5-minute read

Key facts

  • Generic medicines have the same active ingredient as brand-name medicines.
  • They may look different and have different filler ingredients.
  • Generic medicines are often cheaper than brand-name medicines.
  • In Australia, you can only sell generic medicines if they work the same way as the brand-name medicine.
  • Prescribers in Australia must use the name of the active ingredient on prescriptions.

What are brand name medicines?

A pharmaceutical company can give its medicine a brand name. This name is often more memorable and the name used when the medicine is sold.

Generic medicines can be made once the patent expires on the original medicine. A patent protects the intellectual property of new medicines.

What are generic medicines?

A generic medicine is another brand of medicine.

Generic medicines work in the same way as brand-name medicines. They have the same active ingredient as the original brand.

Many medicines with the same active ingredient are available under a number of different brands. This may include an original brand and sometimes several generic brands.

What are active ingredients?

An active ingredient is the chemical that makes the medicine work.

What else do generic medicines contain?

Generic medicines can have different fillers and colours from the original brand. However, all the ingredients must meet the same quality and safety standards.

Do generic medicines look the same as brand name versions?

Generic medicines may be different from the brand-name version in their:

  • colour
  • shape
  • size
  • taste
  • packaging

This is often due to trademark regulations.

Are generic medicines as good as brand-name medicines?

Generic medicines work in the same way as brand-name medicines. They contain the same amount of active ingredient that acts in the same way.

Generic medicines can only be sold in Australia if they meet the same strict standards as the original brand. This covers:

  • quality
  • safety
  • effectiveness

These are checked by the Therapeutic Goods Administration (TGA).

Why are generic medicines often less expensive?

Generic medicines may cost less than brand-name medicines. This is because the manufacturers have not spent money on the medicine's discovery, development and marketing.

Generic medicines must have the same active ingredient as the original medicine. They must also deliver the same amount of active ingredient in the same way as the original brand.

Should I accept a generic medicine?

It's usually your choice whether to buy a brand-name medicine or a generic version, if one is available. Sometimes your doctor will prescribe a specific brand.

Here are some things to consider:

  • A generic medicine may be cheaper than the original brand.
  • You may want to stick with a brand to avoid confusion, especially if you take many different medicines.
  • If you have allergies, you should check whether a generic medicine has ingredients that you are allergic to.
  • Your doctor may recommend you take the original brand for some medicines.

Should I ask for generic medicines?

You can ask your doctor to prescribe a generic medicine. You can also ask your pharmacist if they have a more affordable brand of the same medicine.

Not all medicines have a generic version available.

What is active ingredient prescribing?

Active ingredient prescribing supports the safe prescribing, dispensing and use of medicines.

Under this initiative, Australian health professionals must write the active ingredient on the prescription.

Active ingredient prescribing makes it easier for you to identify medicines that have the same ingredient.

This will help you to avoid:

Active ingredient prescribing also helps you to talk about generic medicines with your doctor. This may reduce your out-of-pocket costs.
