The generic version of Viagra, sildenafil citrate, is expensive without insurance, costing over $1,400 for 30 tablets. Sildenafil is covered by health insurance for pulmonary hypertension but may not be for erectile dysfunction, depending on the insurer. Using a SingleCare prescription discount card can significantly reduce the cost of sildenafil, with prices potentially as low as $16 for 30 tablets. Sildenafil is the generic version of Viagra, the “little blue pill” used to treat erectile dysfunction (ED). However, sildenafil is also approved by the Food and Drug Administration (FDA) to treat pulmonary arterial hypertension (high blood pressure in the lungs’ arteries). How much you pay for sildenafil depends on what you need it for, as different uses require different doses. People with pulmonary hypertension may have to take daily doses. In contrast, treating erectile dysfunction involves taking doses right before sexual activity, so prescriptions may be for only a few pills per month. Sildenafil is not only the generic version of Viagra, but it is also the active ingredient in Revatio, a brand-name drug that treats pulmonary arterial hypertension. Like Revatio, sildenafil can be administered as a tablet, oral suspension, or injection. The cost of Viagra and Revatio will be different, and usually higher, than generic sildenafil. There are no over-the-counter versions of Viagra.

As a treatment for pulmonary hypertension, sildenafil is usually covered by health insurance, Medicare drug plans, and Medicaid. Injections may not be covered or may require prior authorization before the insurance approves them. Copay costs are typically low, but other factors, such as coverage gaps, can influence the final out-of-pocket cost. As a treatment for erectile dysfunction, however, generic sildenafil may or may not be covered. Private or employer health insurance plans are more likely than Medicare or Medicaid to cover ED medication. The best advice for insured patients is to call the insurance company.

Keep in mind that while generic ED medications may be covered by insurance, brand-name versions may not be covered.

For erectile dysfunction, there are other PDE5 inhibitors (phosphodiesterase-5 inhibitors) that work similarly to sildenafil and include Cialis (tadalafil) and Levitra (vardenafil). For people with pulmonary hypertension, sildenafil tablets, oral solutions, and injections are among the least expensive prescription medications used to control the condition. Tadalafil is an alternative PDE5 inhibitor used for pulmonary hypertension and may be less expensive than sildenafil. Other lower-cost treatments, like calcium channel blockers, diuretics, and digoxin, may be options for some patients, but other pulmonary hypertension drugs are usually more expensive.
