Viagra is a prescription medication available for purchase online in Australia for $2-$4 per pill. War veterans may be able to access subsidized viagra through the Australian Pharmaceutical Benefits Scheme. Other users must purchase this product through private prescription. Viagra is used to treat impotence and erectile dysfunction and in men by increasing blood flow to the penis. It achieves this by relaxing the blood vessels. This allows blood to more easily into the penis when sexually stimulated, resulting in an erection.
Viagra was approved for use in Australia in 1998. Prior to 1998, there were no comparable treatments for erectile dysfunction in Australia. To date, it has remained one of the most popular treatments.
Viagra tablets are taken orally at least 30 minutes, and up to 4 hours, prior to sexual activity. The optimal time to take this medication is 1 hour before intercourse. Faster acting administrations include sublingual (under the tongue) and mouth spray preparations. Viagra taken orally may be effective in as little as 12 minutes, though the average onset is 27 minutes, and in some cases it may take up to 70 minutes. For erections to occur following administration, the user must still be sexually stimulated. Viagra is effective for up to 5 hours. In addition to erections being easier to achieve, the refractory period following orgasm during this time may also be reduced, which means that an erection may be reached more quickly following orgasm. Although Viagra is not a cure for erectile dysfunction, it can temporarily and effectively treat erectile dysfunction in 90% of cases.
Users should not exceed 100mg tablet per day of regular Viagra, or one 150mg tablet of extra strength Viagra (Viagra XL). Regular Viagra is available in 25mg, 50mg, and 100 mg tablets. 50mg is the usual recommended dose. Users should not mix Viagra with alcohol, or recreational drugs such as poppers which contain butyl or amyl nitrates.
Viagra side effects
Side effects which have been reported by at least 1% of users are coughing, dizziness (especially when rising from a sitting or lying position), dry mouth, flushing, heartburn, headache, sleepiness, and stuffy nose. Serious side effects are not common, but if you experience more serious side effects such as severe dizziness, low blood pressure, muscle aches, nosebleeds, sudden hearing loss, temporary memory loss, or changes in vision (such as blurred vision, light sensitivity, changes in colour perception, temporary or partial vision loss, or double vision), you should consult with a doctor as soon as possible. Stop the medication and seek immediate medical attention if you experience any of the following: painful erection, erection lasting longer than 4 hours, chest pains, irregular heartbeat, or shortness of breath before or after sex, seizures, allergic reaction, a severe skin rash, a rash accompanied by a fever, difficulty breathing, or any signs of stroke.
