What is ZIDENA 100 mg?
ZIDENA 100 mg is a medicinal product for the treatment of erectile dysfunction in adult men, which is the inability to achieve or maintain an erection sufficient for sexual intercourse. The product belongs to the class of phosphodiesterase type 5 inhibitors, abbreviated as PDE-5. It enhances the body's natural response to sexual arousal, but does not cause an erection without sexual stimulation. The drug is not a hormonal agent, an aphrodisiac, or a method to increase fertility.
ZIDENA 100 mg is available in the form of film-coated tablets for oral administration. Each tablet contains a dose of udenafil calculated for occasional use before expected sexual activity. The effect usually develops gradually and can last for a long time, but the actual onset and duration of the effect depend on the state of health, food intake, and the individual response of the body. The drug should only be used in accordance with the official instructions and doctor's recommendations.
Information about the manufacturer must be verified on the specific packaging, as the supplier or the holder of the registration certificate may vary depending on the batch and market. Before purchasing, you should ensure the presence of Ukrainian labeling, batch number, expiration date, and proper integrity of the blister pack. Consultation with a doctor before taking the drug is mandatory, especially in the presence of cardiovascular diseases or ongoing drug therapy. Self-treatment can be dangerous due to possible contraindications and drug interactions.
Why is ZIDENA 100 mg prescribed?
The main indication for use is erectile dysfunction in adult men. This condition can manifest as insufficient hardness of the penis, difficulty in achieving an erection, or its premature loss. ZIDENA 100 mg helps to improve blood flow to the cavernous bodies during sexual arousal. Natural sexual stimulation is required for the therapeutic effect to develop.
The drug can be prescribed for erectile dysfunction of vascular, psychogenic, or mixed origin after a medical examination. Udenafil does not eliminate the direct cause of the disorder, so it is important to evaluate blood pressure, glucose levels, lipid profile, hormonal status, and psychological factors. Erectile dysfunction is sometimes an early sign of atherosclerosis, diabetes mellitus, or another systemic disease. Treatment should be combined with the correction of identified risk factors.
ZIDENA 100 mg is not intended for women, children, or adolescents, and does not protect against sexually transmitted infections. The product is also not a contraceptive and does not directly affect sexual desire. Efficacy and tolerability are individual, so the absence of a result after a single dose does not always mean the treatment is ineffective. You must not change the dose or combine the drug with other products for erection without consulting a doctor.
Composition and active components of ZIDENA 100 mg
The active substance of ZIDENA 100 mg is udenafil at a dose of 100 mg. It selectively inhibits the PDE-5 enzyme, which breaks down cyclic guanosine monophosphate in the tissues of the penis. During sexual stimulation, this promotes the relaxation of vascular smooth muscles and increases blood flow to the cavernous bodies. Udenafil does not initiate this process on its own, so without arousal, the expected effect will not occur.
The tablet also contains excipients necessary for core formation, drug stability, disintegration, and film coating. They do not provide the main therapeutic effect, but may be important for people with allergies or intolerance to individual components. The exact list of excipients should be checked against the instructions and labeling of the specific packaging. In the presence of a known hypersensitivity to udenafil or excipients, the drug is not used.
Dosage of ZIDENA 100 mg
The usual recommended dose for an adult man is 100 mg once before anticipated sexual activity. The tablet is typically taken approximately 30 minutes before intercourse, taking into account the individual time required for the effect to develop. The maximum recommended frequency is no more than once a day. Exceeding the dose does not guarantee a stronger erection, but increases the risk of adverse reactions.
Depending on the efficacy, tolerability, concomitant diseases, and medications, the doctor may change the treatment regimen within the doses provided by the official instructions. It is not recommended to split the tablet, increase the dosage, or repeat the intake within 24 hours on your own. ZIDENA 100 mg is usually used as needed, rather than as a continuous course of fixed duration. The periodic need for treatment and its effectiveness should be evaluated by a doctor.
Dose adjustment may be required for patients with impaired hepatic or renal function, low blood pressure, and other significant conditions. Special caution is required when used concomitantly with drugs that affect the metabolism of udenafil. Before starting therapy, the doctor assesses whether physical exertion associated with sexual activity is safe for the patient. A regimen prescribed for another person should not be used as a universal recommendation.
How to take ZIDENA 100 mg correctly?
The tablet is swallowed whole with a sufficient amount of water. ZIDENA 100 mg can be used regardless of food intake, however, a heavy or very fatty meal may delay the onset of action in some patients. Do not chew or crush the tablet unless otherwise specified in the instructions. For a more predictable result, it is advisable to avoid overeating before taking the drug.
Since the drug is used as needed, the concept of a missed dose is usually not applicable. If a planned dose is missed, there is no need to take a double dose or two tablets in a row. The next dose is used only when necessary and in compliance with the minimum interval specified in the instructions. In the absence of an effect, you must not additionally take another PDE-5 inhibitor.
Before starting use, it is necessary to inform the doctor about all chronic diseases, surgeries, allergies, prescription, and over-the-counter medicines. In case of a sudden worsening of well-being during intercourse, you should stop the physical activity and seek medical help. It should be taken into account that the individual response of the body may differ even with the same dose. Consultation with a doctor before taking the drug helps to reduce the risk of serious complications.
Side effects of ZIDENA 100 mg
Common or clinically expected adverse reactions of PDE-5 inhibitors include headache, facial flushing, nasal congestion, hot flashes, and dyspepsia. Dizziness, abdominal discomfort, palpitations, red eyes, or temporary changes in visual perception are possible. Usually, such manifestations are mild or moderate in nature and pass on their own. If the symptoms are pronounced, repeat, or worsen, a doctor's consultation is required.
Infrequently, low blood pressure, weakness, nausea, chest pain, heart rhythm disturbances, or allergic manifestations may occur. The risk of hypotension increases when combined with alcohol, vasodilators, or certain drugs for hypertension. In case of dizziness, you should sit or lie down and avoid standing up suddenly. Any reaction depends on the dose, concomitant therapy, and individual sensitivity.
Immediate medical attention is required in case of an erection lasting more than four hours, sudden loss of vision or hearing, fainting, facial swelling, or difficulty breathing. Chest pain during or after intercourse also requires urgent examination. In such a situation, you must not take nitrates on your own to relieve pain. Medical staff must be informed when exactly udenafil was taken.
Contraindications of ZIDENA 100 mg
An absolute contraindication is hypersensitivity to udenafil or any component of the tablet. ZIDENA 100 mg must not be combined with nitrates or nitric oxide donors due to the risk of a dangerous drop in blood pressure. The drug is also not used if sexual activity is contraindicated due to a severe cardiovascular condition. Restrictions may apply to recent myocardial infarction, stroke, unstable angina, severe hypotension, or uncontrolled hypertension.
Relative contraindications or conditions requiring special evaluation include severe liver or kidney dysfunction, anatomical deformation of the penis, and predisposition to priapism. Caution is required in patients with peptic ulcer disease, bleeding disorders, severe arrhythmias, and hereditary retinal diseases. Patients with a history of vision loss due to optic nerve damage require an individual consultation with an ophthalmologist and a physician. The final decision depends on the balance of expected benefits and risks.
The drug is not intended for women, so it is not used during pregnancy or breastfeeding. ZIDENA 100 mg is contraindicated in persons under 18 years of age due to the lack of properly established safety and efficacy. Elderly men do not always require an automatic dose reduction, but concomitant diseases and multiple medications increase the risk of interactions. Before use in older age, an assessment of the cardiovascular state is particularly important.
Interaction of ZIDENA 100 mg with other drugs and alcohol
ZIDENA 100 mg is categorically not combined with nitroglycerin, isosorbide mononitrate, isosorbide dinitrate, and other nitrates. Caution is required when using alpha-blockers, antihypertensive drugs, and potent CYP3A4 enzyme inhibitors, which can increase the concentration of udenafil. Such agents include certain antifungal, antiviral drugs, and some antibiotics, so a complete list of therapy should be provided to the doctor. Simultaneous use with other drugs for the treatment of erectile dysfunction is not recommended.
Alcohol can increase dizziness, low blood pressure, and palpitations, and in large quantities, it impairs erection itself. For the duration of the drug's action, it is advisable to avoid alcohol or limit its consumption as much as possible. If dizziness, visual impairment, weakness, or slowed reactions occur, you must not drive vehicles or work with mechanisms. Even in the absence of symptoms, the first dose should be planned in a way to assess individual tolerability in safe conditions.
