Acitretin is a powerful oral retinoid medication, a derivative of Vitamin A, primarily used to treat severe psoriasis and other skin disorders. While it can be highly effective, its use comes with significant dietary considerations, especially regarding alcohol and supplemental Vitamin A. Understanding these restrictions is paramount for patient safety and treatment efficacy.
The Critical Warning: Avoid All Alcohol
The most critical and non-negotiable dietary restriction when taking acitretin is the complete avoidance of alcohol, and this warning extends beyond beverages to any food or medication containing alcohol. For women of childbearing potential, this rule is particularly strict and must be followed not only during treatment but also for at least two months after stopping the medication.
The reason for this strict prohibition is that consuming alcohol while on acitretin can metabolize the drug into a compound called etretinate. Etretinate is a teratogen, a substance known to cause severe birth defects. Crucially, etretinate has a much longer half-life than acitretin, meaning it can linger in the body for over three years. This drastically extends the period during which pregnancy poses a high risk of birth defects. For this reason, women are advised to continue effective contraception for at least three years after their last dose of acitretin.
Beyond the teratogenic risk, alcohol consumption can also exacerbate some of acitretin's side effects. Both acitretin and alcohol can affect liver function, so their combined use significantly increases the risk of liver inflammation and potential damage. Alcohol can also contribute to elevated blood fat levels, another side effect associated with acitretin.
Avoid Dietary Supplements Containing Vitamin A
Since acitretin is a retinoid, an artificial form of Vitamin A, taking additional Vitamin A supplements is unnecessary and dangerous. Excessive Vitamin A can lead to a condition known as hypervitaminosis A, which can cause or worsen many of acitretin's side effects, such as peeling skin, hair loss, vision problems, and liver toxicity.
Patients should check the labels of all dietary supplements, multivitamins, and herbal products to ensure they do not contain Vitamin A. Any questions about supplements should be directed to a healthcare provider or pharmacist before starting treatment.
Acitretin and General Food Guidelines
Unlike some medications, acitretin does not have specific restrictions on most foods, but how you take it in relation to food is important. Acitretin should always be taken with food, preferably your main meal of the day. Taking the medication with a fatty meal or a glass of milk can improve its absorption into the body, ensuring you receive the full therapeutic effect.
While no specific foods beyond those containing alcohol or supplemental Vitamin A are prohibited, a healthy diet is beneficial for managing conditions like psoriasis. A diet rich in fruits, vegetables, and whole grains can help manage the inflammation associated with psoriasis flare-ups. It's also important to stay hydrated by drinking plenty of water, especially since acitretin can cause dry skin and lips.
Food Considerations: What to Avoid vs. What to Include
This table provides a quick reference for making informed dietary choices while on acitretin.
| Category | Items to Strictly Avoid | Items to Include |
|---|---|---|
| Alcohol | Beer, wine, liquor, cocktails, alcohol-containing sauces, and certain medications (check labels) | N/A |
| Supplements | All supplements containing Vitamin A or retinoids (e.g., multivitamin with >2500 IU Vitamin A) | Doctor-approved supplements, non-retinoid vitamins |
| Meals | Taking acitretin on an empty stomach | Taking acitretin with a fatty meal for better absorption |
| Overall Diet | Excessive rich or spicy foods (may upset stomach) | A balanced diet with fruits, vegetables, lean protein, and whole grains |
| Drinks | Alcohol | Water, milk, and other non-alcoholic beverages |
Conclusion
Navigating your diet while on acitretin involves a few, but very important, rules. The most critical is the complete avoidance of alcohol, especially for women of childbearing potential, to prevent the formation of etretinate, a teratogen with a long half-life. The second is to abstain from all dietary supplements and multivitamins that contain supplemental Vitamin A to prevent additive retinoid side effects. Outside of these specific restrictions, maintaining a balanced, healthy diet and taking your medication with food will help maximize its effectiveness while minimizing unwanted side effects. Always consult your healthcare provider with any specific dietary concerns or questions about medications or supplements. An open and honest discussion with your medical team is your best tool for a safe and successful treatment journey.
