Isotretinoin 20mg is a powerful oral medication widely used to treat severe acne, especially when other treatments fail. Known by brand names like Accutane, this drug has transformed the lives of many people struggling with persistent acne. However, like any strong medication, it comes with a range of side effects that users should clearly understand before starting treatment.
This guide explains the most common side effects of Isotretinoin, why they happen, and how to manage them safely.
The most common side effects of isotretinoin include dry skin, chapped lips, dry eyes, nosebleeds, joint pain, and increased sensitivity to sunlight. These effects occur because the medication reduces oil production in the skin.
Why Does Isotretinoin Cause Side Effects?
Isotretinoin works by shrinking the sebaceous (oil) glands and reducing sebum production. While this helps prevent acne, it also removes the skin’s natural moisture barrier, leading to dryness and irritation.
Additionally, isotretinoin affects cell turnover and inflammation, which can trigger other systemic side effects.
Most Common Side Effects of Isotretinoin
1. Dry Skin and Peeling
This is the most reported side effect. You may notice:
- Flaky skin
- Tightness or irritation
- Peeling, especially around the nose and mouth
Why it happens: Reduced oil production dries out the skin.
Tip: Use a gentle, fragrance-free moisturizer daily.
2. Chapped Lips (Cheilitis)
Almost everyone taking Isotretinoin experiences dry, cracked lips.
- Lips may become sore or bleed
- Lip balm becomes essential
Tip: Apply a hydrating lip balm frequently throughout the day.
3. Dry Eyes and Vision Issues
Isotretinoin can reduce tear production, leading to:
- Eye dryness
- Irritation or redness
- Difficulty wearing contact lenses
In some cases, people report night vision problems.
Tip: Use lubricating eye drops if needed.
4. Nosebleeds (Epistaxis)
Dry nasal passages can lead to:
- Frequent nosebleeds
- Nasal irritation
Why it happens: The inner lining of the nose becomes dry and fragile.
Tip: Apply a small amount of petroleum jelly inside the nostrils.
5. Sun Sensitivity
Your skin becomes more sensitive to UV rays while on Isotretinoin.

This side effect is more common in physically active individuals.
