Brand Viagra: Oral Medication for Erectile Dysfunction

Viagra is an oral treatment for erectile dysfunction (also known as impotence) in men. The active ingredient is sildenafil citrate which is formulated as a blue film-coated tablet that is available in dosages of 25mg, 50mg and 100mg.

Drug Uses
Viagra may not be purchased without a doctor’s prescription. This drug is for use by men only. Women and children may not use Viagra. The active ingredient, sildenafil citrate, works by relaxing muscles, allowing an increased flow of blood to the penis. This should enable a man to achieve an erection during sexual stimulation, and to maintain it long enough for sexual intercourse. You can buy Brand Viagra 100mg online from a trustworthy online shop.

Dosage
The usual dose is 50mg to be taken approximately an hour prior to sexual stimulation. However, Viagra may be used between 4 – 0.5 hours before sexual stimulation. Depending on individual tolerance and effectiveness of Viagra, a doctor may need to increase the dosage to a maximum of 100g, or a minimum of 25mg. Viagra should not be used more than once a day. Always use Viagra as prescribed by a doctor. Do not increase or decrease the dose without a doctor’s permission.

Missed Dose
Because Viagra is used when required, this does not apply.

Precautions
Men who are at risk of heart attack may not be able to engage in sexual activity, and therefore cannot use Viagra. If you have a history of heart-related problems you will need to discuss the risks of using Viagra with your doctor.

Men who have suffered a stroke or serious arrhythmia (irregular heart beat) within the past six months should use Viagra with extreme caution.

Men with low blood pressure (resting 90/50), and men with high blood pressure (resting 170/110) should use Viagra with extreme caution.

Men who have suffered cardiac failure, heart disease or unstable angina should use Viagra with extreme caution.

Men who have retinitis pigmentosa (a genetic eye condition) should use Viagra with extreme caution.

Rare reports of prolonged erection after using Viagra have been reported. In the event of this occurring, a doctor should be contacted immediately as an erection lasting more than four hours can cause serious damage to the penis and may even result in permanent impotence.

Men using alpha-blockers should use Viagra with caution.

Before prescribing Viagra, your doctor will need to have a full knowledge of your medical history, and details about any other medications you are using.

Side-effects
Viagra has a good safety record with very few reports of side-effects. Some common side-effects may include vision problems (blurred vision or sensitivity to light), dizziness, rash, diarrhea, urinary tract infection, nasal congestion, stomach irritations, flushing, or headache. These are usually temporary and should disappear quickly. If any of these or other uncomfortable symptoms persist, contact your doctor.

Overdose
No cases of overdose with Viagra have been reported. However, excessive dosages will cause medical complications. If overdose is suspected, get medical assistance immediately.

Storage
Viagra should be kept in a cool, dry place away from sun and moisture.
