About vardenafil

Vardenafil is commonly prescribed to treat erectile dysfunction. Vardenafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. Vardenafil works by temporarily increasing the blood flow to the penis during periods of sexual stimulation. It is available with a prescription as a generic or as the active ingredient in Levitra.

Now Patient offers vardenafil for the treatment of erectile dysfunction only, following an online consultation with a prescribing clinician.

Key facts of vardenafil

  • Vardenafil usually takes 60 minutes to work
  • Vardenafil does not result in an erection if taken alone. You would need to be sexually excited for it to work
  • Vardenafil has some common side effects which include headaches, facial flushes, feeling sick, and indigestion. Many people display no side effects, or if they do the side effects can be mild
  • It can be dangerous to take vardenafil with certain medications like alpha blockers or nitrates (nitroglycerin, isosorbide mononitrate). The combination can lead to a dangerous fall in your blood pressure. If you’re not sure if you’re taking a nitrate, you can discuss this with the prescribing clinician
  • You should avoid drinking grapefruit juice if you’re taking vardenafil prescribed for pulmonary hypertension because it affects the way the medicine works

Who is vardenafil suitable for?

Vardenafil is suitable for most men aged 18 and over.

Who is vardenafil not suitable for?

Vardenafil may not be suitable for some people. To make sure it’s safe for you, speak to the prescribing clinician before taking vardenafil if you:

  • Have low blood pressure (hypotension) or high blood pressure that is not controlled (hypertension)
  • Have sickle cell anaemia, leukemia, or multiple myeloma
  • Have a deformity of your penis or Peyronie’s disease (curved penis)
  • Have previously had an allergic reaction to vardenafil
  • Are taking nitrates for angina (chest pain)
  • Have a serious liver or kidney problem
  • Have recently had a heart attack, stroke, or other heart problem – your healthcare professional should carefully check whether your heart can take the additional strain of having sex
  • Have reduced blood flow to your eye causing you to lose your vision

How and where to get vardenafil ?

Vardenafil tablets are available from a number of sources. It is available on NHS or private prescription.

Now Patient does not allow customers to buy vardenafil directly. Our service is certified, safe and effective, and we only ever treat conditions. If you book a consultation with a prescribing clinician for the treatment of erectile dysfunction, you can discuss if vardenafil is a suitable treatment option for you.

At the end of the consultation, the clinician will decide if a treatment plan is suitable for you. If it is, the clinician will issue you with a prescription which can then be ordered, paid for and delivered directly to your chosen address by Now Patient.

Dosage and strength for vardenafil when used for erectile dysfunction

Vardenafil is available in tablet form and when used for erectile dysfunction it is available in strengths ranging from 5mg to 20mg tablets. The typical daily dose of vardenafil is a 10mg tablet, taken 60 minutes before sexual activity. The effects of vardenafil may last longer than 24 hours so do not take it more than once a day. This dose can be adjusted up to 20mg or decreased to 5mg depending on the effects. Read the patient information leaflet provided to you with your medication.

What happens if you take too much vardenafil ?

If you take more than prescribed, then it can lead to some unpleasant side effects.

You should talk to your doctor or reach out to one of our prescribing clinicians, if you have taken too much vardenafil and you experience any of the following side effects:

  • Headaches
  • Lightheadedness and dizziness
  • Indigestion
  • Nasal congestion
  • Hearing loss
  • Blurred vision

What are the side effects of vardenafil ?

Side effects of vardenafil are split into common and serious. If you are prescribed vardenafil for the treatment of erectile dysfunction, you’re unlikely to get side effects, since you are only taking it short term.

Common side effects include:

  • Headaches
  • Feeling sick
  • Facial flushing
  • Hot flushes
  • Indigestion
  • Muscles aches
  • Back pain
  • Stuffy nose

Serious side effects include:

  • Sudden decrease or loss of vision
  • Serious allergic reaction
  • Priapism (long-lasting and potentially painful erection)
  • Heart attack, stroke, or irregular heartbeat, which mainly occur in people with heart disease

If you experience any serious side effects, you should contact NHS 111.

If you experience a serious allergic reaction with the signs shown below you should contact emergency services on 999.

  • Your lips, mouth, throat or tongue suddenly become swollen
  • You’re breathing very fast or struggling to breathe (you may become very wheezy or feel like you’re choking or gasping for air)
  • Your throat feels tight or you’re struggling to swallow
  • Your skin, tongue or lips turn blue, grey or pale (if you have black or brown skin, this may be easier to see on the palms of your hands or soles of your feet)
  • You suddenly become very confused, drowsy or dizzy
  • Someone faints and cannot be woken up

Always report adverse effects to the MHRA yellow card reporting system. You can read more about this here https://nowpatient.com/blog/how-and-where-do-i-report-side-effects-of-my-medication

Information about taking vardenafil at the same time as other medications or herbal supplements

You should inform your doctor or prescribing clinician if you are currently taking any medications called nitrates (such as isosorbide mononitrate, amyl nitrate), riociguat, alpha blockers (doxazosin, tamsulosin), certain antifungals (itraconazole, ketoconazole), certain antibiotics (erythromycin, clarithromycin), HIV protease inhibitors (ritonavir, indinavir), medications for high blood pressure, drugs to treat heart arrhythmias (quinidine, amiodarone, sotalol), or other treatments for erectile dysfunction.

There is not enough evidence to suggest there are any drug interactions between herbal supplements and vardenafil. In any event, you should let your prescribing clinician know if you are taking any herbal supplements.

Why might vardenafil not work for erection problems?

Vardenafil may not work for you and common reasons may be:

  • You have not waited long enough after taking it before trying to have sex
  • You have waited too long after taking it to have sex
  • The dose is not high enough
  • You’re not sexually aroused

Can vardenafil taken for erectile dysfunction be taken long term?

Vardenafil is safe to take for a long time. There do not seem to be any lasting harmful effects from taking it for many months and years.

Is there a herbal vardenafil ?

No. Herbal vardenafil does not exist. If you have been marketed such a formulation, it may be fake.

Should I avoid any particular food or drink when taking vardenafil ?

You can eat and drink normally when taking vardenafil to get an erection.

What lifestyle changes can I make to help me with erectile dysfunction?

You modify your lifestyle in a number of ways, and this may have a positive impact on your erectile dysfunction.

  • Maintaining a healthy weight
  • Quitting smoking
  • Cutting down on the amount of alcohol you drink
  • Not taking recreational drugs
