The Deereg Tablet is used in the treatment of

• Uterine fibroids
• Emergency Contraceptive

Deereg Tablet, as a selective progesterone receptor modulator (SPRM), is prescribed to help manage the symptoms associated with uterine fibroids by reducing their size and alleviating related discomfort. It works by targeting the progesterone receptors in the body, which are involved in the growth of fibroids and the regulation of menstruation. This medication helps to control menstrual bleeding and decrease the size of fibroids, thus improving the quality of life for women with symptomatic uterine fibroids.

Inform your healthcare provider about all your medicines, including prescription, over-the-counter, nutritional or vitamin supplements, and herbal products. Certain medications may interact with Deereg Tablet and reduce effectiveness by causing undesirable side effects.

• Store in a refrigerator between 20°C to 25°C (68°F to 77°F).
• Keep away from moisture, heat, and light.
• It should not be frozen.
• Keep it in its original packaging until it is ready to be used.
• Keep out of the reach of children and pets.

Deereg Tablet is typically used as a single oral dose for emergency contraception within 120 hours (5 days) of unprotected sexual intercourse. For uterine fibroid treatment, it's usually taken as one tablet daily with or without food for a specified treatment period. To ensure effectiveness, follow your healthcare provider's instructions precisely. If using for emergency contraception, take it immediately after unprotected sex. If taking for fibroids, adhere to the prescribed schedule, and consult your doctor for guidance on any missed doses or concerns.

Like all medications, Deereg Tablets cause some side effects, although not everyone will experience them. 

Serious:

• Severe abdominal pain
• Allergic reactions
• Liver problems (yellowing of the skin or eyes, dark urine, nausea, vomiting, loss of appetite, abdominal pain)

Common:

• Headache
• Nausea
• Abdominal pain or discomfort
• Menstrual changes (heavier or lighter bleeding, changes in cycle)
• Fatigue
• Dizziness

The Deereg Tablet should be approached carefully. Caution is advised for individuals with liver impairments, as the medication is metabolised by the liver. Allergic reactions are possible, necessitating prompt medical attention if symptoms like rash, swelling, or difficulty breathing occur. The impact on menstrual cycles requires monitring, and any significant changes or irregular bleeding patterns should be discussed with a healthcare provider. This medication is not recommended during pregnancy or while breastfeeding due to potential risks. Patients should inform their healthcare providers about their medications to avoid interactions. This medication can interact with certain medications, potentially affecting their effectiveness or causing adverse effects. Drugs that are strong CYP3A4 inducers or inhibitors, such as rifampicin and ketoconazole, can alter its metabolism, while hormonal contraceptives may be less effective if taken concurrently. Additionally, repeated use within a single menstrual cycle and its use in individuals under 18 should be carefully considered. Adherence to prescribed dosages, follow-up appointments, and seeking medical attention for any concerning symptoms is strongly advised.
