Typical retail ranges, not quotes. What you are charged depends on the pharmacy and on how the claim is processed — which is exactly why it is worth asking.

Where the money goes

Lisinopril is one of the cheapest drugs in America — often $4 for a month on a supermarket or big-box generic list. If you are being asked for much more than that, the problem is the pharmacy or how the claim was processed, not the drug.
Switch the toggle above to 90 days. Three months rarely costs three times one month, and on a drug this cheap that is the biggest lever you have.
Compare the cash-with-a-card price against your copay. On drugs this cheap the card frequently beats insurance.

What else there is

Not recommendations. The tradeoff matters more than the name, and it is the part a prescriber will want to talk about.

LosartanDifferent class

An ARB. The usual reason to move is the dry cough about one in ten people get on an ACE inhibitor — not cost, since both are inexpensive generics.

Enalapril, ramipril, benazeprilSame class

Same class, same mechanism, similar price. Switching within the class rarely saves money and rarely changes side effects.

Worth asking

Is a 90-day prescription reasonable for me?
If I am getting the cough, would an ARB be a sensible swap?

Before you change anything. Do not stop or change a blood pressure medicine on your own. Stopping abruptly can raise your pressure sharply.
