Nacrez (Desogestrel)

Desogestrel, the active ingredient in Nacrez, is a progestin presented as an oral tablet for oral use. It is used for prevention of pregnancy in women of reproductive age. GNH USA supplies Nacrez as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Desogestrel acts as a progestin‑only hormonal contraceptive to prevent pregnancy. - Prevention of pregnancy: provides reliable hormonal birth control for women of reproductive age. - Regulation of menstrual bleeding: helps achieve more predictable menstrual cycles when used as a progestin‑only pill. - Management of ovulation‑related disorders: suppresses ovulation in conditions where ovulation control is desired.

Desogestrel may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects: - Nausea: mild stomach upset that usually resolves with continued use. - Headache: occasional tension‑type headaches. - Breast tenderness: mild discomfort or swelling of the breasts. - Irregular bleeding: spotting or changes in menstrual flow. - Mood changes: mild fluctuations in mood or emotional state. - Weight gain: slight increase in body weight.

Serious or Rare Side Effects: - Thromboembolic events: deep vein thrombosis or pulmonary embolism. - Severe allergic reaction: rash, itching, swelling, or anaphylaxis. - Liver dysfunction: jaundice or abnormal liver function tests. - Severe hypertension: sudden increase in blood pressure. - Vision changes: rare cases of visual disturbances.

Before prescribing Desogestrel, clinicians should consider several safety factors. - Cardiovascular risk assessment: evaluate history of thrombosis or smoking over age 35. - Liver function evaluation: avoid use in patients with active liver disease. - Smoking status: counsel smokers, especially those over 35, about increased risk. - Medication review: check for drugs that may reduce contraceptive efficacy. - Missed dose guidance: provide instructions on what to do if a dose is missed. - Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Desogestrel can interact with other medicines, affecting its effectiveness or safety.

Major Interactions (Avoid): - Rifampin: strong CYP3A4 inducer that may reduce contraceptive efficacy. - Phenytoin: enzyme inducer that can lower desogestrel plasma levels. - Carbamazepine: reduces hormonal contraceptive effectiveness.

Moderate Interactions (Monitor Closely): - Ketoconazole: may increase desogestrel concentrations. - Antifungal azoles (e.g., fluconazole): can elevate hormone levels. - Certain antidepressants (e.g., sertraline): may modestly affect metabolism.
