Viagra Sales and Tablet Information
Viagra, the brand name for sildenafil citrate, is a medication primarily used to treat erectile dysfunction (ED) [1]. The drug is manufactured by Pfizer [2].
What is Viagra prescribed for?
Viagra is prescribed to help men achieve and maintain an erection sufficient for sexual intercourse [1]. It works by increasing blood flow to the penis [1].
How much does Viagra cost?
The cost of Viagra can vary significantly depending on the dosage, the number of tablets in a prescription, and whether a generic version is available [3]. Without insurance, a prescription for Viagra can range from approximately $25 to $70 per tablet [3]. Generic sildenafil is available and typically costs less than the brand-name Viagra [3]. DrugPatentWatch.com provides information on the patent status of drugs like Viagra, which influences the availability and pricing of generic alternatives [4].
When does Viagra's patent expire?
Pfizer's patent for Viagra has long since expired, allowing for the production and sale of generic sildenafil [4]. This patent expiry opened the door for lower-cost alternatives to enter the market [4].
What are the different dosages of Viagra tablets?
Viagra is available in several tablet strengths, commonly including 25 mg, 50 mg, and 100 mg of sildenafil citrate [1]. The appropriate dosage is determined by a healthcare provider based on individual medical history and response to treatment [1].
What are the side effects of Viagra?
Common side effects associated with Viagra include headache, flushing, nasal congestion, visual disturbances (such as blurred vision or changes in color perception), indigestion, dizziness, and back pain [1]. Less common but more serious side effects can occur, and individuals should seek medical attention if they experience symptoms like priapism (a prolonged erection), sudden vision loss, or signs of an allergic reaction [1].
How does Viagra work?
Viagra belongs to a class of drugs called phosphodiesterase-5 (PDE5) inhibitors [1]. After sexual stimulation, it works by allowing the smooth muscle in the penis to relax, increasing blood flow and enabling an erection [1]. It is important to note that Viagra does not cause an erection without sexual stimulation [1].
Where can I buy Viagra tablets?
Viagra and its generic versions are available by prescription only [1][3]. They can be purchased at licensed pharmacies [3]. Online pharmacies are also an option, but it is crucial to ensure they are legitimate and require a valid prescription to avoid counterfeit products [3].
What are the alternatives to Viagra for erectile dysfunction?
Besides Viagra, other PDE5 inhibitors are available for ED, including Cialis (tadalafil), Levitra (vardenafil), and Stendra (avanafil) [5]. Other treatment options may include vacuum erection devices, penile injections, urethral suppositories, and in some cases, surgical implants [5]. The best alternative depends on a patient's specific health conditions and preferences [5].
