Tretiva 40mg Capsule contains isotretinoin 40 mg, a prescription retinoid used to treat severe acne that has not responded adequately to conventional treatments. It can be particularly useful for severe inflammatory or nodular acne when topical medicines and other treatments have not provided sufficient improvement. Because isotretinoin can cause serious adverse effects, patients should use it only under the supervision of a qualified healthcare professional. Product information identifies Tretiva 40 Capsule as isotretinoin 40 mg manufactured by Intas Pharmaceuticals Ltd.

What Is Tretiva 40mg Capsule?

Tretiva 40mg Capsule is an oral medicine containing isotretinoin, a vitamin-A derivative belonging to the retinoid class. Doctors generally reserve isotretinoin for severe acne, particularly acne that causes deep nodules, significant inflammation, scarring, or persistent breakouts despite other appropriate treatments. FDA-approved isotretinoin products are indicated for severe recalcitrant nodular acne in appropriate patients.

Rather than simply treating an individual pimple, isotretinoin acts on several processes involved in acne development. It substantially reduces activity of the sebaceous glands and decreases sebum production. It also influences abnormal follicular keratinization and helps reduce the conditions that allow acne lesions to develop. These combined effects can produce substantial and sometimes prolonged improvement in severe acne.

How Does Tretiva 40mg Capsule Work?

The active ingredient, isotretinoin, reduces the amount of oil produced by sebaceous glands. Excessive sebum can contribute to blocked pores and create an environment in which acne develops. By reducing sebaceous-gland activity, isotretinoin helps decrease the formation of new acne lesions.

The medicine also affects the way skin cells develop and shed inside hair follicles. This can help reduce blockage and inflammation. Treatment therefore addresses several underlying mechanisms rather than simply drying individual lesions.

The response does not occur overnight. Acne may initially fluctuate, and improvement develops progressively during treatment. Your dermatologist determines whether isotretinoin remains appropriate based on your acne severity, response, laboratory results, and tolerability.

Who May Need Isotretinoin Treatment?

Doctors typically consider isotretinoin when acne is severe, persistent, scarring, or inadequately controlled with other appropriate therapies. FDA information describes isotretinoin as a treatment for severe acne that has not cleared with other treatments, including antibiotics.

A dermatologist should evaluate your skin and medical history before prescribing this medicine. The dose should not be selected solely from the capsule strength shown on the package. Your healthcare professional considers factors such as body weight, treatment response, adverse effects, medical conditions, and other medicines.

Important Pregnancy Warning

Pregnancy safety is the most important consideration with isotretinoin. Isotretinoin can cause severe, life-threatening birth defects and must not be used during pregnancy. FDA therefore requires a restricted risk-management program for isotretinoin in the United States.

Anyone who can become pregnant must follow the pregnancy-prevention and testing requirements established by the prescriber and applicable regulatory program. If pregnancy occurs while taking isotretinoin, stop taking the medicine and contact your healthcare professional immediately for appropriate medical advice.

The FDA approved modifications to the iPLEDGE REMS in February 2026, although implementation of those modifications has been delayed until November 15, 2026. Patients should therefore follow the requirements currently provided by their prescriber and dispensing pharmacy rather than relying on older online information.

Common Side Effects

Isotretinoin commonly causes dryness because it reduces oil production. Patients may experience dry or peeling skin, chapped lips, dry eyes, eye irritation, and nasal dryness. Headache and other adverse effects can also occur.

Using a gentle moisturizer and lip balm can help manage dryness. Patients should avoid unnecessarily irritating skincare products and discuss significant skin reactions with their healthcare professional.

More serious adverse effects can involve the liver, blood lipids, eyes, nervous system, or mental health. Seek medical attention promptly for severe headache with visual changes, significant mood changes, severe abdominal pain, yellowing of the skin or eyes, or other concerning symptoms.

Monitoring During Treatment

Your prescriber may order blood tests during treatment. Depending on your circumstances and the specific isotretinoin product, monitoring may include liver function and fasting lipid levels. FDA prescribing information identifies lipid abnormalities and hepatotoxicity among important safety considerations.

Do not skip recommended appointments simply because your acne appears better. Monitoring helps your healthcare professional determine whether treatment remains safe and appropriate.

Important Drug and Supplement Considerations

Tell your doctor and pharmacist about every prescription medicine, over-the-counter product, vitamin, and supplement you use. Particular interactions and precautions exist with vitamin-A supplements and certain medicines, including tetracycline antibiotics. The FDA prescribing information also identifies several other potential interactions.

Avoid taking additional vitamin-A supplements unless your healthcare professional specifically recommends them. Never change your isotretinoin dose or combine it with another acne medicine without professional guidance.

Storage and Handling

Keep the capsules in their original packaging and store them according to the product label and pharmacist’s instructions. Keep all prescription medicines away from children and other people who have not been prescribed the medication.

Do not share isotretinoin capsules with another person. A capsule that is appropriate for one patient may be dangerous for someone else, particularly because of the serious pregnancy-related risks.
