The government website TrumpRx.gov gives Americans a new option for getting their medications. But it also adds to the complexity of a system that can make it extraordinarily difficult for people to compare prices and figure out where to find the least expensive drug.

Introduced on Thursday, the website does not sell prescription drugs. Instead, it allows people to look up their drugs and then navigate to buy them elsewhere, either from a major drug company or a pharmacy. The 43 drugs listed on the site have prices ranging from $3 to over $5,500.

TrumpRx does include warnings that the site may not be the best option to save money on prescriptions. Each product page advises: “If you have insurance, check your co-pay first — it may be even lower.”

Here’s information about the site and whether you could benefit from using it.

Can I use my insurance on TrumpRx?

For now, the website says its prices are for people paying with their own money, rather than going through insurance. But TrumpRx directs people to an Eli Lilly site where they can use their insurance to get Zepbound, the popular weight-loss drug.

Who will benefit from TrumpRx?

The site’s prices are aimed at people who lack insurance coverage for their medication, or would face higher out-of-pocket costs if they used their coverage.

That situation is most common for obesity and fertility drugs, which are often not covered by insurance. People without any health insurance could also benefit, though in many cases manufacturers offer drugs to this group for free or at steeply reduced prices.
