Viagra 100 mg

Viagra 100 mg is used to treat erectile dysfunction in adult men. It can be prescribed for men experiencing difficulty:

• Achieving an erection

• Producing an erection firm enough for penetration

• Maintaining an erection during sexual activity

• Responding physically despite sexual stimulation

• Managing ED associated with certain health conditions

Erectile dysfunction can be connected with reduced penile blood flow, diabetes, high blood pressure, high cholesterol, obesity, smoking, stress, anxiety or certain medicines.

Viagra improves the physical erectile response but does not address every underlying cause. Repeated erection problems should be medically evaluated, especially when they develop suddenly or occur alongside chest pain, reduced exercise tolerance or other cardiovascular symptoms.

When correctly selected and taken, Viagra 100 mg can provide the following benefits:

• Improves blood flow into the penis

• Helps produce a firmer erection

• Supports erection maintenance during sex

• Works only when sexual stimulation occurs

• Provides an as-needed treatment option

• Offers a flexible administration window

• Can improve confidence during sexual activity

• Contains a recognised sildenafil strength

The medicine supports the physical response to arousal without acting as an aphrodisiac or hormone. It should not cause an erection when sexual stimulation is absent.

Individual response can be affected by food, alcohol, timing, stimulation and the underlying cause of erectile dysfunction.

Sexual stimulation triggers the release of nitric oxide in the penis. Nitric oxide activates a substance known as cyclic guanosine monophosphate, or cGMP. This relaxes smooth muscle and widens the blood vessels supplying the erectile tissues.

An enzyme called phosphodiesterase type 5, or PDE5, breaks down cGMP. When cGMP is broken down too quickly, sufficient blood flow may not be maintained for a firm erection.

Sildenafil blocks PDE5 for a limited period. This allows cGMP to stay active longer and supports increased penile blood flow during sexual stimulation.

Viagra does not keep the penis permanently erect. After sexual activity, the normal chemical signals reduce and the erection should subside naturally.

Viagra 100 mg is taken as needed, approximately one hour before sexual activity. Sildenafil can be taken between 30 minutes and four hours before sex, depending on how the body responds.

The 100 mg tablet represents the maximum recommended single dose for erectile dysfunction. It is generally prescribed when a lower sildenafil strength has not provided a sufficient response and treatment has been well tolerated.

Swallow the prescribed tablet with water. It can be taken with or without food, although a large or high-fat meal can delay absorption and make the medicine take longer to work.

Do not take more than one dose within 24 hours. Do not take an additional tablet if the first dose does not work immediately. Using more than the prescribed amount increases the likelihood of headache, flushing, indigestion, dizziness, vision changes, low blood pressure and a prolonged erection.

Sexual stimulation is necessary for Viagra to work. Insufficient stimulation, excessive alcohol, a heavy meal or taking the tablet too close to sexual activity can reduce its effect.

People aged over 65 and those with severe kidney impairment, liver impairment or interacting medicines can require a lower sildenafil dose. Do not divide a tablet unless the supplied product is designed for splitting and the required dose has been confirmed.

Common Side Effects: Viagra 100 mg can cause headache, facial warmth or flushing, indigestion, nasal congestion, dizziness, nausea, back pain, muscle aches and a mild skin rash. Temporary vision effects can include blurred vision, greater sensitivity to light or difficulty distinguishing between blue and green. Some reactions can be more noticeable at the 100 mg strength. Speak to a healthcare professional if they persist or become difficult to manage.

Serious Side Effects: Seek urgent medical help for chest pain, fainting, severe dizziness, sudden vision loss, a sudden reduction in hearing, breathing difficulty, facial or throat swelling, or an erection lasting longer than four hours. A prolonged erection requires immediate treatment to prevent permanent tissue damage. If chest pain develops, do not take nitrate medicine and tell the emergency-care team when sildenafil was taken.

Viagra 100 mg should not be taken by people for whom sildenafil or sexual activity is medically unsuitable. Important exclusions include:

• 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 unstable cardiovascular 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 Viagra is intended for adult men with ED

Medical assessment is also important for men with Peyronie’s disease, sickle cell disease, multiple myeloma, leukaemia, bleeding disorders, active stomach ulcers or inherited retinal conditions.

Tell the healthcare professional about every prescription medicine, non-prescription product and supplement 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. Both medicines widen blood vessels, and using them together can cause a dangerous fall in blood pressure. Recreational nitrites create the same risk.

Alpha-blockers and antihypertensive medicines can increase dizziness or low blood pressure. Certain antifungal, antibiotic and antiviral medicines slow the removal of sildenafil from the body and can make the 100 mg strength unsuitable.

Do not take Viagra with another sildenafil product or combine it with tadalafil, vardenafil, avanafil or another ED treatment unless specifically instructed.

• Keep away from direct sunlight.

• Store out of reach of children and pets.

• Do not use damaged or discoloured tablets.

• Check the expiry date before taking the medicine.
