The United States is the most nuanced of the major markets when it comes to importing prescription medicine, and it is important to be accurate: the rules are stricter than many websites imply. Here is what US policy actually says.
Is it legal to import prescription medicine to the USA?
As a starting point, US law generally does not permit individuals to import prescription drugs for their own use. What exists is FDA enforcement discretion: the agency may choose not to act against a personal-use import in limited circumstances. This is discretion, not an entitlement — an FDA inspector can still detain a shipment that appears to meet every condition.
The conditions the FDA looks at
Where the FDA has exercised discretion for personal imports, it has generally looked for: the product being for a serious condition for which effective treatment may not be available in the US; the drug not presenting an unreasonable risk; no commercialisation to US residents; and a written affirmation that the product is for personal use. The quantity has generally been limited to about a 90-day supply.
Controlled substances: a hard limit
Controlled substances are treated far more strictly. The DEA applies a hard cap (commonly cited as 50 dosage units) at the border with no discretionary waiver. Controlled substances should not be imported by mail.
Customs & what to expect
Both the FDA and US Customs and Border Protection can inspect, detain, or refuse a shipment. Because clearance is never guaranteed, it is your responsibility to understand the current FDA position and the risk that a package may be held.
How OnlineMeds handles orders to the USA
However you order, our process is the same: a valid prescription is required and is reviewed by a licensed pharmacist before dispatch, we may ask for basic identity/address documentation, and we follow the local guidelines of your destination before any medicine is sent. Orders ship in discreet, tracked packaging. Full details are on our shipping & delivery page, and there is more general guidance in our guide to prescription regulations for global orders.
Because the FDA and US Customs can inspect or hold shipments, keeping a copy of your prescription with the order and staying within personal-supply limits makes clearance smoother. Used as prescribed by a licensed medical professional.
Frequently asked questions
Is it legal to import prescription medicine to the USA for personal use?
Generally, US law does not permit individuals to import prescription drugs for their own use. In practice the FDA exercises enforcement discretion and may allow a personal-use import in limited circumstances — but this is discretion, not a legal right, and shipments can still be detained.
What is the 90-day guideline?
Where the FDA does exercise discretion, it has generally allowed up to a 90-day supply for personal use, alongside conditions such as the drug being for a serious condition, no unreasonable risk, and a written statement that it is for personal use.
What about controlled substances?
Controlled substances are much stricter: the DEA applies a hard limit (commonly cited as 50 dosage units) at the border, with no discretionary waiver. Do not attempt to import controlled substances by mail.
Does the FDA guarantee my package will clear?
No. Enforcement discretion is not a guarantee — the FDA and Customs can detain or refuse a shipment even when it appears to meet the usual conditions. Confirm the current FDA position before ordering.
