3. How to save on generic Viagra
Archived from the original on 22 December 2020. ^ a b "Pfizer Settles Viagra® Patent Litigation With Teva". "Lockout Supplements Issues Voluntary Nationwide Recall of Boner Bears Chocolate Syrup Due to Undeclared Sildenafil". Archived from the original on 19 November 2016. "Counterfeit Viagra, Cialis, Levitra: The Ultimate Guide". Viagra is so popular that its name has become synonymous with ED treatment — just like Ziploc has with plastic bags. It’s been a wild success since it entered the market in 1998. But in 2013, Teva Pharmaceuticals made a generic form of sildenafil to compete with Viagra. After a long court battle and approval by the Food and Drug Administration (FDA), Pfizer paid Teva to not release their generic form until 2017. So, here’s what you should know about it — how it works, how it compares to Viagra, and what precautions you should take.
| Form | Available Strengths | Description | Notes |
|---|---|---|---|
| Tablets | 25 mg, 50 mg, 100 mg | Standard oral tablets | Most common dosage |
| Sublingual Tabs | 25 mg | Dissolve under tongue | Rapid absorption |
| Liquid Suspension | 10 mg/5 mL | For easy dosing, especially in children | Requires precise measurement |
This means that it helps block the PDE5 enzyme that affects certain muscles in your penis and heart.

What are the most common side effects of sildenafil?
"Oral sildenafil in the treatment of erectile dysfunction. Archived from the original on 14 January 2012. "Onset and duration of action of sildenafil for the treatment of erectile dysfunction". ^ "Scientist who developed Viagra receives knighthood in New Year's Honours". Archived from the original on 14 January 2023. PDE5 can restrict blood flow to blood vessels in the spongy penis tissue called corpus cavernosa. This tissue helps your penis get erect when you’re aroused. During arousal, it becomes filled with blood. Teva sildenafil and other similar medications help stop PDE5 from restricting blood flow into these blood vessels. By doing this, it helps your penis get enough blood to maintain an erection. PAH can cause smooth muscle in your lungs to become inflamed and restrict blood flow in certain lung arteries. PDE5 inhibitors like Teva sildenafil help dilate these arteries and reduce your blood pressure. You can get Teva sildenafil with a prescription from your doctor. It comes in the following tablet sizes: It also comes as an oral suspension (liquid form) or an injection given by your doctor. Teva sildenafil is prescribed to people who have difficulties having an erection or staying erect throughout a sexual encounter. This medication is very similar to Viagra and works to help with erectile dysfunction by inhibiting PDE5, an enzyme that can cause the penis to not become erect or lose an erection prematurely.

Since Teva sildenafil is available as a generic drug, one of the major benefits over Viagra is its lower cost. This means that a person experiencing ED can receive many of the benefits of taking Viagra at a reduced cost. This is especially beneficial if prescription Viagra is outside of a person’s budget. While a majority of Teva sildenafil users take the medication to treat ED, it is also approved to treat pulmonary arterial hypertension (PAH) as well. Your doctor may choose to prescribe it for treating PAH, even when symptoms of ED are not present. Additionally, research shows Teva sildenafil may be effective in Teva sildenafil only works properly if you take it about an hour before you have sex.
