Nacrez (Desogestrel)

Desogestrel, the active ingredient in Nacrez, is a progestogen presented as an oral tablet for oral use. It is employed as a hormonal contraceptive to prevent pregnancy in women of reproductive age and works by suppressing ovulation and altering the endometrial lining, providing reliable birth control.

GNH USA supplies Nacrez as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Desogestrel, marketed as Nacrez, is indicated for hormonal contraception and related menstrual management.

- Prevention of pregnancy: provides reliable contraception by inhibiting ovulation. - Menstrual cycle regulation: helps achieve predictable withdrawal bleeding patterns. - Estrogen‑free contraceptive option: offers a progestogen‑only method for women who cannot use estrogen‑containing products.

Desogestrel may be associated with a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Irregular vaginal bleeding or spotting. - Headache. - Nausea. - Breast tenderness. - Weight gain. - Mood changes.

Serious or Rare Side Effects: - Deep vein thrombosis or pulmonary embolism. - Severe allergic reaction (anaphylaxis). - Liver dysfunction or jaundice. - Depression or severe mood disorders. - Hypertension. - Unexplained vaginal bleeding.

Before prescribing Nacrez, clinicians should evaluate individual risk factors and counsel patients on safe use.

- Assess medical history: evaluate risk factors for thromboembolism. - Avoid use in known estrogen‑dependent tumors. - Monitor blood pressure: watch for hypertension. - Consider liver function: adjust if hepatic impairment is present. - Counsel on smoking: avoid in women over 35 who smoke more than 15 cigarettes per day. - Store at ambient temperature: keep in the original pack, protect from moisture.

Desogestrel can interact with several drug classes, altering its contraceptive efficacy or increasing adverse effects.

Major Interactions (Avoid): - Antiepileptic enzyme inducers (e.g., carbamazepine, phenytoin): reduce contraceptive effectiveness. - Rifampicin: decreases plasma levels of desogestrel. - St. John’s wort: may lower contraceptive efficacy.

Moderate Interactions (Monitor Closely): - Antifungal azoles (e.g., ketoconazole): may increase desogestrel levels. - Antiretroviral protease inhibitors (e.g., ritonavir): may affect metabolism. - Combined hormonal therapy (estrogen): may increase risk of thromboembolism.
