Medicine overview

Zenegra 50 mg is an oral medicine containing sildenafil citrate 50 mg, manufactured by Alkem Laboratories Limited. The manufacturer lists Zenegra under its erectile dysfunction range and supplies this strength in packs of four tablets. Sildenafil belongs to the phosphodiesterase type 5 (PDE5) inhibitor class. It is used to treat erectile dysfunction in adult men by improving the normal erectile response to sexual stimulation. Sexual stimulation is still required for the medicine to work.

What it is used for

Zenegra 50 mg is used for erectile dysfunction, meaning difficulty achieving or maintaining a penile erection sufficient for satisfactory sexual activity. Sildenafil supports an erection when sexual stimulation occurs; it does not produce an erection independently of sexual arousal. The 50 mg Zenegra product should not be treated as interchangeable with sildenafil products intended for other indications or with other Zenegra strengths.

How it works

During sexual stimulation, nitric oxide released in erectile tissue increases cyclic guanosine monophosphate (cGMP), which relaxes smooth muscle and allows more blood to enter the penis. Sildenafil inhibits phosphodiesterase type 5 (PDE5), the enzyme that normally breaks down cGMP. By slowing this breakdown, sildenafil strengthens the natural erectile response to sexual stimulation and helps make it easier to achieve and maintain an erection.

How it is taken

Zenegra 50 mg is taken by mouth. General sildenafil guidance for erectile dysfunction is to take it as needed before anticipated sexual activity; sildenafil 50 mg is commonly taken about 1 hour beforehand and may be taken between 30 minutes and 4 hours before sexual activity. It should not be taken more than once in 24 hours. It can be taken with or without food, although a high-fat or heavy meal can delay how quickly it starts working. Follow the instructions provided by the prescriber or product leaflet rather than changing the dose yourself.

Important warnings

Do not use sildenafil with nitrates or nitric oxide donors, including medicines such as nitroglycerin, because the combination can cause a dangerous fall in blood pressure. It is also contraindicated with guanylate cyclase stimulators such as riociguat. Tell the prescriber about alpha-blockers, blood-pressure medicines, strong CYP3A4 inhibitors, other erectile-dysfunction treatments, and all other medicines or supplements being used. Medical assessment is particularly important for people with significant cardiovascular disease, recent heart attack or stroke, low blood pressure, severe liver or kidney impairment, bleeding disorders, penile deformity, blood disorders that predispose to priapism, or certain retinal/optic-nerve disorders. Sexual activity itself may pose a cardiovascular risk for some people with heart disease. Seek urgent medical attention for an erection lasting more than 4 hours, sudden loss of vision or hearing, severe allergic symptoms, or significant chest symptoms during sexual activity.

Side effects and monitoring

Common sildenafil side effects include headache, flushing, indigestion, nasal congestion, dizziness, nausea and temporary visual disturbances such as blurred vision or changes in color perception. Less common but potentially serious reactions include prolonged or painful erection, sudden vision loss, sudden decrease or loss of hearing, severe low blood pressure, cardiovascular events and hypersensitivity reactions. Obtain urgent medical care for an erection lasting more than 4 hours, sudden vision or hearing changes, severe chest symptoms, fainting, or signs of a serious allergic reaction. Routine laboratory monitoring is not generally specified for sildenafil used as needed for erectile dysfunction, but underlying cardiovascular health and interacting medicines should be assessed as clinically appropriate.

Pregnancy

Zenegra 50 mg is indicated for erectile dysfunction in adult men and is not indicated for use in women. Sildenafil pregnancy information from other indications should not be used to justify taking this ED product during pregnancy.

Breastfeeding

Zenegra 50 mg for erectile dysfunction is not indicated for use in women. Limited data from sildenafil use in other settings indicate that sildenafil and its active metabolite can be present in human milk, but information about effects on a breastfed child or milk production is insufficient.

Food, drink and interactions

Avoid excessive alcohol before sexual activity while using sildenafil. Large amounts of alcohol can make it more difficult to achieve an erection and may add to effects such as dizziness or lowered blood pressure.

Food and drink

Sildenafil can be taken with or without food. A high-fat or heavy meal may delay its absorption and make it take longer to start working. Avoid grapefruit and grapefruit juice because they can affect sildenafil metabolism and may increase the likelihood of side effects.

Storage

Store sildenafil tablets at room temperature, away from excess heat and moisture, and keep them out of reach of children. The U.S. sildenafil reference product specifies controlled room temperature at 25°C (77°F), with permitted excursions between 15°C and 30°C (59°F to 86°F).

Frequently asked questions

Does sildenafil work without sexual stimulation?

No. Sildenafil supports the normal erectile response, but sexual stimulation is still required for an erection.

Why does Zenegra sometimes seem to take longer to work after eating?

A heavy or high-fat meal can delay sildenafil absorption, so it may take longer to start working.

Can I take Zenegra with nitrate medicine for chest pain?

No. Sildenafil must not be combined with nitrates or nitric oxide donors because blood pressure can fall dangerously low.

What should I do if an erection lasts more than 4 hours?

Seek emergency medical attention. A prolonged erection, called priapism, can damage penile tissue if it is not treated promptly.

Can drinking alcohol affect sildenafil?

Yes. Excessive alcohol can make it harder to achieve an erection and may worsen effects such as dizziness, so large amounts should be avoided.

Can I take another sildenafil tablet if the first one does not work?

Do not take more than one sildenafil dose in a 24-hour period unless a healthcare professional has specifically provided different instructions. Do not increase the dose yourself.

Does Cheap Generic Med ship Zenegra to the United States?

Cheap Generic Med serves the United States under its international shipping model. Delivery is typically estimated at 10–14 business days after dispatch, but customs or carrier delays can extend transit; shipping availability does not establish that personal import is lawful.

Will a Cheap Generic Med order have tracking?

Under the standard fulfilment model, tracked international shipping is used and a tracking number should be provided after dispatch. New tracking numbers may take 24–72 hours to begin showing movement in the carrier system.
