Isotrenol 20 Capsule 10 is used to treat severe, stubborn, or cystic acne by reducing oil production, preventing clogged pores, and controlling bacterial growth. It helps achieve clearer skin and reduces the risk of long-term acne scars.

Swallow the capsule whole, without breaking or chewing it.
Always take the capsule with food, as it can boost the absorption of isotretinoin.
Do not exceed the dose recommended by your doctor.
Ensure you consult your doctor before adjusting your dosage or stopping the medication.

Isotrenol 20 Capsule 10 is taken orally.

Common side effects of Isotrenol 20 Capsule 10 are dry, peeling skin, itchy or red skin, dry and irritated eyes, joint and muscle aches, skin thinning, and nosebleeds. These symptoms may vary in severity.

Managing the Side Effects:

Most side effects are temporary and generally harmless, which resolve on discontinuing the use of Isotrenol 20 Capsule 10. However, if you experience any serious side effects or worsening of any of the symptoms, please consult your doctor.

Here are some general guidelines for managing common side effects:

Dry, peeling skin: If you have dry or peeling skin, consider applying a moisturiser after taking this medicine.
Nosebleeds: To manage nosebleeds, try taking medicine with a good amount of water.

Isotrenol 20 Capsule 10 contains isotretinoin (20 mg), which acts on your body in the following ways:

Reduces Sebum Production: Isotretinoin works by decreasing the size and output of sebaceous glands—glands in your skin that produce an oily substance called sebum. Less sebum makes your pores less likely to get blocked and inflamed.
Alters Cell Growth: Isotretinoin, a derivative of vitamin A, alters DNA transcription. This process affects how skin cells grow and differentiate.
Prevents Pore Clogging: Isotretinoin makes your skin cells less "sticky", preventing them from clumping together and clogging pores.
Hinders Bacterial Growth: Isotretinoin also inhibits the growth of Propionibacterium acnes, a type of bacteria that causes acne.
