Tretiva Isotretinoin 40mg Capsules

Q1: What is Tretiva 40mg (Intas Isotretinoin 40mg) used for?

Tretiva 40mg is a high-dose isotretinoin for severe cystic acne in adults requiring intensive treatment. It is appropriate for patients weighing 80–160kg at 0.5 mg/kg/day, achieving the cumulative target dose more rapidly than lower doses.

Q2: Who needs the 40mg dose?

40mg is prescribed for: heavier patients (80kg+) needing standard 0.5 mg/kg/day dose, patients who relapsed after lower-dose courses and require more intensive therapy, or patients with very severe fulminant acne where rapid response is prioritised.

Q3: What is the acne clearance rate at 40mg?

Like all isotretinoin strengths, Tretiva 40mg achieves approximately 80–90% long-term acne remission after a complete course. The higher dose may provide a shorter course duration and potentially more complete sebaceous gland suppression.

Q4: What is the teratogenicity requirement for 40mg?

Identical to all other doses — two forms of contraception, monthly pregnancy tests, and 1 month post-treatment contraception are mandatory. The teratogenicity risk is highest at higher doses.

Q5: What are the most common side effects at 40mg?

Severe dry lips and skin, significant joint and muscle pain (myalgia/arthralgia), marked triglyceride elevation, and intense skin dryness are characteristic of high-dose treatment. Strict moisturising and lipid monitoring are essential.

Q6: What blood test monitoring is required at 40mg?

Monthly liver function tests and fasting lipid panel are critical at 40mg. Triglycerides often rise significantly — if they exceed 500 mg/dL, the dose must be reduced or treatment interrupted to prevent pancreatitis risk.

Q7: What dietary changes help at 40mg?

Reduce dietary fat intake to help manage triglyceride elevation. Avoid alcohol entirely (additive liver and lipid effects). A low-fat diet during the course minimises hypertriglyceridemia and liver enzyme elevation.

Q8: What eye care is needed at this dose?

Dry eyes are very common at 40mg. Use preservative-free artificial tears frequently. Minimize contact lens wear and switch to glasses during treatment if comfortable. Report any vision changes immediately.

Q9: What psychiatric effects should I watch for?

Depression, anxiety, mood swings, and irritability have been reported with isotretinoin — more concern with higher doses. Inform family to monitor mood. Report any significant psychological changes to your dermatologist immediately.

Q10: How long should I wait before cosmetic procedures?

Wait at least 6 months after completing the 40mg course before any skin procedures. At higher cumulative doses, skin healing may remain impaired longer than with lower-dose courses.

Q11: How should Tretiva 40mg 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 40mg?

Yes. This high-dose isotretinoin formulation requires a dermatologist prescription with mandatory pregnancy prevention protocol, monthly laboratory monitoring, and close clinical supervision.
