Levitra (vardenafil) is a time-tested and effective generic drug that has made a significant breakthrough in the treatment of erectile dysfunction. Due to its unique composition, the drug works quickly and the positive result is achieved in 20-25 minutes. The drug is well tolerated by the body and the probability of adverse effects is practically zero.
Mechanism of action
The main spectrum of action is aimed at relaxing the smooth muscles that make up the man’s cavernous body. As a result, there is a significant increase in blood flow to the male genital organ and ensuring a long erection. The duration of action is up to 10 hours.
Indications for use
Levitra is recommended for men aged 18 to 65 years who have erectile dysfunction and reduced erection caused by age-related changes, lifestyle, fatigue and several other changes.
How to take this medicine?
Take 1 tablet orally with a sufficient amount of liquid, half an hour before the planned intimacy. Meals do not affect concentration of the drug. You can achieve a hard and prolonged erection within 20 minutes after taking the tablet. You can take only 1 tablet per day. Keep in mind that vardenafil only works if there is a natural sexual arousal. If the man is not aroused, then an erection will not occur.
Which Levitra dosage can I take?
The recommended Levitra dosage is 20 mg per day. But if the desired result was not achieved, the amount of vardenafil can be increased to 40 mg per day.
Experts advise not to abuse the drug. It is recommended to take the medicine immedi-ately before sexual intercourse but preferably not every day. However, in some cases, the doctor may recommend a course of treatment. In such situations, the daily dose of vardenafil is 5 mg, regardless of the time of the expected sexual intimacy.
Before using Levitra, especially in large doses, it is necessary to consult an experienced doctor. It is also important to undergo a full physical examination to exclude contraindications to the use of the drug. A health specialist is able to recommend the most optimal dose of medication. In addition, before using the drug, it is important to carefully study the instructions in order to know about the possible consequences of taking these tablets.
If you follow all the doctor’s prescriptions, this will help you achieve the best results.
Dosages of Levitra in various patient groups
The dosage of drug that can be taken depends on the age and general condition of the patient’s body.
You cannot use this drug if you are the age of majority since it is not de-signed for this age group.
Elderly patients can focus on general recommendations for the use of the drug if they do not have special health problems.
If the patient has diseases that are treated with other drugs, the following dosages are recommended:
- Liver problems: if the degree of the disease is mild, then the dosage should not be changed. If the abnormalities in the work of the organ are moderate, then it is recommended to start with a dose of 5 mg per day. Then the dosage can be increased to 10 mg, depending on the particular case (Levitra maximum dosage);
- Kidney disease: The degree of the problem does not matter, the dose is not required to be reduced;
- If a man uses CYP3A4 inhibitors, it is necessary to adjust the dosage of Levitra. If the drug is used together with CYP3A4 ketoconazole or itraconazole, the total dose should not exceed 200 mg per day. If a man con-sumes large doses of inhibitors, then he should not take Levitra;
- If a man takes erythromycin or clarithromycin, then he can take no more than 5 mg of vardenafil per day.
How much Levitra should I take the first time?
The initial dosage of vardenafil should be determined by a doctor. You can also take a half or a quarter tablet to avoid possible unwanted reactions. Thus, if you use this drug for the first time, take a dose of 5 or 10 mg. So, a dose of up to 10 mg is suitable for those who suffer from kidneys and liver problems.
The maximum dose that can be taken per day is 20 to 40 mg, depending on the individual characteristics of the body.
Can it cause side effects?
In general, the product is well tolerated by the body. Vardenafil side effects are usually mild or moderate. Therefore, there is no serious reason for concern. Here are the most common adverse reactions that occur after using this medicine:
- Headache. It is difficult to find a medicine that would not cause it;
- Small dizziness. It occurs rarely, usually with a headache;
- Sensations of a rush of blood or heat on the face or other parts of the head. A common reaction for all PDE-5 inhibitors;
- A runny nose. Unfortunately, it also accompanies all medicines for impotence;
- Nausea and slight indigestion. They also occur very rarely.
Note that this is a complete list of side effects. But Levitra is a completely safe drug. Even compared to other PDE5 inhibitors, it practically does not cause negative symptoms, even with an overdose. But this does not mean that you can just break the rules for taking the medicine. Follow all the requirements and recommendations of the manufacturer, obey the advice of your doctor, and you will have any side effects.
If you violate the schedule and do not follow the dosage, then even the safest medicine can do much harm.
Who should not take Levitra?
Despite the carefully selected composition of the drug, Levitra still has some contraindications for use:
- hypersensitivity to the components of the drug;
- curvature and deformation of the penis;
- unstable blood pressure;
- stomach ulcer;
- a recent heart attack or stroke;
- atherosclerosis and cancer;
- renal failure;
- liver problems;
The drug should not be taken by men under 18 years of age, men over 65 years of age, and women. In any case, before taking these tablets, you should consult a specialist.
When taking Levitra, it is necessary to exclude the use of drugs and chemical compounds, which include HIV prosthesis inhibitors, volatile nitrates and nitric oxide donors. Also, you should not combine vardenafil and other drugs for erectile dysfunction, such as Cialis and Viagra. Such a combination can cause a negative effect on the male body and increase the risk of adverse reactions.
The simultaneous administration of grapefruit or grapefruit juice should be avoided since this can cause an increase in plasma concentration of vardenafil.
An overdose of vardenafil rarely caused significant negative consequences. However, after using 80 mg of the drug per day may cause pain in the lumbar region and other negative reactions.
If you have an overdose of Levitra, you must consult a doctor and follow the usual supportive therapy. In this case, hemodialysis is ineffective since vardenafil is able to bind to plasma proteins and is excreted by the kidneys in minimal quantities.
Before using any drugs to treat erectile dysfunction, consult a doctor who will check your cardiovascular system.
The safety and efficacy of Levitra in combination with other drugs for terectile dysfunction has not been studied, therefore, their combined use is not recommended.
In very rare cases, the drug caused transient loss of vision and non-arteritic ischemic optic neuropathy. If you have a sudden loss of vision, it is necessary to stop taking the drug and urgently consult your doctor.
Before driving vehicles and moving machinery, patients should know how they react to vardenafil drugs.
