Generic Drugs - Are they really the same?

What is a generic drug?

When a brand-name drug's patent runs out, other companies can make copies. Those copies are generic drugs, and the FDA has to approve everyone.

• A generic has the same active ingredient, strength and form as the brand, and it should work the same way.

It has to meet the same quality and safety standards as the brand, or the FDA won't approve it.

• Many people hear "generic" and think "cheap and inferior." For the most part, that isn't true.

• About 9 in 10 prescriptions in the U.S. are filled with generics, yet they make up only about 12% of what we spend on prescription drugs.

What is the difference between generic and brand-name drugs?

 Mostly the name, the look and the price.

• The name. Every drug has a generic name for its active ingredient. Crestor is the brand name for rosuvastatin. A generic is usually sold under the ingredient's name.

• The price. A generic generally costs a lot less than the brand. The makers don't have to repeat the research and testing the brand company paid for.

• The look. A generic may be a different size, color or shape, with different markings. Trademark law won't let a generic look just like the brand.

• The inactive ingredients. Colors, flavorings and fillers can differ. They rarely matter, but they can affect some people, such as those with allergies.

There can be more than one generic for the same brand. If your pharmacy switches makers, your pill may change color. Ask your pharmacist to explain the change.

Not every brand-name drug has a generic. Biologic drugs, like many arthritis medicines, have biosimilars instead. See our Biological Drugs page.

Who makes generics, and are they safe?

The FDA says approved generics are safe. Where they come from is the part that worries people.

• India makes about half of the generic prescriptions filled in the U.S.

• China supplies many of the key starting materials and active ingredients, even for drugs made in India.

• Only a small share of the factories that make active ingredients are in the United States.

The FDA does inspect foreign factories. But they are harder to inspect than U.S. ones, and members of Congress have called for more inspections, including surprise ones.

Some overseas plants have been cited for falsified test data and contaminated ingredients. The number of incidents is small next to the number of drugs made, but many people are still concerned.

Shortages and tariffs

Generics sell for very little, and some are hard to make at a profit. Industry groups say that contributes to shortages. Tariffs on imported drugs could add to the problem.

♦ Generics were left out of the 2026 tariffs on brand-name drugs, but a phased tariff on generics has been reported for 2028. Plans can change, so keep an eye on the news.

Generics and your insurance

Most plans charge less for generics than for brand-name drugs. In employer plans with three or more tiers, the lowest tier, which usually holds generics, averaged a $12 copay in 2026.

Preferred generic vs. non-preferred generic

Many plans now split generics into two levels, much like they do with brand-name drugs. The copay difference can be $10, $20 or even more. It is not uncommon to pick up a generic and be hit with sticker shock.

• There have already been a number of lawsuits filed against insurance companies for classifying some long standing generics for the treatment of H.I.V. as non-preferred thereby throwing them into a much higher costing tier for the patient.

• Many generics have risen in price due to demand and supply problems. This has put a squeeze on insurance companies’ profits.

To shift the cost more toward the patient, most insurance company are now classifying a much smaller number of generics at the lowest cost tier of preferred generic.

• Just because it's a generic doesn't mean it's covered. Your plan keeps a list of covered drugs, called a formulary, and your drug has to be on it.

• Some plans won't cover a brand-name drug when a generic is available.

• Others make you try a cheaper drug first. That's called step therapy.

Cash can beat your copay

Some generics cost less at the counter without insurance, using a discount card or the pharmacy's own low-price list. Ask your pharmacist for the cash price. Then ask your plan whether money you spend outside your insurance counts toward your deductible.

Generic equivalent vs. generic alternative

These two terms get mixed up, and the difference matters.

• A generic equivalent is a true copy. It has the same active ingredient, strength and form as the brand, and the FDA rates it as interchangeable with it. Depending on your state, your pharmacist can usually swap it in without calling your doctor.

• A generic alternative is a different drug. It treats the same condition and may be in the same drug family, but the active ingredient is not the same. It may or may not work as well for you. Your pharmacist can't swap it in on their own. Your doctor has to prescribe it.

Your plan may push an alternative because it costs less or has a longer track record. Your doctor is the best person to ask whether it's a good option for you.

Is there a generic for my brand-name drug?

Start by asking your doctor. Next, ask your pharmacist. They can usually tell you in a minute.

If you want to look it up yourself, the FDA keeps a searchable list called the Orange Book. It isn't easy for the average person to understand, so don't be discouraged.

1. Search by the brand name to find the active ingredient.

2. Search again using the active ingredient.

3. If companies other than the brand's maker are listed, those are the generic makers.

A newly approved generic can take a while to show up. If you find nothing, ask your pharmacist.

When to talk with your doctor first

For most drugs, switching to a generic is fine. For a few, the safe dose range is very narrow, and a small difference can matter. If your drug is one of those, ask your doctor before you switch. Do the same if you notice new side effects after a switch.
