ZHEWITRA 20

What is ZHEWITRA 20?

ZHEWITRA 20 is a medicinal product intended for the symptomatic treatment of erectile dysfunction in adult men. This condition manifests as the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. The drug is manufactured in the form of tablets for oral use. It is not a hormonal agent and does not directly increase sexual desire.

ZHEWITRA 20 belongs to the pharmacological group of phosphodiesterase type 5 inhibitors, abbreviated as PDE-5. Representatives of this group improve the natural vascular response of the penis to sexual stimulation. The action of the drug is possible only in the presence of sexual arousal, so the tablet does not cause an automatic erection. The product does not cure the cause of the disorder permanently, but helps control its manifestations during the period of action.

The manufacturer of ZHEWITRA 20 is the pharmaceutical company Sunrise Remedies. The drug is positioned as a generic of the vardenafil-based agent with a dosage of 20 mg. The generic contains the same active substance, however, the auxiliary composition, appearance of the tablet, and registration details may differ. Before use, it is necessary to check the official status of the drug in Ukraine, the integrity of the packaging, the expiration date, and the availability of the instructions.

What is ZHEWITRA 20 prescribed for?

The main indication for the use of ZHEWITRA 20 is erectile dysfunction in adult men. This refers to recurrent difficulties in obtaining or maintaining an erection until the completion of sexual intercourse. Vardenafil can be used for disorders of vascular, psychogenic, or mixed origin after a medical examination. An occasional failure does not always mean a disease, but regular symptoms require consultation with a urologist or a family doctor.

The drug can be prescribed to men whose erectile dysfunction is associated with arterial hypertension, diabetes mellitus, atherosclerosis, or age-related vascular changes. In such cases, it is important to simultaneously control the underlying disease, as the tablet does not eliminate its cause. Sexual stimulation is a prerequisite for the development of the therapeutic effect. ZHEWITRA 20 is not intended to increase libido, enlarge penis size, or treat infertility.

Before starting therapy, the doctor must assess the cardiovascular risk, as sexual activity places an additional load on the heart. It is also advisable to identify possible causes of dysfunction, including hormonal disorders, side effects of other medications, and psychological factors. Self-treatment with the maximum dose of 20 mg is undesirable, especially during the first use of PDE-5 group agents. An individually selected regimen provides a better balance of efficacy and safety.

Composition and Active Components of ZHEWITRA 20

The active component of ZHEWITRA 20 is vardenafil at a dose of 20 mg, usually presented in the form of its corresponding salt. The substance selectively inhibits the PDE-5 enzyme, which breaks down cyclic guanosine monophosphate in the tissues of the penis. The preservation of this signaling molecule promotes the relaxation of smooth muscles of the blood vessels and increases blood flow to the corpora cavernosa. This mechanism supports a natural erection in response to sexual arousal.

Auxiliary components form the tablet, ensure its stability, disintegration, and release of vardenafil after swallowing. Their exact list must be checked in the instructions and on the packaging of a specific batch, as the composition may include fillers, binders, colorants, and coating components. Auxiliary substances do not provide the main therapeutic effect but can sometimes cause intolerance reactions. In the presence of allergies or sugar intolerance, the composition should be discussed with a doctor or pharmacist.

Dosage of ZHEWITRA 20

The dose of vardenafil is determined by a doctor, taking into account efficacy, tolerability, age, concomitant diseases, and medications. In many cases, the starting dose is 10 mg approximately 25–60 minutes before anticipated sexual activity. Depending on the response, it may be decreased to 5 mg or increased to the maximum of 20 mg. ZHEWITRA 20 should not be taken more than once within 24 hours.

The drug is used as needed, rather than as an obligatory daily course, unless the doctor has instructed otherwise. The duration of use depends on the cause of erectile dysfunction and the results of periodic medical monitoring. Patients with hepatic impairment, severe renal insufficiency, or an increased risk of hypotension may require a lower dose. Dividing the tablet on your own is permissible only when provided for by its design and official instructions.

How to take ZHEWITRA 20 correctly?

The ZHEWITRA 20 tablet is swallowed with a sufficient amount of water, approximately 25–60 minutes before intimacy. The onset and duration of the effect may vary depending on metabolism, diet, and concomitant diseases. The drug can be taken regardless of food intake, but a very fatty meal can slow down absorption and delay the effect. Grapefruit and grapefruit juice can increase the concentration of vardenafil, so this combination is undesirable.

Since ZHEWITRA 20 is used as needed, the concept of a missed dose does not usually apply. Do not take an extra tablet if the planned sexual contact did not take place or the effect seemed insufficient. It is forbidden to combine the product with other drugs for erection without a doctor's prescription. Consultation with a doctor is mandatory before the first intake, and the individual reaction of the body may vary even with the same dose.

Side effects of ZHEWITRA 20

The most common adverse reactions of vardenafil include headache, facial flushing, nasal congestion, dizziness, and dyspepsia, i.e., stomach discomfort. Nausea, palpitations, back pain, or temporary visual changes are possible. Usually, these manifestations are mild or moderate in nature and pass on their own. Severe or recurrent symptoms require discussion with a doctor and dose adjustment.

Uncommonly, a decrease in blood pressure, tachycardia, allergic rash, dyspnea, or visual impairment may occur. Immediate medical attention is required for chest pain, fainting, sudden loss of vision or hearing, facial swelling, or difficulty breathing. An erection lasting more than four hours is an emergency, as it can damage the tissues of the penis. The risk and severity of side effects depend on the individual reaction of the body, the dose, and drug interactions.

Contraindications of ZHEWITRA 20

ZHEWITRA 20 is contraindicated in case of allergy to vardenafil or any component of the tablet. It must not be combined with nitrates, nitric oxide donors, or riociguat due to the risk of a dangerous drop in blood pressure. The drug is not used in conditions where sexual activity is contraindicated, particularly in unstable angina or severe heart failure. Restrictions may also apply to recent myocardial infarction, stroke, severe hypotension, and certain hereditary retinal disorders.

Special caution is required for men with anatomical deformation of the penis, predisposition to priapism, peptic ulcer disease, bleeding disorders, liver or kidney diseases. ZHEWITRA 20 is not intended for children, adolescents, and women, so pregnancy and breastfeeding issues do not belong to its approved scope of application. Elderly age by itself does not always require correction, but concomitant diseases and polypragmasy increase the risk of reactions. The final decision on the safety of use must be made by a doctor after evaluating the medical history.

Interaction of ZHEWITRA 20 with other drugs and alcohol

The most dangerous interaction is that of ZHEWITRA 20 with nitroglycerin, isosorbide nitrates, other nitrates, and riociguat. Caution is required when using concurrently with alpha-blockers, antihypertensive drugs, certain antibiotics, antifungal drugs, and medications against human immunodeficiency virus. Strong inhibitors of the CYP3A4 enzyme can significantly increase the level of vardenafil in the blood, and certain antiarrhythmic drugs increase the risk of rhythm disturbances. The doctor must be informed about all prescription, over-the-counter, and herbal preparations.

A small amount of alcohol does not always cause a direct interaction, but alcohol can impair erection, worsen dizziness, and lower blood pressure. Excessive consumption of alcohol on the day of intake should be avoided. If dizziness, blurred vision, or weakness occur after taking the tablet, driving and operating machinery are prohibited. Until the individual reaction of the body is clarified, one should refrain from potentially dangerous activities.

Where to buy ZHEWITRA 20 in Ukraine

ZHEWITRA 20 in Ukraine should be purchased only through legal pharmacies or verified online pharmacy services that provide information about the origin and registration status of the product. Before ordering, you should check the manufacturer Sunrise Remedies, the dosage of 20 mg, the batch number, the expiration date, the integrity of the blister, and the delivery conditions. Offers without instructions, labeling, or quality confirmation may carry the risk of counterfeit. The necessity of a prescription and actual availability depend on current requirements and the assortment of a specific pharmacy.

Store the drug in its original packaging, in a dry place, protected from light, moisture, and access of children. The exact temperature regime should be checked with the manufacturer's instructions, preventing overheating or freezing during delivery. Expired or damaged tablets must not be used. Buying ZHEWITRA 20 does not replace a prior consultation with a doctor, as only a specialist can rule out contraindications and select a safe dose.
