Reduce the severity of existing acne and promote faster healing.

Replace older, damaged skin with newer skin, which can improve the appearance of fine wrinkles, dark spots, and rough patches caused by sun damage.

Oral Use

When taken by mouth, tretinoin is used to treat a specific type of blood cancer called acute promyelocytic leukemia. It works by:

Helping immature blood cells grow and mature into normal, functioning cells.

Stopping the rapid and uncontrolled growth of cancerous cells in the bone marrow and blood.

Question 8

What is the dosage of Tretinoin and how do I take it?

Accepted Answer

Topical Application

Topical tretinoin is usually applied once daily, often in the evening before bedtime. Before application, wash the skin with a mild soap and pat it dry. It is generally recommended to wait 20 to 30 minutes after washing before applying the medication to help minimize skin irritation.

Use only enough medication to cover the affected area thinly. Avoid contact with the eyes, nose, mouth, and open wounds. Wash your hands immediately after applying the medication.

Oral Administration

Oral tretinoin capsules are typically taken twice a day. These should be taken with food and swallowed whole. Do not crush, chew, or break the capsules.

Missed Dose

If you miss a dose, use or take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your regular dosing schedule. Do not use double doses to make up for a missed one.

Question 9

Is Tretinoin safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Oral tretinoin is known to cause severe birth defects if taken during pregnancy. Because of these risks, healthcare providers require strict pregnancy prevention measures, including multiple forms of effective birth control and regular pregnancy testing, before and during treatment. Oral tretinoin should not be used by individuals who are pregnant or planning to become pregnant.

Topical tretinoin is applied to the skin, and only a small amount is absorbed into the bloodstream. However, because oral retinoids are highly teratogenic (causing birth defects), many healthcare providers recommend avoiding topical tretinoin during pregnancy as a precautionary measure. There is limited evidence regarding the safety of topical tretinoin in pregnant humans.

Breastfeeding

It is not known whether tretinoin passes into human breast milk or if it could harm a nursing infant. Because many drugs are excreted in human milk, caution should be exercised. If you are breastfeeding or planning to breastfeed, consult your healthcare provider to discuss the potential risks and benefits of using either the oral or topical forms of this medication.

Topical use: FDA-approved for the treatment of acne vulgaris. Certain emollient cream formulations are also approved as adjunctive agents for the mitigation of fine wrinkles, mottled hyperpigmentation, and tactile roughness of facial skin.

Oral use: FDA-approved for the induction of remission in patients with acute promyelocytic leukemia (APL) who have a specific genetic mutation (the t(15;17) translocation and/or the presence of the PML/RARalpha gene).

Boxed Warnings

The oral form of tretinoin carries a boxed warning, the FDA's most serious type of warning, due to the risk of severe adverse reactions:

Retinoic Acid-APL Syndrome: Patients may experience a life-threatening syndrome characterized by fever, respiratory distress, and multi-organ failure.

Leukocytosis: There is a high risk of a very high white blood cell count during treatment.

Pregnancy Risk: Oral tretinoin is highly teratogenic and must not be used during pregnancy, as it can cause severe birth defects.

Prescription Status

Tretinoin is classified as a prescription-only medication (Rx). It is not available over-the-counter in the United States. Patients using the oral formulation are typically monitored closely in a hospital or specialized clinical setting due to the complexity of the treatment and the severity of potential side effects.

Question 12

What should I know about Tretinoin and acne?

Accepted Answer

How Tretinoin Works for Acne

Tretinoin belongs to a class of medications known as retinoids, which are derivatives of vitamin A. It functions by influencing the life cycle of cells, promoting the shedding of older cells and the development of new ones.

This medication works at a cellular level to modify how cells grow and regenerate. By altering these processes, it helps manage conditions by supporting the normal maturation and renewal of tissues.

This medication is effective against various types of acne, including:

Comedonal acne: Blackheads and whiteheads.

Inflammatory acne: Red bumps and pimples.

Treatment Expectations

It is common for acne to appear worse during the first few weeks of treatment. This occurs because the medication is working on pimples forming deep inside the skin. Improvement is usually seen within 2 to 3 weeks, but it may take more than 6 to 12 weeks of consistent use to see the full benefits.

Tretinoin is available in several topical formulations, including creams, gels, and lotions. The specific concentration and form prescribed depend on the severity of the acne and the patient's skin sensitivity.
