TGA Product Information Safety Updates 17 February

TGA

When new safety information for medicines is identified, the Therapeutic Goods Administration (TGA) works with the sponsors to update Product Information (PI) to ensure that health professionals and consumers have access to this information. New safety information can be identified through the TGA's ongoing safety monitoring activities or uncovered and submitted by sponsors themselves. Please see below details of some medicines that have recently had safety related updates to their PI.

The TGA monitors the safety of medicines marketed in Australia using:

Changes to the PI that result from TGA safety monitoring activities may:

  • narrow indications
  • add or modify specific sections, such as:
    • contraindications
    • warnings or precautions
    • use in fertility, pregnancy and lactation
    • use in special populations
    • adverse effects.

It is important for prescribers and other health professionals to be aware of safety-related PI changes, as they may require you to take actions or do things differently, such as:

  • counsel patients on identified risks
  • undertake special monitoring or precautions
  • in some instances select alternate medications.

Significant PI changes are often supported by distribution of a Dear Health Care Professional Letter on the issue, which are produced by the medicine's sponsor and sent directly to health professionals.

We will publish a Medicines Safety Update (MSU) article detailing recent safety-related PI updates each month, although this may not include all safety-related updates. We will continue to publish MSU articles for critical safety issues or topics of special interest.

The below medicines are generally innovator brands (generic brands may be included in some circumstances). Generic brands containing the same active ingredients as the medicines below are required to align with the safety information in the innovator's PI and will be updated accordingly.
