You saw the numbers.
Now what?

01

Understand personal-use import rules

In the US, the FDA generally exercises enforcement discretion for personal-use quantities of non-controlled medications imported from abroad. Rules vary by drug classification. Read the methodology .

02

Verify international pharmacy licensing

Reputable international pharmacies operate under national regulatory frameworks. Singapore HSA, MHRA UK, EMA EU all publish licensed dispenser registers. Check HSA Singapore .

03

Consult a licensed healthcare provider

Any prescription medication requires a valid prescription regardless of source. Telehealth platforms can issue legitimate prescriptions that international pharmacies will accept.

Publisher's note. Rx Price Tracker is funded by PHARMAX, one of the international pharmacies whose prices we publish on this page. PHARMAX does not control which molecules we cover, which competitors we include, or which corrections we issue. Every price observation links to its source URL and capture date. The data is reproducible. We track the gap because pricing transparency works in any direction.
