What are some potential problems I could have with a medicine?

Adverse events

Sometimes a medicine or vaccine can cause an 'adverse event'. This is an effect of the medicine that is not intended or wanted and could be a sign, symptom or disease.

Adverse events include unintended side effects (also called adverse drug reactions or adverse effects). Information about common known side effects is listed in the Consumer Medicines Information (CMI) for each medicine.

Adverse events can also include problems with medical devices that are used to administer a medicine. For example, insulin delivery devices.

It's important to remember that adverse events don't always happen because of a problem with the medicine itself. For example, they could be caused by:

• an allergy you may have to the medicine
• incorrect use of the medicine, for example, taking the wrong dose
• the way a medicine's dose is started, then changed

It is also possible for your medicine to interact with another medicine you may be taking. This can affect the way either or both medicines work or how you react to them.

Certain food or drinks can also interact with some medicines and cause an adverse event.

Packaging, handling or storage of medicine

Potential problems include any defects that may occur during the manufacture or distribution of a medicine. These defects could concern either a batch or a single package of the medicine.

Counterfeit medicines and questionable practices

Problems include a medicine being sold without approval in Australia or a manufacturer illegally copying another medicine. There can also be problems with the way a medicine is advertised and any claims a manufacturer makes about it.

What should I do if I have a problem with a medicine?

• It's important to seek advice from a health professional such as your doctor or pharmacist.
• If it's an emergency, call triple zero (000) for an ambulance.
• If your problem is a suspected overdose or poisoning, call the Poisons Information Centre on 13 11 26 (24 hours a day).
• You can also report a problem directly to the TGA yourself. The TGA is the organisation responsible for regulating medicines in Australia.

Can I report problems with a medicine to my healthcare provider?

It's a good idea to tell your doctor or pharmacist about any problem that you're having with a medicine. If you are experiencing an adverse event, they can help you. It might be necessary to stop the medicine, change the dose, or switch to another medicine.

Your doctor or pharmacist should report the problem to the TGA. When they report the problem, your personal information will remain confidential, and your privacy will be respected.

When should I report a problem with a medicine to the TGA?

The TGA monitors the safety of medicines, including any adverse events that a medicine may cause. The TGA can then ensure that this information is available to healthcare professionals and people who take the medicine.

Reports of problems with a medicine can come from anyone, including:

• pharmaceutical companies who make and sell the medicine
• doctors, pharmacists and other healthcare professionals
• hospitals and health departments
• people who take the medicine

By reporting a problem that you have with your medicine, you can play an important role in helping to monitor the safety of the medicine.

The types of medicines and equipment you can report on to the TGA include:

• medicines prescribed by a doctor, including vaccines
• medicines bought at a pharmacy or supermarket (‘over-the-counter' medicines)
• medicines that are complementary or ‘natural', including vitamins and minerals
• medical devices

How do I report a problem to the TGA?

• If you experience an adverse event with a medicine or vaccine, report it directly on the TGA website.
• If you experience a problem with a medical device, report it on the TGA website.
• If you think your medicine has a defect due to manufacture, storage or handling, report it on the TGA website.
• If you think your medicine might not be approved, or there is a questionable manufacturing practice involved, report it on the TGA website.

What is the Black Triangle Scheme?

Resources and support

Find out more about reporting a problem with a medicine from:

• your doctor
• your pharmacist

• the TGA website
• the medicines.org.au website

If you notice an adverse event after taking a medicine and you're not sure what to do, call healthdirect on 1800 022 222 at any time to speak to a registered nurse (known as NURSE-ON-CALL in Victoria) for more information and advice.

The TGA identifies these new medicines with an upside-down black triangle so that healthcare professionals and people who are taking the medicine will be encouraged to report any problems. If a medicine has a black triangle, you will find it in the medicine's CMI.
