Generic drugs provide the same clinical benefits — but they often save you money
Generic drugs can often help save you money by providing less expensive options for the medications you’re already taking. Generic drugs must meet the same high standards as brand-name drugs to receive Food and Drug Administration (FDA) approval , so they’re also safe and effective.
Generic drugs are made by manufacturers to provide the same clinical benefit to you as their brand-name counterparts. In other words, you can take a generic medicine as a clinically equal substitute for its brand-name equivalent.1
Both generic drugs and their brand-name equivalents:
- Contain the same active ingredients
- Work the same way
- Are taken the same way
- Have the same associated risks and benefits
- Meet the same quality and manufacturing standards
- Are clinically effective
- Have safe inactive ingredients2
As an example, lisinopril is the generic drug equivalent of the brand-name drugs Prinivil and Zestril. All three drugs are used to treat high blood pressure, treat heart failure and improve survival after a heart attack.3 All three drugs have the same active ingredients. They are available in the same strengths, prescribed in the same quantity and are administered the same way.

The key differences between generic drugs and brand-name drugs
You’ll find the biggest difference between generic drugs and brand-name drugs is their price: Some generic drugs are up to 85 percent less expensive than their brand-name equivalents.1 They’re backed by FDA quality control standards and are required to contain the same active ingredients as the brand-name medicines they’re modeled after.
The biggest difference between generic and brand-name drugs is the price. Generic drugs might cost you significantly less than your equivalent brand-name medicines.1 Because of this, generic drugs are a popular option for many patients. Currently, they make up about 90 percent of prescriptions filled in the United States.4
Aside from cost, there are some additional differences between generic and brand-name medicines you want to be aware of.
Compared to their brand-name counterparts, generic drugs:
Generic drugs tend to cost you less than their brand-name counterparts because the companies that apply to manufacture generic drugs do not have to repeat the animal and clinical (human) studies that were required of the brand-name medicines to demonstrate their safety and effectiveness.1 Because these tests can be very expensive, the reduction in up-front research cost for generic drugs means that they are able to be sold to you at a substantial discount.

Yes. Generic drugs provide the same clinical benefit as their brand-name equivalent. That’s because they’re required to contain the same active ingredients as the brand-name medicines they’re modeled after, and they must be manufactured to work the same way.1 The FDA Generic Drugs Program conducts a rigorous review of generic medicines to ensure that they all meet these standards.1
Yes. Generic drugs are safe for you to use. All generic medicines must provide the same clinical benefit as their equivalent brand-name medicines. They must also meet the same high standards of quality and manufacturing as their brand-name equivalents.1 While generic drugs have similar safety profiles to their branded counterparts, it’s important that you speak with your doctor prior to changing any of your prescriptions.
Yes. Generic drugs are covered under some insurance plans. In fact, for insurance plans that provide different copayment options, the use of generic drugs over their name-brand equivalents is sometimes encouraged. For example, the copay for a generic drug may be less than that of its name-brand counterpart.6 It’s important to check with your insurance company to know which drugs they cover and their associated copays.
Common conditions treated with generic drugs
Working with your provider and pharmacist can help you better understand the prescription options you may have and how to make the most informed decisions about your health. If you’re currently taking any of these brand-name equivalents, you may want to ask your provider if a generic equivalent may be right for you.
Common generic drugs prescribed for mental health
Many brand-name drugs (such as antidepressants, antipsychotics and mood stabilizers)prescribed to help treat mental health conditions have a generic drug alternative.* Here are a few common generic drugs* that you might have already heard of.
Duloxetine is called a serotonin-norepinephrine reuptake inhibitor (SNRI) and works by helping restore the balance of serotonin and norepinephrine in the brain.
Duloxetine is used to treat depression and anxiety. It’s also sometimes used to help relieve specific kinds of nerve pain in patients with diabetes or to help relieve ongoing pain due to arthritis, chronic back pain or fibromyalgia.
This medication may improve your appetite, energy level, mood and sleep.
It may decrease nervousness and pain due to certain medical conditions. Read more about duloxetine.
Escitalopram belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs). It works by helping restore the balance of serotonin, a certain natural substance in the brain.
Escitalopram is used to treat depression and anxiety. Patients who take this drug may experience an improved energy level, feelings of well-being and decreased nervousness. Read more about escitalopram.
Like escitalopram, fluoxetine is an SSRI. It works by helping restore the balance of serotonin, a certain natural substance in the brain.
Fluoxetine is used to treat depression, a certain eating disorder (bulimia), obsessive compulsive disorder, panic attacks and a severe form of premenstrual syndrome (premenstrual dysphoric disorder).
This medication may improve your appetite, energy level, mood and sleep and may help restore your interest in daily living.

Sertraline is used to treat depression, obsessive compulsive disorder, panic attacks, post-traumatic stress disorder, social anxiety disorder (social phobia) and a severe form of premenstrual syndrome (premenstrual dysphoric disorder).

Common generic drugs prescribed for heart health
There are several common generic drug options* for medications used to help treat heart conditions and help improve heart health. Here’s a list of some of the more commonly prescribed generic drugs.
Apixaban is an anticoagulant that works by blocking certain clotting proteins in your blood. It’s used to prevent serious blood clots from forming due to a certain kind of irregular heartbeat, called atrial fibrillation, or after hip- or knee-replacement surgery. In the United States, apixaban is approved to treat certain types of blood clots, such as deep vein thrombosis or pulmonary embolus, and to help prevent them from forming again. Read more about apixaban.
Lisinopril belongs to a class of drugs known as angiotensin-converting enzyme (ACE) inhibitors, and works by relaxing blood vessels so blood can flow more easily. It’s used to treat high blood pressure. Lowering blood pressure helps prevent strokes, heart attacks and kidney problems. It is also used to help treat heart failure and to help improve survival after a heart attack. Read more about lisinopril.
Common generic drugs prescribed to help treat allergies
It is estimated that over 100 million American adults have allergies6, and there are a handful of common generic drugs* used to help reduce these symptoms. Here are some that you may have already heard of.
As an antihistamine, cetirizine works by blocking histamine, a natural substance that your body makes during an allergic reaction. It’s used to relieve allergy symptoms, such as hives, itching, a runny nose, sneezing and watery eyes.
Cetirizine does not prevent hives, nor can it help treat a serious allergic reaction, such as anaphylaxis.
If your doctor has prescribed epinephrine to treat allergic reactions, always carry your epinephrine injector with you. Do not use cetirizine in place of your epinephrine. Read more about cetirizine.
Also an antihistamine, desloratadine works by blocking the action of histamine in your body. It’s used to relieve allergy symptoms, such as hives, itching, a runny nose, sneezing and watery eyes. Read more about desloratadine.
Fexofenadine is another antihistamine used to relieve allergy symptoms, such as hives, itching, a runny nose, sneezing and watery eyes. Read more about fexofenadine.
