Isotretinoin 20mg—commonly known by brand names like Accutane—is one of the most powerful and effective treatments for severe or treatment-resistant acne. While it offers life-changing results for many, it’s also a medication that demands careful planning, monitoring, and awareness of its effects. In this article, we’ll guide you through what to expect before, during, and after an isotretinoin course.
What Is Isotretinoin?
Isotretinoin is a vitamin A derivative (retinoid) that drastically reduces the size and activity of sebaceous (oil) glands. This lowers sebum production, unclogs pores, and has anti-inflammatory effects—all of which are crucial in combating severe nodular or cystic acne.
It’s usually prescribed only after topical treatments, antibiotics, or hormonal therapies fail to deliver sufficient results.
Before Starting Isotretinoin: What You Should Know
1. Consultation and Evaluation
Before starting isotretinoin, a dermatologist will evaluate your acne severity, medical history, and any past treatments. This may involve:
- Physical examination of your acne
- Reviewing other treatments you’ve tried
- Discussing potential side effects
- Blood tests to check liver function, cholesterol, and triglyceride levels
2. Pregnancy Prevention
Isotretinoin is highly teratogenic, meaning it can cause severe birth defects. For this reason:
- Women of childbearing age must use two forms of contraception
- A negative pregnancy test is required before, during, and after treatment
- Some countries (like the U.S.) have iPLEDGE programs to regulate its use
3. Mental Health Screening
Some patients report mood changes, depression, or anxiety while on isotretinoin. A mental health history may be assessed before treatment begins.
During Isotretinoin Treatment: What to Expect
A typical isotretinoin course lasts 4 to 6 months, though it may vary based on acne severity and response to the medication.
1. Initial Breakout (“Purge”)
In the first few weeks, acne may temporarily worsen before getting better. This is known as the “initial purge” and occurs as clogged pores are rapidly cleared out.
2. Dosage and Monitoring
Dosage is usually based on your weight (commonly 0.5–1 mg/kg/day). Your doctor may start low to minimize side effects and gradually increase it.
Monthly checkups are necessary to:
- Monitor liver enzymes and cholesterol
- Ensure proper contraception in women
- Track mental and physical side effects
3. Common Side Effects
Some side effects are expected and manageable, including:
- Dry skin and lips (almost universal)
- Dry eyes or contact lens discomfort
- Nosebleeds from dry nasal passages
- Joint or muscle pain
- Sun sensitivity
Using gentle skincare, lip balms, and sunscreens can help manage these effects.
4. Lifestyle Adjustments
To avoid complications during treatment:
- Avoid waxing, laser hair removal, and harsh peels (due to fragile skin)
- Limit alcohol intake
- Stick to a gentle skincare routine
- Avoid vitamin A supplements (to prevent toxicity)
5. Emotional and Physical Monitoring
While rare, emotional changes like mood swings or depression should be reported to your doctor immediately. Open communication is essential.
After Isotretinoin: Recovery and Results
1. Clearer Skin
Most patients experience significant to complete acne clearance by the end of their isotretinoin course. The results are often long-lasting or permanent.
Studies suggest that up to 85% of patients don’t need further treatment, although some may require a second course later.
2. Side Effects Subside
Many side effects—like dryness and sun sensitivity—begin to resolve within a few weeks to months after stopping the medication.
Blood levels of isotretinoin drop quickly, but lingering effects on skin and oil production can persist for a while.
3. Scarring and Skin Healing
While isotretinoin prevents new breakouts, it doesn’t treat existing acne scars. Once your skin has healed for several months, your dermatologist may recommend:
- Laser treatments
- Microneedling
- Chemical peels
- Fillers
These procedures are usually delayed for 6–12 months post-treatment to avoid irritation.
4. Skincare After Isotretinoin
Post-treatment skin remains delicate for some time. Focus on:
- Hydrating moisturizers
- Gentle cleansers
- Daily SPF (broad-spectrum sunscreen)
Avoid strong active ingredients like retinoids or AHAs for at least a few months unless your dermatologist approves.
Who Should Avoid Isotretinoin?
Isotretinoin is not for everyone. It may be unsuitable for:
- Pregnant or breastfeeding women
- People with certain liver disorders
- Individuals with severe depression or mental health conditions (depends on case)
- Patients with high cholesterol or triglycerides
Your doctor will weigh benefits and risks before prescribing.
