Don’t take Viagra more than once per day. If Viagra isn’t working for you, your doctor may increase your dose of the drug. Your doctor may prescribe a different dosage of Viagra for you depending on several factors. These factors may include having liver or kidney problems, taking certain other medications, and being 65 years or older.

Generic forms of both drugs are available. Brand-name medications usually cost more than generics. The actual price you’ll pay for either drug depends on your insurance plan, your location, your prescribed dosage, and the pharmacy you use. In addition to being available as the brand-name drug Viagra, it’s available as a generic drug. Here we look at how Viagra and sildenafil are alike and different. Viagra, which contains the active drug sildenafil, is a brand-name drug.

• Sildenafil generic is a popular choice for ED treatment worldwide.
• It provides a less expensive yet effective solution for erectile issues.
• The drug's popularity has increased due to patent expiration of brand-name Viagra.
• Always check for proper licensing and approval before purchasing.
• Consulting a healthcare provider ensures the correct dosage and safety.
• Many online sources offer genuine sildenafil generics with verified credentials.

But sildenafil is also available as a generic medication. A generic medication is an exact copy of the active drug in a brand-name medication. The Food and Drug Administration (FDA) considers generics to be just as safe and effective as the original drug. Generics tend to cost less than brand-name drugs. Viagra is approved to treat ED in males ages 18 years and older. It comes as tablets that you take by mouth.

For example, sildenafil 25-mg, 50-mg, and 100-mg tablets are approved for this use. In addition, sildenafil also comes as 20-mg tablets, an oral liquid suspension, and a solution given by injection. These forms of sildenafil are generic versions of a brand-name drug called Revatio. But unlike Viagra, they’re not used to treat ED. Revatio and these forms of sildenafil are used to treat pulmonary arterial hypertension (PAH). With PAH, you have high blood pressure in the artery between your heart and lungs. This means that generic sildenafil is just as effective in treating ED as Viagra is when it’s taken at the same doses as Viagra. It also means that sildenafil and Viagra can cause the same side effects. For information on the possible side effects of Viagra, see the “Viagra side effects” section.

• Sildenafil generic is a cheaper alternative to Viagra for erectile dysfunction treatment.
• Generic sildenafil contains the same active ingredient as branded versions.
• It is approved by regulatory authorities like the FDA for safety and efficacy.

You should also avoid products you can buy online without a prescription that claim either to be generic forms of Viagra or to contain sildenafil. (Sildenafil is the active drug in Viagra.) If these drugs are available without a prescription, that means that they haven’t been tested or approved by the FDA.

However, the active drug in Levitra is available as a generic medication called vardenafil. The generic form has the same use, dosage, safety, and effectiveness as the brand-name drug. The information about Levitra in this article also applies to vardenafil unless otherwise noted. Viagra contains the drug sildenafil, while Levitra contains the drug vardenafil. Both Viagra and Levitra belong to a group of drugs called phosphodiesterase type 5 (PDE5) inhibitors.
