Viagra is a phosphodiesterase-5 inhibitor tablet containing sildenafil citrate that is used for the treatment of erectile dysfunction. It is manufactured by Pfizer and comes in dosage strengths of 25 mg, 50 mg, and 100 mg. When alpha blockers are also used, Viagra should be started at the 25 mg dose, as Viagra can exacerbate the hypotensive effects of alpha blockers, in addition to nitrates and antihypertensives. The 25 mg starting dose of Viagra should also be considered when using erythromycin or strong CYP3A4 inhibitors, such as ketoconazole, itraconazole, or saquinavir. The most common adverse reactions to Viagra include headache, flushing, dyspepsia, abnormal vision, nasal congestion, back pain, myalgia, nausea, dizziness, and rash, according to the drug’s prescribing information.
Viagra for sale in Australia online – no prescription needed
In terms of how to acquire Viagra in Australia, a number of illegal online pharmacies sell what they claim to be generic Viagra in Australia without a prescription. One such website at the address https://edonlinestore.net/buy-viagra-online-au-en.html sells a variety of Viagra forms, including Brand Viagra, Generic Viagra, Viagra Caps, Viagra Gold, Viagra Jelly, Viagra Soft, Viagra Super Active, Viagra Professional, Viagra With Dapoxetine, Red Viagra, and even Female Viagra. It also claims to offer dosages of 120 mg, 130 mg, 150 mg, and 200 mg—which are all notably higher than the highest-approved dosage by the US Food and Drug Administration.
The price per unit (or pill) decreases as the quantity ordered increases. For instance, a package of 360 100 mg Generic Viagra pills (plus a free erectile dysfunction trial pack) has a listed price of AU$1.10 per pill, while a package of 20 100 mg Generic Viagra pills (plus 4 free tablets) has a listed price of AU$3.49. As a bonus, the online pharmacy offers Free Airmail Shipping for the larger offered quantities of Viagra in all dosage forms and strengths. It is important to point out that the consumer cost for Viagra per 50 mg pill in the United States was between USD$25.17 and USD$37.88 in 2015. This means that consumers in Australia who obtain Viagra through online pharmacies are reaping huge discounts on the drug.
However, buying erectile dysfunction drugs such as Viagra online without a prescription comes with great risk. For instance, one study by Viagra manufacturer Pfizer uncovered that approximately 80% of websites claiming to sell Viagra online were actually selling counterfeits. Even when the erectile dysfunction drug sold online does contain the right ingredient (such as sildenafil in Viagra), it could be the wrong dosage strength, since only 10% of the 100 mg Viagra pills that were purchased online and tested by the US Food and Drug Administration came anywhere close to that dosage strength.
Even legitimate Viagra should not be used if sexual activity is advised against due to cardiovascular problems. If an erection lasts more than 4 hours, seek emergency treatment. If too much Viagra is taken, immediately call a doctor or Poisons Information Center. (The phone number for one in Australia is 13 11 26; in New Zealand, it’s 0800 POISON or 0800 764 766.)
