Can oral isotretinoin be taken continuously as a dietary supplement?

I rarely get acne.
I have been taking 20 mg of oral isotretinoin every three days for 13 months and would like to continue this regimen.
Is it okay to keep taking it? Also, does isotretinoin have to be taken with dinner, or can I take it with breakfast or lunch?

More Info

When it comes to the use of oral Vitamin A, particularly in the form of isotretinoin (commonly referred to as oral retinoids), it is essential to approach this treatment with caution and under the guidance of a healthcare professional. Isotretinoin is a powerful medication primarily used to treat severe acne, and while it can be effective for skin health, it also comes with potential side effects and risks that need to be carefully managed.

Long-Term Use of Oral Vitamin A
1. Duration of Use: Taking isotretinoin continuously for an extended period, such as 13 months, is not typical. Most treatment regimens last between 4 to 6 months, depending on the severity of the acne and the individual's response to the medication. Prolonged use can lead to increased risks of side effects, including dryness of the skin and mucous membranes, potential liver damage, and changes in lipid levels. Therefore, it's crucial to have regular follow-ups with your dermatologist to monitor your health and adjust the treatment as necessary.

2. Potential Side Effects: Long-term use of isotretinoin can lead to significant side effects. These may include:
- Dryness: This is the most common side effect, affecting the skin, lips, and eyes.

- Liver Function: Isotretinoin can affect liver enzymes, so regular blood tests are necessary to monitor liver function.

- Lipid Levels: It can also increase triglyceride levels, which can lead to cardiovascular issues if not monitored.

- Mood Changes: Some patients report mood swings or depression, which should be taken seriously.

3. Consultation with a Healthcare Provider: Before considering long-term use, it is essential to discuss your treatment plan with a dermatologist. They can provide guidance based on your specific skin condition, monitor for side effects, and determine whether continuing treatment is appropriate.

Timing of Administration
Regarding the timing of taking isotretinoin, it is generally recommended to take it with food to enhance absorption. While many patients take it with dinner, it can also be taken with breakfast or lunch as long as it is consumed with a meal. The key is to maintain consistency in how you take it, as this can help with absorption and effectiveness.

Conclusion
In summary, while oral Vitamin A (isotretinoin) can be beneficial for skin health, especially in treating acne, it is not advisable to take it continuously for extended periods without medical supervision. Regular consultations with your healthcare provider are crucial to ensure that the treatment remains safe and effective. Always follow their advice regarding dosage and timing to optimize the benefits while minimizing potential risks. If you have concerns about your skin health or the effects of isotretinoin, do not hesitate to reach out to your dermatologist for personalized guidance.
