Medicine overview

Penegra 100 mg is an oral medicine containing sildenafil, a phosphodiesterase type 5 (PDE5) inhibitor. It is used to treat erectile dysfunction in adult men. Sildenafil increases blood flow to the penis during sexual stimulation, which can help produce and maintain an erection. Sexual stimulation is still required for the medicine to work. Penegra does not increase sexual desire and does not cure the underlying cause of erectile dysfunction.

What it is used for

Penegra 100 mg is used for the treatment of erectile dysfunction, where a man has difficulty getting or maintaining an erection suitable for sexual activity. Sildenafil supports the normal erectile response by improving penile blood flow when sexual stimulation occurs. This specific Penegra 100 mg product should not be assumed to have the same indications or dosing instructions as sildenafil products formulated and approved for pulmonary arterial hypertension.

How it works

Sildenafil blocks phosphodiesterase type 5 (PDE5), an enzyme involved in breaking down cyclic guanosine monophosphate (cGMP). During sexual stimulation, nitric oxide increases cGMP in erectile tissue. Higher cGMP levels relax smooth muscle and allow more blood to flow into the penis. By slowing the breakdown of cGMP, sildenafil strengthens this natural response. It does not cause an erection without sexual stimulation.

How it is taken

Penegra is swallowed by mouth as directed by the prescriber. For erectile dysfunction, sildenafil is taken as needed before sexual activity; general sildenafil guidance states that it is commonly taken about 1 hour beforehand and may be taken from 30 minutes to 4 hours before sexual activity. It should not normally be taken more than once in 24 hours. It can be taken with or without food, although a high-fat meal may delay its onset of action.

Important warnings

Do not take sildenafil with nitrates such as nitroglycerin, isosorbide mononitrate, or isosorbide dinitrate, or with recreational nitrate/nitrite products (“poppers”), because the combination can cause a dangerous fall in blood pressure. Sildenafil is also contraindicated with guanylate cyclase stimulators such as riociguat. Medical review is particularly important for people with cardiovascular disease, very low or uncontrolled high blood pressure, recent heart attack or stroke, severe liver or kidney problems, bleeding disorders, retinitis pigmentosa, previous non-arteritic anterior ischemic optic neuropathy (NAION), penile deformity, or conditions that increase the risk of priapism. Alpha-blockers and medicines that strongly inhibit CYP3A4 can increase the risk of adverse effects or alter sildenafil exposure. Do not combine it with another PDE5 inhibitor or other erectile-dysfunction treatment unless specifically instructed by a clinician. Seek urgent medical care for chest pain during sexual activity, sudden vision or hearing loss, fainting, a severe allergic reaction, or a painful/prolonged erection lasting more than 4 hours.

Side effects and monitoring

Common sildenafil side effects include headache, flushing, indigestion or heartburn, nasal congestion, nausea, dizziness, and temporary visual changes such as altered color perception or increased sensitivity to light. Serious but less common problems include marked hypotension, fainting, sudden loss or reduction of vision, sudden hearing loss, allergic reactions, and priapism. Cardiovascular events have also been reported, particularly in people with underlying cardiovascular risk. Seek immediate medical attention for chest pain, severe breathing difficulty, sudden vision or hearing changes, or an erection lasting more than 4 hours. Routine laboratory monitoring is not generally required solely for sildenafil used for erectile dysfunction, but clinical review may be appropriate according to underlying health conditions and other medicines.

Pregnancy

Penegra 100 mg is indicated for erectile dysfunction in adult men and is not indicated for use in females. Pregnancy use is therefore not applicable to the approved erectile-dysfunction indication for this product.

Breastfeeding

Penegra 100 mg is indicated for erectile dysfunction in adult men and is not indicated for use in females. Breastfeeding guidance is therefore not applicable to its erectile-dysfunction indication.

Food, drink and interactions

Sildenafil did not increase the blood-pressure-lowering effect of a moderate alcohol dose in a controlled interaction study. However, drinking larger amounts of alcohol can contribute to dizziness, lower blood pressure, and erectile difficulties. Limiting alcohol around the time sildenafil is used is therefore prudent, particularly if dizziness or low blood pressure occurs.

Food and drink

Penegra may be taken with or without food. A high-fat meal can delay sildenafil absorption and may make it take longer to start working. Grapefruit or grapefruit juice may affect sildenafil exposure, so patients should discuss regular grapefruit consumption with their doctor or pharmacist.

Storage

Store the tablets at room temperature, protected from excess heat and moisture, and keep them out of the reach of children. Product listings for Penegra 100 mg specify storage below 25°C.

Frequently asked questions

Does Penegra 100 mg work without sexual stimulation?

No. Sildenafil supports the erectile response when sexual stimulation occurs; it does not automatically cause an erection or increase sexual desire.

How long before sex should I take Penegra?

General sildenafil guidance recommends taking it about 1 hour before sexual activity, although it may be taken between 30 minutes and 4 hours beforehand. Follow the instructions given by your prescriber.

Does eating affect how quickly Penegra works?

Yes, particularly with a high-fat meal. Sildenafil can be taken with or without food, but a high-fat meal may delay absorption and make the medicine take longer to work.

What should I do if Penegra gives me a severe headache or dizziness?

Contact a healthcare professional if these effects are severe or persistent. Seek urgent care for fainting, chest pain, severe breathing problems, or other serious symptoms rather than taking additional sildenafil.

Can I take Penegra with nitrate medicines for chest pain?

No. Sildenafil must not be combined with nitrates because blood pressure can fall to a dangerous level. Tell emergency healthcare professionals when you last took sildenafil if you develop chest pain.

What if an erection lasts more than 4 hours after taking sildenafil?

Seek emergency medical care immediately. A prolonged erection, called priapism, can damage penile tissue if treatment is delayed.

Can Cheap Generic Med ship Penegra 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 may extend transit. Prescription and personal-import requirements may apply.

Will my Penegra order have tracking?

Under the standard Cheap Generic Med 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 show movement in the carrier system.
