Using generic drugs
National medical care costs continue to rise year after year. “Generic drugs” are one solution expected to help hold down medical care costs. Switching from brand-name drugs to generic drugs is also easier on household budgets and should contribute significantly to cutting medical care costs. Be sure to read all the information provided below to ensure a proper understanding of the benefits of generic drugs, then use them to save on medical care costs.
What are generic drugs?
As you may have gathered from television ads, generic drug are drugs introduced after the period of exclusivity of brand-name drugs (i.e., the term of the drug patent, in principle 20-25 years) has expired. Featuring the same active ingredients as brand-name drugs, they are available at lower cost due to lower development costs.
Benefits of choosing generic drugs
Switching from brand-name drugs to generic drugs can lower what you pay at the pharmacy. While this may not amount to much for medicines taken over a short period of time, like cold medicines, it can cut drug costs significantly for people who require medicines over extended periods to treat chronic conditions like dyslipidemia, high blood pressure, or diabetes.

How to switch to generic drugs
Start by asking your doctor
Ask your doctor if you are currently undergoing treatment and have not yet switched to generic drugs. Whatever reluctance you might feel in asking such a question, simply asking “Can I use generic drugs?” can cut your drug costs dramatically. With prompting from the Ministry of Health, Labour and Welfare of Japan, growing numbers of medical care institutions are taking active steps to encourage the use of generic drugs. Don't be afraid to ask.
Check “the No substitutions” space on your prescription
Current prescriptions indicate whether or not it is possible to switch to generic drugs for each medicine. In a case of generic prescribing* using a generic name for a drug instead of a trade name, you are free to choose a generic drug at the pharmacy.
- *Generic prescribing refers to writing prescriptions on which the doctor specifies active ingredients instead of trade names for drugs. Sometimes a generic drug will be denoted by the word generic preceding the drug name.
You can also try switching to generics temporarily
If you are worried about switching suddenly to generic drugs, you can split the number of days of the prescription. For example, for a four-week prescription, you can have the prescription filled for just the first week, then have the prescription for the remaining three weeks filled if there are no problems with the medicine. (This is called split dispensing.) When you use this split prescription system to try switching to generic drugs, the split dispensing fee will be added for only the second time the split prescription is dispensed. Ask your pharmacist for more information.
Your copayment may be higher if you request a brand-name drug for which generic drugs are available
From October 2024, for certain drugs, a surcharge equal to one-fourth of the difference in drug prices will apply if you request a prescription for a (long-listed) brand-name drug for which generic drugs are available.
We encourage you to take this occasion to start making active use of generic drugs.
Surcharge applies to either of the following brand-name drugs:
- Brand-name drugs for which equivalent generics were first listed on drug price standards five or more years ago (excluding those for which the rate of generics substitution is fewer than 1%).
- Brand-name drugs for which equivalent generics were first listed on drug price standards less than five years ago but for which the rate of generics substitution is 50% or more.
- * This excludes a case in which your doctor or dentist identifies a medical need to prescribe or administer brand-name drugs.
Try using “a generic drug request card”
When you visit a medical care institution or get a prescription filled at a pharmacy, you can present this card to make it easier to indicate your preference for generic drugs.
