Below are answers to some frequently asked questions about sildenafil and cost.
Do the different strengths of sildenafil cost the same?
No, the different strengths of sildenafil typically vary in cost. Each form of sildenafil comes in different strengths. And both the strength and form of sildenafil you use can affect the drug’s cost.
The chart below shows the available forms and strengths of sildenafil.
| Form | Strength |
| powder that’s mixed with water to form a liquid suspension (a type of liquid mixture) taken by mouth | 10 milligrams (mg) per milliliter (mL) |
| liquid solution given as an intravenous injection* | 10 mg per 12.5 mL |
| tablets taken by mouth | 20 mg, 25 mg, 50 mg, 100 mg |
* This form is given by a healthcare professional during a hospital stay.
Your doctor may prescribe a strength of sildenafil that isn’t available from the drug manufacturer. For example, they might prescribe you 60 mg of sildenafil. In this case, you may take three of the 20 mg tablets to form 60 mg. It’s important to note that the number of tablets you’re prescribed can also affect the price you pay for sildenafil.
If you have other questions about how the different strengths of sildenafil vary in cost, talk with your doctor, pharmacist, or insurance provider.
