Zenegra is a prescription medication containing sildenafil citrate, a potent phosphodiesterase type 5 (PDE5) inhibitor clinically proven to address erectile dysfunction. By enhancing blood flow to the penile tissues during sexual stimulation, it facilitates achieving and maintaining a firm erection suitable for satisfactory sexual activity. This treatment option is designed for adult men experiencing physiological challenges related to erectile performance, offering a reliable and well-researched therapeutic pathway. Proper diagnosis and medical supervision are essential to ensure both safety and efficacy.

Common use

Zenegra is primarily prescribed for the treatment of erectile dysfunction (ED) in adult men. It is used to improve erectile function by increasing blood flow to the penis, enabling a satisfactory erection when sexually aroused. It is not indicated for use by women, adolescents, or individuals without a diagnosis of ED.

Dosage and direction

The typical starting dose is 50 mg taken approximately one hour before anticipated sexual activity. Based on efficacy and tolerability, the dose may be adjusted to 100 mg or reduced to 25 mg. Do not exceed one dose in a 24-hour period. Take with a glass of water; may be taken with or without food, though high-fat meals may delay onset. Sexual stimulation is required for the medication to work.

Precautions

• Not intended for use by women or individuals under 18 years of age.
• Avoid alcohol consumption, as it may increase the risk of side effects such as dizziness or hypotension.
• Use with caution in patients with cardiovascular disease, anatomical deformation of the penis, or conditions predisposing to priapism.
• Inform your healthcare provider of all current medical conditions, including liver or kidney impairment.
• Not a treatment for sexually transmitted infections or a form of contraception.

Contraindications

Zenegra is contraindicated in patients:

• Using any form of organic nitrates or nitric oxide donors (e.g., nitroglycerin, isosorbide mononitrate).
• With a known hypersensitivity to sildenafil or any component of the formulation.
• With severe hepatic impairment, hypotension, or recent history of stroke or myocardial infarction.
• Who have been advised against sexual activity due to underlying cardiovascular risk.

Possible side effects

Common side effects may include:

• Headache
• Flushing
• Dyspepsia
• Nasal congestion
• Dizziness
• Visual disturbances (e.g., changes in color perception)

Rare but serious side effects require immediate medical attention:

• Priapism (prolonged erection lasting more than 4 hours)
• Sudden vision or hearing loss
• Chest pain or irregular heartbeat
• Severe dizziness or fainting

Drug interaction

Zenegra may interact with:

• Nitrates (contraindicated)
• Alpha-blockers (e.g., doxazosin)—risk of hypotension
• Antifungal agents (e.g., ketoconazole) or macrolide antibiotics (e.g., erythromycin)—may increase sildenafil levels
• HIV protease inhibitors (e.g., ritonavir)
• Other PDE5 inhibitors
• Grapefruit juice may increase plasma concentrations

Always inform your prescriber of all medications you are taking, including over-the-counter drugs and supplements.

Missed dose

Zenegra is taken on an as-needed basis. There is no daily dosing schedule; therefore, missed dose protocols do not apply. Do not take an extra dose to make up for a missed occasion.

Overdose

In case of suspected overdose, seek immediate medical attention or contact a poison control center. Symptoms may include severe headache, visual disturbances, dizziness, fainting, or prolonged erection. Standard supportive measures should be applied; hemodialysis is not expected to significantly accelerate elimination.

Storage

Store at room temperature (15–30°C or 59–86°F) in a dry place, protected from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.
