1. What Gepex 25 mg film-coated tablets are and what they are used for

Exemestane belongs to a group of medicines called aromatase inhibitors. These medicines interfere with aromatase, necessary for producing female sex hormones (estrogens), especially in postmenopausal women. The reduction of estrogen levels in the body is a form of treatment for hormone-dependent breast cancer.

Exemestane is used to treat hormone-dependent breast cancer in early stages in postmenopausal women after they have completed 2-3 years of treatment with the medicine tamoxifen.

Exemestane is used to treat advanced hormone-dependent breast cancer in postmenopausal women when other hormonal treatment has not been effective enough.

2. What you need to know before you take Gepex 25 mg film-coated tablets

Do not take Gepex:

  • if you are allergic (hypersensitive) to exemestane or any of the other ingredients of this medicine. See section 6 (“Composition of Gepex”) for the complete list of excipients
  • if you have not reached menopause, i.e., if you still have your period
  • if you are pregnant, think you may be pregnant, or are breastfeeding

Warnings and precautions

  • Consult your doctor or pharmacist before starting to take Gepex.
  • Before starting treatment with Exemestane, your doctor may perform a blood test to ensure that you have reached menopause.
  • Periodically, your vitamin D levels will also be reviewed before starting treatment, as they may be too low in the early stages of breast cancer. You will be given a vitamin D supplement if your levels are below normal.
  • Before taking Gepex, inform your doctor if you have any liver or kidney problems.
  • Tell your doctor if you have a history of or suffer from any disease that affects bone strength. Your doctor may analyze your bone density before and during treatment with Gepex. This is because medicines in this group reduce female hormone levels, which can lead to a loss of bone mineral content and may decrease bone strength.

Other medicines and Gepex

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including those obtained without a prescription.

Gepex must not be administered at the same time as hormone replacement therapy (HRT).

Other medicines should be used with caution in combination with Exemestane. Let your doctor know if you are taking rifampicin (an antibiotic), carbamazepine, or phenytoin (used for epilepsy). You should also inform your doctor if you are taking the herbal medicine St. John's Wort (Hypericum perforatum) or other preparations that contain it.

Pregnancy and breastfeeding

You must not use Exemestane if you are pregnant or think you may be pregnant.

You must not use Exemestane if you are breastfeeding.
