The bottom line: Americans pay more for prescription drugs than any other country — on average 2.56 times more than in 32 OECD nations. For some medications, the markup is 10x or higher. The same Novo Nordisk insulin, the same Pfizer statin, the same AstraZeneca inhaler costs a fraction of the US price in Colombia, Canada, the UK, and most of the developed world. Pharmacy tourism — purchasing medications legally abroad — is a growing phenomenon for Americans who pay out-of-pocket or face high insurance copays.

Prices represent typical pharmacy retail or cash-pay costs. US prices are without insurance or with high-deductible plans where patient pays full cost until deductible is met. Colombia prices reflect pharmacy (droguéria) retail pricing. Many medications available OTC in Colombia require a prescription in the US.
Why American Drug Prices Are the Highest in the World
The US is the only major developed country that does not regulate or negotiate prescription drug prices at the national level. While the Inflation Reduction Act (2022) authorized Medicare to negotiate prices for a limited number of drugs, the vast majority of medications remain priced at whatever the market will bear.
Other countries achieve lower prices through different mechanisms. Canada uses the Patented Medicine Prices Review Board (PMPRB) to cap prices based on international reference pricing. The UK's NHS negotiates directly with manufacturers through NICE (National Institute for Health and Care Excellence) cost-effectiveness assessments. Colombia regulates pharmaceutical prices through INVIMA (Instituto Nacional de Vigilancia de Medicamentos y Alimentos) and maintains a controlled pricing system for essential medications.
The result is a global pricing structure where the same manufacturer charges different prices in different markets — and the US pays the highest price by a wide margin. Americans are, in effect, subsidizing pharmaceutical company profits and global R&D through higher prices, while the rest of the world benefits from the same innovations at regulated costs.
Insulin is the most cited example of the American drug pricing crisis, and for good reason. A vial of Lantus (insulin glargine) that costs $275–$350 in the US sells for $20–$35 in Colombia. The same manufacturer (Sanofi), the same factory, the same molecule, the same biological activity. The only variable is the pricing structure of the country in which it's sold. For the estimated 8.4 million Americans who use insulin, the annual cost difference between US and Colombian pricing can exceed $3,000–$4,000 per year.
Pharmacy Tourism: How It Works
Pharmacy tourism — traveling abroad to purchase prescription medications at lower cost — is a growing practice among Americans, particularly those who are uninsured, underinsured, or taking expensive specialty medications. The practice operates in a legal gray area: the FDA technically prohibits importing prescription drugs for personal use, but the agency has a longstanding policy of generally not enforcing this prohibition for personal-use quantities (typically a 90-day supply) purchased from legitimate pharmacies.
In Colombia, many medications that require a prescription in the US are available over the counter at neighborhood pharmacies (droguérias). Common examples include antibiotics, blood pressure medications, cholesterol medications, and some anti-anxiety medications. For medications that do require a prescription in Colombia, a local physician consultation (typically $30–$80) can provide the necessary authorization.
Practical Considerations
Medical tourists and expats in Colombia should purchase medications from established pharmacy chains (Droguéria La Rebaja, Farmatodo, Locatel, Cruz Verde) rather than informal vendors. Verify that packaging is intact, expiration dates are current, and the medication name matches what you take at home (brand names may differ between countries). Bring your US prescription or a list of medications with generic names to ensure accuracy.
The Bigger Picture
Prescription drug pricing is one of the starkest illustrations of the fundamental question driving medical tourism: why do Americans pay so much more for the same healthcare products and services? The answer — structural pricing inefficiency, lack of negotiation power, and regulatory capture — applies not just to medications but to procedures, hospital stays, and virtually every dimension of healthcare spending. Medical tourism and pharmacy tourism are individual responses to a systemic problem.
