Viagra 50 mg

Viagra 50 mg is used for the treatment of erectile dysfunction in adult men. It can be prescribed when a man experiences difficulty:

• Achieving an erection

• Maintaining an erection during sexual activity

• Producing an erection firm enough for penetration

• Responding physically despite sexual stimulation

• Managing ED associated with certain health conditions

Erectile dysfunction can develop for several reasons, including restricted blood flow, diabetes, high blood pressure, high cholesterol, smoking, stress, anxiety or the use of particular medicines.

Viagra 50 mg supports the erectile response but does not treat the underlying cause of every case. A medical review can help identify whether lifestyle factors, another medicine or an untreated health condition is contributing to the problem.

When taken correctly, Viagra 50 mg provides several treatment benefits:

• Helps achieve a firmer erection

• Supports erection maintenance during sex

• Improves penile blood flow

• Works only with sexual stimulation

• Offers a flexible treatment window

• Can improve confidence in sexual performance

• Uses a recognised sildenafil strength

• Can be taken with or without food

The medicine supports the physical response to sexual stimulation without acting as a hormone or aphrodisiac. It does not create unwanted sexual arousal and does not cause a permanent erection when used correctly.

Its effectiveness can be reduced by a heavy meal, excessive alcohol, insufficient sexual stimulation or taking the tablet at the wrong time.

An erection begins when sexual stimulation causes the release of nitric oxide in the penis. This activates a substance called cyclic guanosine monophosphate, commonly shortened to cGMP. The increased cGMP relaxes smooth muscle and allows more blood to enter the erectile tissues.

An enzyme called phosphodiesterase type 5, or PDE5, breaks down cGMP. In men with erectile dysfunction, this can make it difficult to achieve or maintain adequate penile blood flow.

Sildenafil temporarily blocks PDE5. This allows cGMP to remain active for longer, helping the penile blood vessels relax and fill with blood during sexual stimulation.

Viagra does not cause an erection without arousal. After sexual activity, blood flow decreases naturally and the erection should subside normally.

For most adult men, the recognised dose is one Viagra 50 mg tablet taken as needed, approximately one hour before sexual activity. It can be taken between 30 minutes and four hours before sex, depending on individual response.

Swallow the tablet with water, with or without food. A high-fat or heavy meal can slow absorption and delay the time it takes to work. For a more predictable response, avoid taking it immediately after a large meal.

Do not take more than one dose within 24 hours. Taking another tablet because the first dose did not work immediately can increase the risk of headache, low blood pressure, vision changes and a prolonged erection.

The dose can be reduced to 25 mg or increased to 100 mg based on response, tolerability, health conditions and interacting medicines. Older adults and people with severe kidney impairment, liver impairment or certain medicine interactions can require a lower dose.

Viagra requires sexual stimulation to work. Anxiety, excessive alcohol, inadequate stimulation or incorrect timing can affect the response. Do not increase the dose without medical guidance because one unsuccessful attempt does not necessarily mean the medicine is ineffective.

Common Side Effects: Viagra 50 mg can cause headache, facial warmth or flushing, indigestion, nasal congestion, dizziness, nausea, back pain, muscle aches or a mild skin rash. Temporary visual effects such as blurred vision, increased sensitivity to light or a blue-green colour tinge can also occur. These reactions usually settle as sildenafil leaves the body, but continuing or troublesome symptoms should be discussed with a healthcare professional.

Serious Side Effects: Obtain urgent medical help for chest pain, fainting, severe dizziness, sudden loss of vision, a sudden reduction in hearing, facial or throat swelling, difficulty breathing or an erection lasting longer than four hours. A prolonged erection can damage penile tissue if it is not treated promptly. Do not use nitrate medicine for chest pain after taking Viagra; inform the emergency-care team when sildenafil was taken.

Viagra 50 mg is not suitable for everyone. It should be avoided or used only after specialist assessment by:

• People taking nitrate medicines

• People using recreational nitrites or “poppers”

• People taking riociguat

• Anyone allergic to sildenafil

• People advised to avoid sexual activity

• People with severe or unstable heart disease

• People with very low blood pressure

• People with a recent heart attack or stroke

• People with serious liver impairment

• People with previous sildenafil-related vision loss

• Children and adolescents

• Women, as this product is intended for adult men with ED

Extra care is required in people with Peyronie’s disease, sickle cell disease, leukaemia, multiple myeloma, active stomach ulcers, bleeding disorders or inherited retinal conditions.

Tell the healthcare professional about all medicines, supplements and recreational substances being used. Important interactions include:

• Nitrate medicines

• Riociguat

• Alpha-blockers

• Blood-pressure medicines

• Other PDE5 inhibitors

• Ritonavir

• Saquinavir

• Ketoconazole

• Itraconazole

• Erythromycin

• Clarithromycin

• Grapefruit products

Nitrates such as nitroglycerin and isosorbide must not be combined with Viagra because the combination can cause a dangerous fall in blood pressure. Recreational products containing amyl nitrite or butyl nitrite create the same risk.

Alpha-blockers and antihypertensive medicines can add to sildenafil’s blood-pressure-lowering effect. Strong CYP3A4 inhibitors, including certain antifungal, antibiotic and antiviral medicines, can increase sildenafil levels and require a lower dose.

Do not combine Viagra with sildenafil-containing pulmonary hypertension medicines or another ED treatment such as tadalafil, vardenafil or avanafil unless specifically instructed.
