Onset Executive summary and Understanding How It Works
Vardenafil belongs to the phosphodiesterase type 5 inhibitor class. It enhances nitric oxide signaling in penile tissue, promoting vasodilation and increased blood flow when sexual stimulation occurs. An erection requires sexual arousal in addition to the drug effect.
- Typical onset: about 30 to 60 minutes, though some users notice effects sooner than with sildenafil.
- Usual duration: several hours; individual response depends on dose, metabolism, and whether the tablet was taken with a heavy meal.
- Visual negative effects such as altered color perception are reported less frequently with vardenafil than with some other PDE5 inhibitors, but they can still happen.
A simple guide to taking Levitra
- Take by mouth with water. It may be taken with or without food, but a large fatty meal can slow absorption.
- Most patients take one tablet approximately one hour before planned sexual activity. Follow the dose and schedule your clinician prescribes.
- Do not take more tablets than prescribed in a 24-hour period and please keep them separate and not combined. doses to make up for a missed use.
- Missed the dose action plan: Levitra is generally used on demand, so there is no routine dosing schedule to replace a missed planned dose. Do not pair twice.
- If you suspect an overdose incident, seek emergency care immediately or call the U.S. poison control center at 1-800-222-1222.
This medication is prescribed for you only. Do not share it with others.
Think twice before you seize it for yourself: Tell Your Clinician If You Have
- Any heart disease, prior heart attack, angina, heart failure, or irregular heart rhythms
- A history of stroke
- Liver disease or reduced renal performance
- A prior episode of prolonged erection or conditions that increase priapism risk
- Known eye problems including a history of nonarteritic anterior ischemic optic neuropathy or sudden loss of vision
- Bleeding disorders, sickle cell disease, or other hematologic conditions
- Peptic ulcer disease, chronic reflux, or other significant gastrointestinal disorders
- The diagnosis of diabetes, high cholesterol, or other chronic metabolic conditions
- Any history of allergic reactions to vardenafil or tablet excipients
- Current or recent cancer treatments or immunosuppressive conditions
Medications and Food Interactions
NEVER combine vardenafil with nitrates or nitric oxide donors. The combination can cause a dangerous drop in blood pressure.
- Nitrate medications and inhaled amyl nitrite (poppers), including nitroglycerin, isosorbide dinitrate and isosorbide mononitrate
Other agents can change blood levels of vardenafil or increase the chance of harmful impacts. Disclose all prescription, over-the-counter medicines, supplements, and herbal products to your clinician. Examples include:
- Strong CYP3A4 inhibitors: ketoconazole, itraconazole, voriconazole, clarithromycin, erythromycin, and some HIV protease inhibitors
- Drugs that affect heart rhythm: amiodarone, sotalol, flecainide, dofetilide, and related agents
- Alpha blockers used for urinary symptoms or blood pressure: tamsulosin, doxazosin, terazosin, prazosin, alfuzosin
- Certain anticonvulsants and enzyme inducers: carbamazepine, phenytoin, phenobarbital, rifampin
- Some antidepressants and other psychotropic medicines
- Grapefruit juice can raise vardenafil concentrations and should generally be avoided around dosing
Also mention alcohol, tobacco, and recreational drug use to your prescriber, since these can change how the medicine works and influence safety.
Safety Cautions and Data surveillance
- If you experience sudden loss of vision in one or both eyes, stop the medicine and seek urgent medical attention.

- If chest pain, severe dizziness, nausea, or pain radiating to the arm or jaw occurs during sexual activity, stop and get medical help immediately.
- Do not alter the dose without consulting the prescriber. If effects are inadequate or indirect effects are problematic, contact your clinician for reassessment.
- Vardenafil does not protect against HIV or sexually transmitted infections; use barrier methods as appropriate.

Serious - seek prompt medical care

- Severe lightheadedness or fainting
Typical and mild
- Cephalalgia
- System flushing or a warm sensation
- Nose congestion with discharge

- Aches in the muscles or back pain
This list fails to cover all items. Report persistent, worsening, or bothersome effects to your healthcare professional.
Similar medications and other options
Several other phosphodiesterase type 5 inhibitors are commonly used for erectile dysfunction. Choice among them depends on onset, duration, side effect profile, other medical conditions, and cost.
- Sildenafil (Viagra and generics): generally takes effect in 30 to 60 minutes, lasts up to about 4 hours. Visual disturbances are reported more often than with vardenafil.
- Tadalafil (Cialis and generics): onset around 30 minutes; long duration that can extend up to 36 hours. Also available as a low-dose daily option (2.5 to 5 mg) for men who prefer spontaneous activity.
- Avanafil (Stendra): may act faster for some users (as early as 15 to 30 minutes) and lasts for several hours; often remains brand-only at many pharmacies, which increases cost.
If one agent is ineffective or treatment side effects limit use, switching to a different PDE5 inhibitor or adjusting dose under medical supervision can be effective. For typical costs, see Average Prices in the United States.
