Frequently Asked Questions
Q1: What is Tretiva 20mg (Intas Isotretinoin 20mg) used for?
Tretiva 20mg by Intas Pharmaceuticals treats moderate to severe cystic and nodular acne that has failed antibiotics or topical therapy. 20mg is the most commonly prescribed isotretinoin strength for adult patients weighing 40–60kg at standard 0.5 mg/kg/day dosing.
Q2: How does Tretiva 20mg provide long-term acne remission?
Isotretinoin at the 20mg dose provides enough cumulative dose to permanently shrink sebaceous glands, normalize skin cell turnover, eliminate acne-causing bacteria, and reduce inflammation — leading to long-term or permanent remission in 80–90% of patients.
Q3: When will I see results from Tretiva 20mg?
Skin improvement typically becomes visible from 6–8 weeks. An initial acne flare (temporary worsening) in the first 4–6 weeks is expected. Complete clearance occurs by the end of the full course.
Q4: How long is a Tretiva 20mg course?
For a 60kg patient at 20mg/day, achieving 120–150 mg/kg cumulative dose takes approximately 6 months. Your dermatologist determines exact duration based on weight, response, and tolerability.
Q5: What is the mandatory pregnancy prevention protocol?
Isotretinoin at all doses is severely teratogenic. Women must use TWO effective contraception forms throughout treatment and for 1 month after stopping. Monthly pregnancy tests are mandatory. Failure to comply risks catastrophic fetal harm.
Q6: What are the most common side effects at 20mg?
Dry lips (requiring constant lip balm), dry skin (needing regular moisturiser), nosebleeds, dry eyes, joint pain, and initial acne flare are expected. Intense moisturising care significantly reduces discomfort.
Q7: Can I drink alcohol while taking Tretiva 20mg?
No. Avoid alcohol during the entire treatment. Both isotretinoin and alcohol are processed by the liver; combined use raises liver enzymes and triglycerides significantly.
Q8: What blood tests are required?
Liver function tests (ALT, AST) and fasting lipid panel at baseline and monthly throughout the course. Female patients: monthly pregnancy tests. These safety requirements apply across all isotretinoin brands and strengths.
Q9: What cosmetic procedures must be avoided?
Avoid during treatment and for 6 months after: waxing, laser resurfacing, dermabrasion, chemical peels, and tattooing. Isotretinoin impairs wound healing and skin regeneration for months after treatment.
Q10: Does Tretiva 20mg cause mood changes?
Depression, anxiety, and mood changes have been reported with isotretinoin. Report any significant mood changes to your dermatologist promptly. Family members should also be informed to monitor for behavioural changes.
Q11: How should Tretiva 20mg be stored?
Store at room temperature (15°C–30°C) away from light and moisture. Keep in original blister packs.
Q12: Do I need a prescription for Tretiva 20mg?
Yes. All isotretinoin formulations including Tretiva require a dermatologist prescription with mandatory pregnancy prevention compliance and monthly monitoring.
