treatment of erectile dysfunction. Levitra restores impaired erectile function and ensures a normal response to sexual stimulation.
The physiological mechanism of erection is the relaxation of the smooth muscles of the cavernous bodies and arterioles. Vardenafil blocks specific phosphodiesterase type 5, which enhances the effect of endogenous nitric oxide, which is released during sexual stimulation from the nerve endings of the corpora cavernosa and increases blood flow to the penis.

Indications and dosage
Used to treat erectile dysfunction (inability to achieve/maintain an erection for sexual intercourse).
Levitra is used orally, administration does not depend on food intake. The recommended starting dose is 10 mg. The tablets are taken within 25-60 minutes. before the start of sexual intercourse (can also be used 4-5 hours before sexual activity). Levitra works after adequate sexual stimulation.
Depending on the effectiveness and tolerability of the drug, the dose may be increased to 20 mg or decreased to 5 mg. The maximum recommended dose is 20 mg, no more than 1 time per day.
For men over 65 years of age, it is recommended to consider the rationality of prescribing an initial dose of 5 mg.
For patients with mild hepatic impairment, there is no need to adjust the dose. For patients with moderate liver failure, an initial dose of 5 mg per day is recommended. In the future, the dose can be increased to 10 mg (taking into account the effectiveness and tolerability). In severe liver failure, the pharmacokinetics of vardenafil have not been studied.
There is no need for dose adjustment in patients with renal impairment. In patients on dialysis, the pharmacokinetics of the active substance of the drug has not been studied.
Overdose
Doses up to 80 mg are tolerated without serious side effects. Possible back pain (muscle or neurological toxicity has not been established). If necessary, provide symptomatic and supportive therapy. The use of dialysis does not increase the clearance of vardenafil.

Frequently Asked Questions
Why is vardenafil considered an option for erectile dysfunction treatment?
Vardenafil is another PDE5 inhibitor with its own onset and tolerability profile. Some patients and clinicians prefer it when they are balancing response quality, timing, and side-effect history.
How is Levitra usually taken?
It is commonly discussed as an as-needed medication taken before sexual activity. The exact interval, dose, and suitability should be determined by a physician who knows the patient's medical history.
Can Levitra be used with cardiovascular medications?
That depends entirely on the medication list. The most important warning involves nitrates, but blood-pressure drugs and other agents also require careful review.
What if a patient had side effects with another ED medicine?
That history may influence whether vardenafil is tried, how the dose is chosen, or whether a different plan is more appropriate. Tolerability differences can matter from one patient to another.
Does Levitra guarantee an erection without stimulation?
No. Like other PDE5 inhibitors, it works within the physiologic erectile pathway and still requires sexual stimulation and adequate vascular response.
What should patients know about dose adjustments?
Age, liver function, kidney status, other medications, and prior response all affect dose selection. Self-adjusting the dose without guidance is not recommended.
Which side effects are discussed most often?
Headache, flushing, congestion, dyspepsia, and dizziness are commonly reviewed. Rare but serious events, including priapism and cardiovascular symptoms, require immediate medical attention.
Can Levitra be compared directly with Cialis or Viagra?
Yes, but the comparison should focus on duration, onset, adverse-effect pattern, and the patient's own priorities. One medication is not automatically best for every situation.
Why does interaction screening matter with Levitra?
Because vardenafil metabolism can be altered by other drugs, especially certain antibiotics, antifungals, and medications that affect liver enzymes.
Why is online information not enough by itself?
Educational pages help patients ask better questions, but the final choice still needs a prescription-based medical review. That is how safety, dose, and suitability are confirmed.
