Isotretinoin, the active ingredient in Isotretinoin Sun, is a retinoid presented as an oral formulation for oral use. It treats severe nodular acne and other forms of acne vulgaris in patients who have not responded to conventional therapy.

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

Isotretinoin is a systemic retinoid used to manage severe acne conditions by targeting sebaceous gland activity.

Severe nodular acne: reduces inflammatory lesions and prevents new comedone formation. Acne vulgaris (moderate to severe): improves skin clearance and decreases lesion count. Cystic acne: diminishes deep, painful nodules and promotes faster healing.

Isotretinoin may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Dry skin and mucous membranes - Cheilitis (cracked lips) - Photosensitivity - Arthralgia or muscle aches - Elevated liver enzymes

Serious or Rare Side Effects: - Severe depression or suicidal ideation - Inflammatory bowel disease - Pancreatitis - Severe liver injury - Teratogenic effects in pregnancy - Pseudotumor cerebri

When prescribing isotretinoin, clinicians should observe several safety measures to minimize risks.

Pregnancy contraindication: avoid use in pregnant women; ensure effective contraception. Teratogenic risk: require two negative pregnancy tests before initiation and monthly thereafter. Liver function monitoring: check ALT/AST levels prior to and during therapy. Lipid monitoring: assess serum triglycerides and cholesterol regularly. Mood and psychiatric assessment: monitor for depression, anxiety, or suicidal thoughts. Store at below 25°C: keep in original packaging, protect from moisture and light.

Isotretinoin can interact with other medicines, altering its safety or effectiveness.

Major Interactions (Avoid): - Tetracycline antibiotics: increased risk of intracranial hypertension. - Vitamin A supplements or other retinoids: additive toxicity, especially hepatic. - Systemic corticosteroids: may exacerbate pseudotumor cerebri risk.

Moderate Interactions (Monitor Closely): - Antifungal agents (e.g., ketoconazole): may affect liver enzyme metabolism. - Oral contraceptives: isotretinoin may reduce efficacy; additional contraceptive methods recommended. - Diuretics (e.g., thiazides): may increase serum uric acid and lipid levels.
