What is VIAGRA 150 mg?
VIAGRA 150 mg is a sildenafil-based medication proposed for the correction of erectile dysfunction in adult men. Sildenafil belongs to the class of phosphodiesterase type 5 inhibitors, which are agents that improve blood flow to the penis in response to sexual stimulation. Most commonly, the medication is presented as tablets for oral administration, although the appearance and composition of the coating depend on the specific supplier. VIAGRA 150 mg does not increase sexual desire and does not cause an erection without sexual excitement.
The 150 mg dose exceeds the standard maximum recommended dose of original sildenafil for the treatment of erectile dysfunction, which is typically 100 mg per day. Therefore, VIAGRA 150 mg should not be used to independently enhance the effect or after an unsuccessful attempt with a lower dose. Increasing the amount of sildenafil may raise the risk of low blood pressure, vision disorders, headaches, and prolonged painful erections. Before taking the medication, a doctor's consultation, cardiovascular evaluation, and check for compatibility with other medicines are required.
The manufacturer is not specified in the provided information, making it impossible to confirm the origin, registration status, and compliance of the specific packaging with quality standards. The name VIAGRA is typically associated with the original brand of sildenafil, but the 150 mg dosage requires particularly careful verification of the labeling and official instructions. The drug should only be purchased from a licensed pharmacy, where the manufacturer, batch number, expiration date, and dispensing conditions can be verified. The information in this description does not replace a doctor's prescription and the instructions for the specific purchased package.
What is VIAGRA 150 mg prescribed for?
The main indication for sildenafil is erectile dysfunction, which is the persistent inability to achieve or maintain an erection sufficient for sexual intercourse. The medication facilitates the natural vascular response to sexual stimulation but does not eliminate all possible causes of the disorder. Erectile dysfunction can be linked to cardiovascular diseases, diabetes mellitus, neurological disorders, hormonal changes, or psychological factors. This is why it is advisable to undergo a medical examination before starting treatment.
VIAGRA 150 mg is sometimes offered to men with an insufficient response to lower doses of sildenafil, but this practice does not align with the standard regimen for self-administration. The lack of effect after taking a tablet can be explained by eating too much fatty food, insufficient stimulation, incorrect timing of administration, or severe organic pathology. In such a situation, it is safer to review the diagnosis and treatment plan with a urologist or andrologist rather than increasing the dose. The doctor may also suggest another phosphodiesterase type 5 inhibitor or an alternative therapy method.
Sildenafil is also used for pulmonary arterial hypertension, but other dosages and special regimens under the supervision of a specialist doctor are used for this purpose. VIAGRA 150 mg should not be taken independently for this purpose. The agent is not intended to increase stamina, enlarge the penis, or for prophylactic use by healthy men. The expected result depends on the cause of the disorder, general health, and individual body response.
Composition and active components of VIAGRA 150 mg
The declared active component of VIAGRA 150 mg is sildenafil, usually presented in the form of citrate in an amount equivalent to 150 mg of sildenafil. It selectively inhibits the phosphodiesterase type 5 enzyme and slows down the breakdown of cyclic guanosine monophosphate. As a result, the smooth muscles of the penile blood vessels relax, and blood flow increases during sexual stimulation. The mechanism does not work fully without the release of nitric oxide, which occurs during excitement.
Excipients provide the shape, stability, dissolution, and coating of the tablet, but their exact list depends on the manufacturer. The composition of such tablets may include cellulose, calcium phosphates, croscarmellose sodium, magnesium stearate, hypromellose, and colorants. Since the manufacturer is not specified, the specific composition must be checked in the official instructions on the packaging. This is especially important in the presence of allergies, lactose intolerance, or sensitivity to colorants.
Dosage of VIAGRA 150 mg
For most adult men, the usual starting dose of sildenafil for erectile dysfunction is 50 mg approximately one hour before sexual activity. Depending on efficacy and tolerability, the doctor may reduce it to 25 mg or increase it to the standard maximum dose of 100 mg. Sildenafil should be taken no more than once a day. VIAGRA 150 mg exceeds this usual maximum, so taking a whole tablet without a direct medical prescription is dangerous.
A continuous course on a fixed schedule is usually not required for the treatment of erectile dysfunction: the medication is used as needed. Dose adjustment is necessary for older adults, patients with severe renal or hepatic impairment, as well as those taking certain antiviral or antifungal agents. The tablet should only be split if permitted by the instructions and if it has a score line designed for splitting. Arbitrary combination of tablet parts or repeated administration within a day increases the risk of overdose.
How to take VIAGRA 150 mg correctly?
The tablet is swallowed with water, usually about 30–60 minutes before anticipated sexual activity. The effect may start later, and its duration often reaches about four hours, but this does not mean a continuous erection. Fatty and heavy meals can slow down the absorption of sildenafil and delay the effect. Sexual stimulation remains a necessary condition for the drug to work.
Since the medication is taken as needed, the concept of a missed dose does not usually apply. The lack of effect cannot be compensated for by taking an additional tablet on the same day. Before taking VIAGRA 150 mg for the first time, it is necessary to consult a doctor, especially in the presence of chest pain, shortness of breath, fainting, or a history of heart disease. The individual response of the body may vary, so efficacy and tolerability cannot be guaranteed in advance.
Side effects of VIAGRA 150 mg
Common adverse reactions of sildenafil include headache, hot flashes, nasal congestion, heartburn, nausea, and dizziness. Temporary blurred vision, increased sensitivity to light, or a bluish tinge to vision are possible. Palpitations, blood pressure fluctuations, vomiting, rash, muscle pain, or nosebleeds occur uncommonly. The likelihood and severity of side effects may increase with higher doses.
Immediate medical attention is required for an erection lasting more than four hours, sudden loss of vision or hearing, seizures, fainting, or a severe allergic reaction. Chest pain during sexual activity also requires stopping the exertion and seeking urgent help. Nitrates to relieve such pain must not be taken after sildenafil due to the risk of a critical drop in blood pressure. For any unusual or persistent symptoms, further use should be agreed with a doctor.
Contraindications of VIAGRA 150 mg
The combination of sildenafil with nitrates, nitric oxide donors, and the guanylate cyclase stimulator riociguat is absolutely contraindicated. The drug is not used in case of allergy to its components, severe hypotension, or when sexual activity is prohibited due to an unstable cardiovascular state. Special caution is required after a recent myocardial infarction or stroke, in severe hepatic impairment, and hereditary degenerative retinal diseases. Previous loss of vision due to non-arteritic anterior ischemic optic neuropathy is also a significant warning.
Relative contraindications include anatomical deformation of the penis, sickle cell anemia, multiple myeloma, leukemia, peptic ulcer disease, and a predisposition to bleeding. VIAGRA 150 mg is not intended for children, adolescents, and women, so the issue of pregnancy and breastfeeding does not apply to this indication. Older men may require a lower starting dose due to concomitant diseases and slower clearance of the drug. The final decision is made after evaluating the benefits, risks, and all medications used by the patient.
Interaction of VIAGRA 150 mg with other medicines and alcohol
VIAGRA 150 mg is incompatible with nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and recreational nitrates. Alpha-blockers and antihypertensive drugs can increase dizziness and blood pressure drops, so a stable condition and dose adjustment are required. Ritonavir, clarithromycin, erythromycin, ketoconazole, and itraconazole can increase the concentration of sildenafil, while some hepatic enzyme inducers can weaken its effect. The drug should not be combined with other remedies for erectile dysfunction.
Alcohol does not have a direct absolute incompatibility with sildenafil, but it can impair erection, worsen headache, dizziness, and blood pressure drops. Excessive alcohol consumption against the background of a high dose of the drug is particularly dangerous. In case of vision impairment, dizziness, or weakness, you must not drive vehicles or work with machinery. Until the individual response of the body is determined, one should refrain from potentially dangerous activities.
Where to buy VIAGRA 150 mg in Ukraine
You should search for VIAGRA 150 mg in Ukraine only in licensed brick-and-mortar or online pharmacies with legitimate delivery of medicines. Before purchasing, it is necessary to check the state registration of the specific drug, the name of the manufacturer, packaging integrity, batch number, expiration date, and the presence of Ukrainian-language instructions. The absence of information about the manufacturer or an offer without proper labeling may indicate a questionable origin of the product. The dispensing conditions are determined by the current requirements and registration documents of the specific product.
Tablets should be stored in their original packaging, in a dry place inaccessible to children, at the temperature specified by the manufacturer. During delivery, it is important to avoid overheating, moisture, and damage to the blister pack.

Self-treatment with VIAGRA 150 mg can be dangerous, even if drugs with a lower sildenafil content were previously well tolerated.
