About Tretiva
Tretiva is a generic formulation of isotretinoin, a retinoid approved in Australia for the management of severe nodular or cystic acne that has not responded to conventional therapy. By targeting the underlying processes that drive oil production and follicular blockage, isotretinoin can dramatically reduce lesions and improve skin appearance. The medication is supplied as oral tablets in strengths of 5 mg, 10 mg, 20 mg, and 30 mg, and is typically prescribed for a course lasting 4-6 months. While its primary indication is severe acne, clinicians sometimes consider isotretinoin for other dermatologic challenges under specialist supervision.
What is Generic Tretiva (Isotretinoin)?
Generic Tretiva (Isotretinoin) belongs to the class of retinoids, a group of vitamin A-derived compounds that influence cellular differentiation and proliferation. The Therapeutic Goods Administration (TGA) approved isotretinoin for oral use in 1991, and it remains a prescription-only medicine in Australia. As a generic product, Tretiva contains the same active ingredient, dosage forms, and bioavailability as the original branded preparations, ensuring therapeutic equivalence while offering a lower cost option for patients.
How Tretiva Works
Isotretinoin exerts its effect by binding to nuclear retinoic acid receptors (RARs) and retinoid X receptors (RXRs) within keratinocytes and sebaceous gland cells. This interaction modulates gene transcription, leading to three key outcomes:
- Sebaceous gland hypoplasia: Isotretinoin reduces gland size and suppresses sebum synthesis by down-regulating enzymes such as stearoyl-CoA desaturase. Lower sebum creates a less favorable environment for Cutibacterium acnes proliferation.
- Normalization of follicular keratinisation: By encouraging orderly epidermal differentiation, the drug prevents the formation of keratin plugs that block pores.
- Anti-inflammatory activity: Retinoid-mediated inhibition of toll-like receptor pathways dampens inflammatory cytokine release, reducing erythema and lesion tenderness.
Pharmacokinetically, isotretinoin is well absorbed orally, reaching peak plasma concentrations within 2-4 hours. It is metabolised primarily in the liver via cytochrome P450 enzymes (CYP2C8, CYP3A4) and eliminated in the urine and feces. The half-life averages 10-20 hours, allowing once-daily dosing. Food increases absorption by up to 40 %, so clinicians often advise taking the tablet with a meal to improve systemic exposure.
Why Tretiva Is Used for Dermatology Conditions
-
Severe nodular or cystic acne • Mechanistic link: Excess sebum and follicular obstruction are central to lesion formation; isotretinoin directly curtails both. • Guideline position: The Australian Dermatology Society places isotretinoin as a first-line systemic agent after failure of topical and oral antibiotics. • Comparison: Unlike oral tetracyclines, isotretinoin offers a curative course rather than ongoing suppression.
-
Acne vulgaris resistant to conventional therapy • Mechanistic link: Persistent inflammation is mitigated by retinoid-driven cytokine suppression. • Guideline position: Recommended after at least three months of unsuccessful combined topical therapy.
-
Severe seborrhoea-associated dermatoses (e.g., rosacea with papulopustular features) • Mechanistic link: Reduced sebum output diminishes bacterial overgrowth and vascular inflammation. • Guideline position: Considered an adjunct when standard agents (azelaic acid, doxycycline) are insufficient.
-
Certain keratinisation disorders (e.g., ichthyosis vulgaris) • Mechanistic link: Retinoids promote normal epidermal turnover, smoothing hyperkeratotic plaques. • Guideline position: Used off-label under specialist care, usually at lower doses to limit systemic toxicity.
Compared with other oral retinoids such as acitretin, isotretinoin has a more favourable safety profile for acne because it achieves higher skin concentrations at lower systemic exposure.
Off-Label and Investigational Uses of Tretiva
Evidence from small case series and phase II trials suggests isotretinoin may benefit patients with severe acne scarring, where early intervention can limit collagen disruption. Additionally, investigators have explored low-dose isotretinoin as adjunctive therapy for basal cell carcinoma prevention in high-risk individuals, though data remain preliminary.
Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Tretiva Right for You?
Ideal candidates are adolescents or adults with severe nodular or cystic acne unresponsive to topical regimens and oral antibiotics. The drug is contraindicated in pregnancy due to its potent teratogenicity, and women of child-bearing potential must use reliable contraception throughout treatment and for one month after discontinuation. Patients with severe hepatic impairment, hyperlipidaemia, or a history of inflammatory bowel disease require careful monitoring or may be better served by alternative therapies. Elderly patients generally tolerate isotretinoin similarly to younger adults, although dose adjustments may be prudent if renal function is reduced.
Taking Tretiva Effectively
- Timing: Take the tablet once daily with a full glass of water and a meal to maximise absorption.
- Food interactions: High-fat meals boost bioavailability; however, consistent timing with meals helps maintain stable plasma levels.
- Missed dose: If a dose is missed and the next scheduled dose is more than 12 hours away, skip the missed tablet and resume the regular schedule; do not double-dose.
- Travel: Carry the medication in its original packaging with a copy of the prescription; isotretinoin is a controlled substance in some jurisdictions, and border checks may occur.
- Lifestyle: Avoid excessive sun exposure and use broad-spectrum sunscreen (SPF 30 +) because isotretinoin heightens photosensitivity.
Understanding Side Effects and How to Manage Them
- Dry skin and mucous membranes - Result from reduced sebum and altered keratinisation. Apply emollient moisturisers twice daily and use lip balm with petroleum jelly.
- Elevated liver enzymes and triglycerides - Isotretinoin is metabolised hepatically and influences lipid metabolism. Baseline liver function tests and lipid panels are required; repeat monitoring at 4-week intervals. If levels rise >2 × ULN, dose reduction or temporary cessation is advised.
- Musculoskeletal pain - May stem from altered collagen turnover. Light stretching, adequate hydration, and low-impact exercise can alleviate discomfort.
- Mood changes - Rare but reported; any emergence of depressive symptoms warrants immediate medical evaluation.
- Severe reactions (e.g., pseudotumor cerebri, pancreatitis) - Recognise warning signs such as persistent headache, visual disturbances, or acute abdominal pain. Seek urgent care if they occur.
Most adverse events are dose-dependent and improve with dose tapering or after treatment completion.

Frequently Asked Questions
-
What should I expect during the first two weeks of treatment? Initial weeks often involve increased skin dryness and occasional flaring of acne lesions, a phenomenon known as the “retinoid flush.” These effects usually subside as the skin adjusts.
-
Can I take Vitamin A supplements while on Tretiva? Concomitant high-dose Vitamin A is not recommended because it can exacerbate toxicity. Normal dietary intake poses no risk.
-
How long will the treatment last? The typical course spans 4-6 months, aiming for a cumulative dose of 120-150 mg/kg body weight to minimise relapse.
-
Is it safe to drive while on Tretiva? Most patients experience no impairment in cognitive or motor function. However, if you notice dizziness or visual disturbances, avoid operating heavy machinery until resolved.
-
Will I need blood tests? Yes. Baseline liver function, fasting lipid profile, and pregnancy test (for women) are required, followed by periodic monitoring every 4-8 weeks.
-
How does Tretiva compare to oral antibiotics for acne? Antibiotics suppress bacterial overgrowth but do not address sebum production or follicular hyperkeratinisation. Isotretinoin offers a disease-modifying effect, often leading to lasting remission after a single course.
-
Can men use Tretiva without contraception? While teratogenicity is a concern only for female patients, men should still inform their healthcare provider of any plans for future fatherhood, as isotretinoin can be detected in seminal fluid.
-
What happens if I miss a dose? Skip the missed tablet and continue with the next scheduled dose. Do not double-dose to compensate.
-
Is isotretinoin effective for adult acne? Yes. Studies show comparable clearance rates in adults as in adolescents, particularly for hormonal-driven lesions.
-
Are there any natural alternatives? Topical retinoids, zinc supplements, and dietary modifications can provide modest benefits, but they lack the robust, curative impact of systemic isotretinoin for severe disease.
