Microstad (Ethinylestradiol, Levonorgestrel)

Ethinylestradiol, the active ingredient in Microstad, is a combined oral contraceptive presented as a tablet for oral use. It works together with levonorgestrel to prevent pregnancy in women of reproductive age.

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

Microstad is a combined oral contraceptive that acts on the hormonal regulation of the menstrual cycle.

Prevention of pregnancy: provides reliable contraceptive protection for women of childbearing age. Menstrual cycle regulation: helps achieve more predictable bleeding patterns and reduces dysmenorrhea. Acne improvement: may reduce acne associated with hormonal fluctuations in some users.

Microstad may cause a range of adverse reactions, which are generally classified by frequency.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Headache: tension‑type or migraine‑like pain. - Breast tenderness: swelling or discomfort. - Irregular vaginal bleeding: spotting or breakthrough bleeding.

Serious or Rare Side Effects: - Deep vein thrombosis: blood clot formation in deep veins. - Pulmonary embolism: clot migration to lung vessels. - Severe allergic reaction (anaphylaxis): rash, swelling, difficulty breathing.

When prescribing Microstad, healthcare professionals should consider several precautionary measures to ensure safe use.

Medical history review: assess for risk factors such as thromboembolic disease, cardiovascular disorders, or liver dysfunction. Smoking status: avoid use in women over 35 who smoke heavily. Concurrent medications: evaluate for drugs that may reduce contraceptive efficacy. Pregnancy testing: confirm non‑pregnant status before initiation. Store at ambient temperature: keep tablets in original packaging, protect from moisture and heat.

Microstad can interact with other medicines, altering its effectiveness or increasing risk of adverse events.

Major Interactions (Avoid): - Antiepileptic enzyme inducers (e.g., carbamazepine, phenytoin): may markedly reduce contraceptive hormone levels. - Antiretroviral protease inhibitors (e.g., ritonavir): can increase hormone concentrations, raising risk of side effects.

Moderate Interactions (Monitor Closely): - Antibiotics (e.g., rifampin): may modestly decrease effectiveness, consider backup contraception. - Herbal supplements containing St. John’s wort: may lower hormone levels, monitor for breakthrough bleeding. - Selective serotonin reuptake inhibitors (SSRIs): may increase risk of mood changes, monitor patient.
