Recommended Dosage:

Emergency Contraception: 30 mg as a single oral dose.
Uterine Fibroids: 5 mg daily for up to 3 months, under the guidance of a healthcare provider.

Directions:

Take the medication as soon as possible after unprotected sex for emergency contraception.
Ulipristal can be taken with or without food.
Follow your doctor’s instructions carefully when using for uterine fibroids.

Cautions:

Pregnancy: Ulipristal should not be used if you are already pregnant. If pregnancy occurs after taking ulipristal, consult your healthcare provider immediately.
Breastfeeding: Not recommended during breastfeeding as ulipristal may pass into breast milk.
Other Medications: Be cautious if taking ulipristal with other medications, particularly hormonal contraceptives, as they may interfere with its effectiveness.
