Medicine overview

Spegra 100 Mg Tablet contains sildenafil, supplied as sildenafil citrate, and is used to treat erectile dysfunction in adult men. Sildenafil belongs to the phosphodiesterase type 5 (PDE5) inhibitor class. It improves the natural erectile response by increasing blood flow to the penis when sexual stimulation occurs. The 100 mg strength is the maximum recommended sildenafil dose for erectile dysfunction and should be used only as directed by the prescriber. Sildenafil does not increase sexual desire and does not produce an erection without sexual stimulation.

What it is used for

Spegra 100 Mg Tablet is used for erectile dysfunction, a condition in which a man has difficulty achieving or maintaining an erection sufficient for satisfactory sexual activity. Sildenafil helps improve erectile function when sexual stimulation is present. This product should not be treated as interchangeable with sildenafil formulations intended for pulmonary arterial hypertension, because their indications and dosing instructions differ.

How it works

Sildenafil inhibits phosphodiesterase type 5 (PDE5), an enzyme that normally breaks 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 enter the penis. By slowing the breakdown of cGMP, sildenafil strengthens this natural response and can make it easier to achieve and maintain an erection. Sexual stimulation is still required for the medicine to work.

How it is taken

Take Spegra by mouth according to the prescriber's instructions. Sildenafil for erectile dysfunction is generally taken as needed about 1 hour before sexual activity and may be taken between 30 minutes and 4 hours beforehand. Do not take sildenafil more than once in 24 hours. It may be taken with or without food, although a high-fat or large meal can delay its onset of action. The 100 mg strength is the maximum recommended dose; do not take additional sildenafil or another erectile-dysfunction medicine unless specifically instructed by a clinician.

Important warnings

Do not use sildenafil with nitrates such as nitroglycerin or isosorbide, nitric-oxide donors, or recreational nitrites ("poppers"), because the combination can cause a dangerous fall in blood pressure. Sildenafil is also contraindicated with riociguat. Tell the prescriber about alpha-blockers, blood-pressure medicines, strong CYP3A4 inhibitors, other PDE5 inhibitors, and all other medicines or supplements. Medical assessment is particularly important with cardiovascular disease, recent heart attack or stroke, low blood pressure, severe liver or kidney impairment, bleeding disorders, penile deformity, or conditions that predispose to priapism. Seek urgent medical care for an erection lasting more than 4 hours, sudden loss or marked reduction of vision or hearing, chest pain, fainting, or a severe allergic reaction. Patients advised to avoid sexual activity because of cardiovascular risk should not use sildenafil for erectile dysfunction.

Side effects and monitoring

Common effects include headache, flushing, indigestion, nasal congestion, dizziness, nausea, back or muscle discomfort, and temporary visual changes such as altered color perception or blurred vision. Less common but serious reactions include severe hypotension, cardiovascular events, sudden hearing loss, non-arteritic anterior ischemic optic neuropathy causing sudden vision loss, and priapism. Obtain urgent medical attention for an erection lasting more than 4 hours, sudden vision or hearing changes, chest pain, fainting, or signs of a severe allergic reaction. Routine laboratory monitoring is not generally required solely because sildenafil is being used, but underlying cardiovascular and other medical conditions may require clinical assessment.

Pregnancy

Spegra 100 Mg Tablet for erectile dysfunction is not indicated for use in females. There are no adequate human pregnancy data for sildenafil in this indication.

Breastfeeding

Spegra 100 Mg Tablet for erectile dysfunction is not indicated for use in females. Limited evidence indicates 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. Large amounts of alcohol can make it more difficult to achieve an erection and may add to symptoms such as dizziness or light-headedness.

Food and drink

Sildenafil may be taken with or without food. A high-fat or large meal can delay how quickly it begins to work. Avoid grapefruit and grapefruit juice because they can affect sildenafil metabolism and may increase the likelihood of side effects.

Frequently asked questions

Does sildenafil work without sexual stimulation?

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

How long before sex should I take sildenafil?

Sildenafil for erectile dysfunction is generally taken about 1 hour before sexual activity, although it may be taken from 30 minutes to 4 hours beforehand. Follow the instructions given by your prescriber.

Can I take Spegra 100 Mg after eating?

Yes. Sildenafil can be taken with or without food, but a high-fat or large meal can delay how quickly it starts working.

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

Do not take more than one sildenafil dose in 24 hours. The 100 mg strength is already the maximum recommended dose for erectile dysfunction, so additional sildenafil should not be taken without medical direction.

Can I drink alcohol with sildenafil?

Avoid drinking large amounts. Excessive alcohol can interfere with erections and may worsen dizziness or light-headedness.

What should I do if an erection lasts too long?

Get urgent medical care if an erection lasts more than 4 hours. Prolonged erection, called priapism, can damage penile tissue if it is not treated promptly.

Can sildenafil be taken with nitroglycerin or other nitrate medicines?

No. Sildenafil must not be combined with nitrates or nitric-oxide donors because blood pressure can fall to a dangerous level.

Does Cheap Generic Med ship Spegra 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; prescription and personal-import requirements may also apply.

Will my Cheap Generic Med order have tracking?
