How to make Levitra more effective: all you need to know about the drug

What are Levitra side effects, and what Levitra generic has similar effectiveness? What do Levitra reviews say, and where can you buy Levitra? Read on to find out.


What is Levitra used for? Doctors prescribe the drug to men suffering from erectile dysfunction. Bayer Pharmaceuticals is the manufacturer of the drug. The company launched it on the market as an alternative to Viagra in 2003. The FDA approved the drug. In 2018, the company announced stopping the production of Levitra 2.5 mg.

Vardenafil is the active substance of Levitra. The substance is an inhibitor of phosphodiesterase type 5. This enzyme prevents the relaxation of smooth muscles, including those in the penis. This disrupts the organ's blood supply, and a full erection becomes impossible, leading to ED.

Vardenafil blocks the action of PDE-5, relaxes smooth muscles and improves the local blood flow. The drug only works if you are sexually aroused. It cannot cause an erection on its own.

How does the drug maintain an erection

What is the mechanism of action of Levitra?

  • When a healthy male experiences sexual arousal, the brain sends a signal that stimulates the release of nitric oxide. The products of its breakdown relax the muscles of the penis, starting blood flow to the cavernous bodies of the penis. When filled with blood, the latter provides an erection.
  • In the case of ED, this mechanism is disrupted. The penis tissue contains PDE-5, which breaks down substances formed because of nitric oxide breakdown. As a result, muscle relaxation does not happen. This prevents the cavernous bodies from filling with blood.
  • The active ingredient of Levitra blocks PDE-5, allowing substances formed due to nitric oxide breakdown to relax the muscles of the penis.

Other PDE-5 inhibitors work similarly. They help improve the blood supply to the penis. But without an appropriate signal from the brain, the drugs will not work. So, it is advisable to take them only when sexually aroused.

Drug dosage forms and doses

Levitra is available as film-coated tablets of 5 mg, 10 mg and 20 mg. You should take the pill with enough water so that it quickly dissolves in the stomach.

How to take Levitra

You should take the drug as needed, 30–60 minutes before sex. The recommended dosage is 10 mg, but depending on the effect and individual characteristics, you can reduce the dose to 5 mg or increase it to the maximum allowed dosage of 20 mg. The drug lasts 4–5 hours, and an erection is possible during this time.

A doctor may prescribe the minimum dosage of 5 mg in cases of mild to moderate hepatic impairment and severe kidney disorder. The dose adjustment is also possible depending on other drugs you take. You can take only one Levitra tablet a day, before or after meals.

If you have no effect or the effect is insufficient, you should not increase the dosage or the number of tablets on your own so as not to provoke an overdose with the drug. Only a doctor should prescribe an appropriate dosage in each case.

How to make Levitra be more effective? To do this, follow simple rules:

  • Follow the doctor's recommendations and instructions for the drug.
  • When taken on an empty stomach, the drug's effect onsets faster.
  • If you take the pill after a meal, avoid fatty foods that may reduce the effectiveness of Levitra.

Possible side effects

Usually, Levitra side effects are minor and easily tolerated. Most often, you may have them at the start of treatment until the body adapts to Vardenafil. Most men taking the drug complain of:

  • Headache
  • Nasal congestion
  • Skin redness and a feeling of heat
  • Dizziness
  • Stomach upset
  • Nausea
  • Back pain, etc.

More serious Levitra side effects include:

  • Chest tightness and pain
  • Mental fog
  • Labored breathing
  • Vision loss
  • Hearing loss
  • Prolonged, painful erection
  • Fainting
  • Vomiting
  • Weakness, etc

Such reactions to the drug are rare enough, but you should ignore none of the above symptoms since it can be a sign of a severe pathology. If you experience any of these side effects, contact your doctor immediately.


An overdose with the drug can cause an increase in side effects. During the study of the drug, when using a dosage of 40 mg and 80 mg, no serious side effects were observed. A single dose of 120 mg led to visual impairment, back pain and myalgia. The severity of reactions after an overdose depends on individual characteristics. So, you should immediately consult a doctor if you have exceeded the prescribed dosage.


Although Levitra is usually well tolerated, in some cases, taking this drug is contraindicated. These include:

  • Increased sensitivity to Vardenafil or other components of the drug
  • Contraindication to sex due to a severe heart disease
  • Vision loss or non-arterial anterior ischemic optic neuropathy

In some conditions, the effect of the drug has not been studied. For example, you should avoid using it in the case of:

  • Severe liver or kidney diseases requiring dialysis
  • Decreased blood pressure
  • A stroke or heart attack within the last 6 months
  • Hereditary degenerative disease of the retina
  • Unstable angina pectoris

You should use the drug with caution if you are over 65. Before taking the drug, inform the doctor about all concomitant diseases to avoid deterioration of health during treatment.

Things not to combine with the drug

Levitra is incompatible with grapefruit juice as it increases the side effects of the drug. During treatment, also avoid alcohol, which can increase the hypotonic effect of Vardenafil. Additionally, you should avoid taking Levitra together with some drugs, including:

  • Nitrates used to treat angina pectoris
  • Ketoconazole and Itraconazole for fungal infections
  • HIV protease inhibitors such as Ritonavir or Indinavir
  • Guanylate cyclase stimulants for the treatment of pulmonary hypertension
  • Other PDE-5 inhibitors

Tell your doctor about all medications you are using. The doctor will give detailed recommendations regarding the possibility of taking them together with Levitra.

Viagra vs Levitra

Levitra and Viagra are PDE-5 inhibitors and have similar effects. By relaxing the muscles of the penis, the drugs increase blood flow in the organ, causing an erection. This mechanism of action allows the use of both drugs for the treatment of erectile dysfunction. Are there any differences between them?

As you can see, the drugs have similar action and effectiveness. At the same time, you can buy Levitra at a lower price compared to Viagra. And for many, it is a determining factor. For some men, individual intolerance may affect the choice of drug since the active substance is different.

Levitra is a stronger drug. So, you should use lower dosages for treatment compared to Viagra. The maximum dosage of Levitra is 20 mg, while the maximum dosage of Viagra is 100 mg. You should not combine these two drugs.

Levitra generic

For the treatment of erectile dysfunction, you can use a Levitra generic, Vardenafil, containing the same active substance. It has all the qualities of Levitra and can cause similar side effects. All recommendations for Levitra are valid for its generic. This drug has a proven efficacy and is safe for use when doctor's instructions and prescriptions are followed.

Vardenafil is available in 5 mg, 10 mg and 20 mg tablets. You should take the tablet 30–60 minutes before sex, and the drug action lasts 4–5 hours. Do not take more than one tablet of Vardenafil a day. For many, the generic Levitra cost is an attractive factor. Usually, it is lower than that of the original drug, which makes the generic more affordable.

Where to buy Levitra

What are Levitra reviews?

More than 70% of those who took Levitra are happy with the result. And just over 10% of those who left a review reported a negative experience. Both young and older men note the benefits of the drug. To improve effectiveness, users recommend taking Levitra on an empty stomach. There are also positive reviews about long-term treatment with the drug. The reviews also say you can have the maximum effect of the drug within 60 minutes after taking it.

Can Levitra treat the cause of ED?

While Levitra effectively deals with the symptoms of erectile dysfunction, it does not affect the cause of this disease. ED is often the result of an underlying disease adversely affecting the blood vessels or caused by psychological problems.

Levitra helps to fix the sexual life. But erection problems will not go away if you will not eliminate their cause. If you want to remove the true cause of the disease, you should undergo a thorough examination and pass the necessary tests. Treating the underlying disease can help get rid of ED for a long time.

Can women use Levitra?

Levitra is for the treatment of the symptoms of ED and is not suitable for use in women. The drug may cause side effects. And there are no studies on its effect during pregnancy and lactation. However, according to some data, the drug increases blood flow to the genitals of women contributing to sexual arousal.

But considering that women and men have different mechanisms of sexual satisfaction, Levitra will not provide the desired effect when taken by a woman. In the case of female sexual disorders, doctors recommend specially designed drugs with proven effectiveness.

Who can have the biggest benefits from Levitra?

All those who have erectile dysfunction benefit from taking the drug. But it is especially useful for people with various kinds of vascular pathologies when the blood flow in the penis is difficult due to the underlying disease. These are such conditions, as:

  • Diabetes
  • Hypertension
  • High blood cholesterol

Risk of priapism

In rare cases, Levitra can cause a prolonged, painful erection lasting more than 4 hours. This condition is also known as priapism and requires immediate medical help.

Otherwise, it can lead to irreversible damage to the tissues of the penis and loss of potency. You should use the drug with caution in the case of anatomical deformity of the penis or other conditions with a tendency to priapism.

Visual impairment from Levitra

In some cases, while taking the drug, there may be a visual impairment caused by a drop in blood pressure in the eye. This leads to the impaired perception of blue and green colors giving things a bluish tint.

Usually, this side effect affects one eye and is extremely rare in both eyes. You should rule out diseases, such as diabetes, hypertension, or high cholesterol, if both eyes are affected. This side effect is more common in men over 50 and smokers. You should immediately consult a doctor, if you have vision problems during Levitra treatment.

At what age can you use Levitra?

The drug is not recommended for men under 18 years of age. Those over 65 should also use the drug with caution, as Vardenafil reaches a higher concentration in their blood. In this regard, it is recommended to consider a dosage of up to 5 mg to prevent side effects.

Does Levitra protect from STDs?

Levitra is a PDE-5 inhibitor and has no effect over sexually transmitted infections (STDs). You should take additional measures to avoid infection.

Can healthy men use the drug?

If you do not have erection problems, do not use the drug for fun. You may have side effects without changing the quality of your erection. If you use the drug regularly without medical indications, you can get psychologically addicted to it, which can lead to erectile dysfunction over time.

Does Levitra prevent pregnancy?

Levitra is not a contraceptive. It improves blood flow in the penis but does not affect sperm quality or other characteristics. A man taking the drug can make his partner pregnant, if intimacy happens at the right time for conception. If you do not plan pregnancy, use contraceptives.
