Vardenafil FAQs
-
Vardenafil is a prescription medication used to treat erectile dysfunction, which is characterized by the inability to achieve or maintain an erection suitable for sexual activity. This medication falls into the category of phosphodiesterase type 5 (PDE5) inhibitors. Vardenafil functions by enhancing blood flow to the penis, which occurs during sexual stimulation. This augmented blood flow facilitates the process of achieving an erection when sexual arousal occurs. Although it can effectively assist in obtaining an erection, it is important to note that vardenafil is not a cure for erectile dysfunction and it does not enhance sexual desire. Moreover, it is crucial to understand that vardenafil does not prevent pregnancy or the transmission of sexually transmitted infections, such as HIV, which remains a significant health concern.
-
As a PDE5 inhibitor, vardenafil significantly improves blood flow to male genitalia when a man is sexually stimulated. The enhanced blood flow induced by vardenafil serves to help men achieve and maintain an erection during sexual activity, addressing the challenges associated with erectile dysfunction.
-
Typically, vardenafil requires approximately 30 to 60 minutes to reach its full therapeutic effect. For optimal results, it is advisable to take vardenafil around 60 minutes before the anticipated sexual activity to ensure the medication has enough time to become effective.
-
The dosage of vardenafil should be limited to once per 24-hour period. Generally, the effects of the medication can last for up to four hours, allowing for an extended window for sexual engagement.
-
In general, patients should avoid taking the medication more frequently than once every 24 hours. Adhering to this guideline is critical to ensure safe usage and to minimize the risk of potential side effects associated with overuse.
-
Vardenafil is available in the form of standard tablets, as well as a rapidly disintegrating variant that dissolves in the mouth without the need for water. It is typically taken as needed, either with food or on an empty stomach, approximately 60 minutes prior to engaging in sexual activity. It is important to follow the prescribed dosage closely; if you have certain health issues or are using particular medications, your healthcare provider may recommend a different dosing schedule. Always adhere to the instructions provided on your prescription label, and do not hesitate to ask your doctor or pharmacist to clarify any uncertainties regarding your dosage or administration of the medication. Taking vardenafil as directed is essential for achieving the desired therapeutic outcome. Furthermore, if using the rapidly disintegrating tablet form, be sure to inspect the blister pack before your initial dose. If any blisters appear damaged or if there are no tablets present, do not use that pack. Carefully follow the provided instructions to remove the tablet from the blister. Do not apply pressure to push the tablet through the foil. Once removed, place the tablet directly on your tongue and close your mouth to facilitate rapid dissolution. Avoid consuming the rapidly disintegrating tablet with liquids.
Your healthcare provider will likely initiate your treatment with a standard dosage of vardenafil tablets and may adjust the dosage as necessary based on your individual response to the medication. If you are prescribed the rapidly disintegrating tablets, be aware that these are only available in one strength, and your doctor will not be able to modify your dose using that form. If your treatment requires adjustment, your healthcare provider may decide to switch you to the standard tablets. It is essential to communicate with your doctor if you feel that vardenafil is not effective for you, or if you encounter any adverse effects during your treatment. It is important to avoid mixing or substituting the rapidly disintegrating tablets for the regular vardenafil tablets without professional guidance. Always ensure you are administering the exact formulation that has been prescribed for you, and consult your pharmacist if you have questions about your specific vardenafil product.
-
Vardenafil is generally available in three dosage strengths: 5 mg, 10 mg, and 20 mg, intended for administration once daily, as required for treatment purposes.
-
The cost for a prescription of vardenafil can be as low as $3 per tablet without insurance coverage, particularly if utilizing services such as RedBox Rx to manage your prescription needs.
-
It is noteworthy that vardenafil is not available for purchase over the counter and requires a prescription from a licensed healthcare provider. However, if prescribed, it can be conveniently obtained online through RedBox Rx.
-
Before initiating treatment with vardenafil, it is imperative to communicate with your healthcare provider about any allergies you may have to vardenafil, any other medications, or any components within the vardenafil formulation. You should consult your pharmacist for a comprehensive list of the ingredients contained in the tablets.
It is critical to refrain from using vardenafil if you are currently using or have recently utilized riociguat (Adempas) or any nitrates, including isosorbide dinitrate (dilatrate-SR, Isordil, in BiDil), isosorbide mononitrate (Monoket), or nitroglycerin (Minitran, Nitro-Dur, NitroMist, Nitrostat, others). Nitrates can be administered in various forms, such as tablets, sublingual tablets, sprays, patches, pastes, and ointments. If you are uncertain whether any of your other medications contain nitrates, please consult your healthcare provider.
Additionally, avoid the use of illicit drugs that contain nitrates, such as amyl nitrate or butyl nitrate (known as poppers), while on vardenafil.
Inform your doctor and pharmacist about all medications, vitamins, and dietary supplements you are currently taking or plan to take. It is particularly important to disclose any use of alpha blockers such as alfuzosin (Uroxatral), doxazosin (Cardura), prazosin (Minipress), tamsulosin (Flomax, in Jalyn) or terazosin; amiodarone (Cordarone, Pacerone); antifungal medications like fluconazole (Diflucan), itraconazole (Onmel, Sporanox), or ketoconazole (Nizoral); clarithromycin (Biaxin, in Prevpac); disopyramide (Norpace); erythromycin (E.E.S., E-Mycin, Erythrocin); haloperidol (Haldol); HIV protease inhibitors including atazanavir (Reyataz, in Evotaz), indinavir (Crixivan), ritonavir (Norvir, in Kaletra), or saquinavir (Invirase); medications utilized for hypertension or arrhythmias; other treatments for erectile dysfunction; methadone (Dolophine, Methadose); moxifloxacin (Avelox); pimozide (Orap); procainamide; quinidine (in Nuedexta); sotalol (Betapace, Sorine, Sotylize); thioridazine; or verapamil (Calan, COVERA-HA, Verelan, among others). Your healthcare provider may need to adjust the dosages of your medications or closely monitor you for potential side effects. Numerous other medications may interact with vardenafil, thus it is crucial to inform your doctor about all treatments you are receiving, including those not listed here.
Additionally, disclose any herbal supplements you may be taking, particularly St. John’s wort.
It is important to share whether you smoke, and to inform your doctor if you have experienced an erection lasting longer than four hours. Also, inform your doctor regarding any past or current conditions that affect the shape of your penis, such as angulation, cavernosal fibrosis, or Peyronie’s disease; diabetes; elevated cholesterol levels; abnormal blood pressure; irregular heartbeat; past heart attack; angina (chest pain); stroke; gastrointestinal ulcers; bleeding disorders; blood cell disorders like sickle cell anemia (a condition affecting red blood cells), multiple myeloma (a blood cancer), or leukemia (a cancer of white blood cells); seizures; or any issues related to liver, kidney, or heart health. Likewise, inform your doctor if you or any family members have a history of long QT syndrome (a heart condition) or retinitis pigmentosa (an eye disorder), or if you have ever experienced severe vision impairment, particularly if it was thought to have resulted from compromised blood flow to the optic nerves. Additionally, if a healthcare professional has ever advised you to refrain from sexual activity for medical reasons, be sure to convey this to your physician.
Vardenafil is intended solely for male use. Women, especially those who are pregnant, plan to become pregnant, or are breastfeeding, should refrain from using vardenafil. In the event that a pregnant woman ingests vardenafil, she should contact her healthcare provider immediately.
Before undergoing any surgical procedures, including dental work, inform your surgeon or dentist that you are taking vardenafil.
Be aware that engaging in sexual activity may impose additional stress on your heart, especially if you have pre-existing heart conditions. If you encounter chest pain during sexual activity, seek immediate medical attention and avoid further sexual activity until your physician provides further guidance.
Inform all your healthcare providers that you are taking vardenafil. Should you require emergency medical care for a cardiovascular issue, the healthcare staff attending to you will need to know the timing of your last vardenafil dose.
If you have phenylketonuria (PKU), a genetic disorder requiring strict dietary management to prevent neurological damage) you should be aware that the rapidly disintegrating tablet version contains aspartame, which is a source of phenylalanine.
If you have fructose intolerance (a genetic disorder where the body lacks an enzyme needed to metabolize fructose), be advised that the rapidly disintegrating tablets use sorbitol as a sweetener. Please consult your doctor if you have issues concerning fructose intolerance.

Moreover, there have been reports of sudden hearing loss in some patients using vardenafil or other related medications. Such hearing loss typically occurs in one ear and may not improve over time. The cause of this hearing change is also unknown. If you experience a sudden decrease in hearing, possibly accompanied by ringing in the ears or vertigo, while under vardenafil treatment, contact your doctor right away and avoid taking more doses of vardenafil or similar medications until your physician provides further instructions.In the event of experiencing a serious adverse reaction, either you or your healthcare provider may submit a report to the Food and Drug Administration’s (FDA) MedWatch Adverse Event Reporting program either online or by phone at 1-800-332-1088.

Store this medication in its original container, ensuring it is tightly closed and kept out of reach of children. Vardenafil tablets should be stored at room temperature, away from excessive heat and moisture; do not keep them in the bathroom. For vardenafil suspension, ensure it is stored at room temperature or in the refrigerator, but do not freeze it. Any suspension that remains unused after 60 days should be disposed of properly.
It is crucial to keep all medications out of children’s sight and reach, as many containers, such as those for weekly pill organizers and various topical treatments, are not child-resistant and can be easily opened by young children. To prevent poisoning incidents involving young children, always secure safety caps tightly and place the medication in a location that is both elevated and not easily visible to them.
Unneeded medications should be disposed of using special methods to ensure that both pets and children cannot ingest them. It is important not to flush this medication down the toilet. The most effective way to discard your medication is to participate in a drug take-back program. Consult your pharmacist or reach out to your local waste management/recycling authority to gain information about the take-back initiatives available in your area. For further guidance, you may explore the FDA's Safe Disposal of Medicines website for additional resources and options regarding safe disposal techniques.

Symptoms indicative of an overdose may include:
Back pain or muscle discomfort.
Experiencing blurred vision.
-
Do not share your medication with anyone else. If you have any inquiries regarding refilling your prescription, consult your pharmacist for guidance.
It is essential to keep a detailed and updated list of all prescription and over-the-counter medications you are currently taking, as well as any supplements like vitamins, minerals, or other dietary products. Bring this list with you to every doctor appointment or hospitalization. Maintaining this information is also vital for emergencies.
