Vardenafil(Levitra) : All Things You Need To Know

Introduction

Vardenafil orLevitraas it is commonly known, is a drug used for treating erectile dysfunction (ED). Erectile dysfunction or impotence is a condition wherein a man faces difficulty in achieving and sustaining a healthy erection. ED is caused due to lack of blood flow to the penile structure

Vardenafil is a PDE5 inhibitor. It works by promoting the blood flow to the penis, following the same mechanism as Sildenafil (Viagra) and Tadalafil (Cialis), other PDE5 inhibitors. Even though they are administered for addressing the same medical issue, they have different effects and are administered in varying doses.

Usage

Vardenafil is primarily prescribed for treating ED. It does so through a series of chain reactions in the body. Vardenafil works by inhibiting the growth of the PDE5 enzyme in the body, which, in turn, is responsible for destroying the cyclic guanosine monophosphate (cGMP) enzyme. The cGMP enzyme allows the blood vessels to dilate. After taking Vardenafil, cGMP content in the bloodstream increases, consequently allowing for increased blood flow to the penis.

However, you must be sexually aroused when you are consuming Vardenafil, as being in a state of sexual arousal is a necessary precondition. When aroused, your body releases nitric oxide, an important chemical needed for blood vessels to broaden and permit the entry of greater amounts of blood.

Vardenafil is sold in blister packs, in two forms. The first one is a normal tablet to be taken with water while the other one is a rapidly disintegrating (orodispersible) tablet which starts to disintegrate as soon as kept in the mouth. Always take the understated measures when taking the orodispersible Vardenafil tablet.

  • Wash and completely dry your hands before taking the tablet.
  • Check the blister pack and do not consume the tablet if the packaging appears to be tampered with.
  • Do not use any drink to swallow the tablet.

Dosage

Vardenafil is available in doses of 2.5 mg, 5 mg, 10 mg, and 20 mg. The usual dose prescribed is 10 mg. The small doses of Vardenafil should not be underestimated. A single 10 mg dose of this drug is equal to a 50 mg dose of Viagra. Vardenafil is also longlasting in contrast with Sildenafil. It lasts for about 6 to 8 hours.

Vardenafil should be consumed only once in a 24hour window. It should not be used regularly unless the same is prescribed by your doctor. Usually, Vardenafil is taken on a needonly basis. For the best results, try taking your dose of the medication 30 to 60 minutes before sexual intercourse.

Generally, any kind of adjustment in dosage is not required for Vardenafil. The usual dose of 10 mg should suffice unless otherwise prescribed. For instance, in the case of patients with liver disease, a 5 mg dose should be given, and subsequently increased if needed, considering the tolerability of the patient and efficacy of the drug.

Food and alcohol (mild amounts) do not have a significant impact on the functioning and absorption of Vardenafil. As a result, it can be taken with or without food. It should also be noted that the orodispersible tablets can’t be swapped for the normal ones. If you need to constantly change your Vardenafil doses, you should opt for the normal tablets as the orodispersible ones are available only in one type of dosage amount. Vardenafil is administered only by the oral route.

Risks

Like any other drug, Vardenafil also has its share of risks. you might want to know some of them if you are taking it.

  • Heart IssuesIf you have suffered a cardiac arrest in the past or if you face any cardiac issues like angina or arrhythmia currently, you should consult a doctor before consuming Vardenafil. In fact, the product information leaflet of Levitra advises heart patients to not take the medicine. This is because Vardenafil could put you at an increased risk of a stroke or a heart attack, especially during sexual intercourse.
  • NitratesAbstain from Vardenafil if you are on nitrates like Monoket, DilatrateSR, or any kind of nitroglycerin drug. You should also avoid any recreational drug which consists of nitrates when taking Vardenafil. Nitrates and Vardenafil are contraindicated and could lead to adverse consequences when they react. You must also refrain from Vardenafil consumption if you’re taking a riociguat such as Adempas for any chest ailments.
  • HypertensionYou should consider staying away from Vardenafil if you are being treated for high blood pressure. Vardenafil may cause a sudden drop in blood pressure which leads to dizziness and even fuzzy vision in some patients. If taken when on a hypertension drug, Vardenafil may cause blood pressure to sink to very low levels, this could be fatal and even lead to coma.
  • Grapefruit JuiceIf you have a stomach for grapefruit juice, you might want to reconsider taking Vardenafil. Grapefruit juice affects the functioning of the drug hence it is advised to consult your doctor if you wish to take Vardenafil with grapefruit juice in your diet.
  • EyesightVardenafil may affect vision in rare cases. As the drug diverts blood from other body parts to the penis this issue occurs. In short, blood flow from the optic nerve is diverted to the penile region. This reduced blood flow to the optic region can lead to a temporary loss in color vision or even shaky vision.
  • Other Miscellaneous RisksPeople who are being treated for HIV or the ones who are taking any antifungal or antibacterial medicines must not take Vardenafil. You should also stay away from Vardenafil if you have ever had multiple myeloma or are being treated for any other kind of cancer. Vardenafil is also not recommended for use for males below the age of 18.
