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.

What to avoid

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). 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. If the insurance plan covers erectile dysfunction medications, generic sildenafil for ED treatment is probably covered, too. Keep in mind that while generic ED medications may be covered by insurance, brand-name sildenafil softgel capsule versions may not be covered. If sildenafil prices are difficult to manage, ask your healthcare provider about sildenafil alternatives.
