Acitretin Medications

Acitretin Info

What is Acitretin?

Acitretin is a synthetic retinoid - a medication that is chemically related to vitamin A. It is used mainly to manage certain skin disorders by helping skin cells grow and shed at a more normal rate. Acitretin is the active ingredient in several products, the most well-known being Soriatane.

Medications with Acitretin

In Hong Kong, the primary product that contains acitretin is Soriatane tablets, supplied in strengths such as 10 mg, 20 mg and 30 mg. Some pharmacies may also stock generic versions of acitretin, which are marketed simply as “acitretin tablets.” The tablets are taken orally; other formulations (e.g., creams or gels) are not currently available in the local market.

What Does Acitretin Treat?

• Plaque psoriasis - a chronic condition where skin cells build up quickly, forming thick, scaly patches.
• Severe pustular psoriasis - a rarer form that produces pus-filled lesions and can be painful.
• Erythrodermic psoriasis - an extensive form that causes widespread redness and skin shedding.
• Other keratinisation disorders - conditions where the skin’s outer layer becomes overly thick or rough, such as certain types of ichthyosis.

Acitretin works best for patients whose disease has not responded adequately to topical treatments or lighter-weight systemic drugs. Its ability to normalise skin cell turnover makes it a valuable option for these challenging cases.

How Acitretin Works

Acitretin influences the way skin cells mature and separate, encouraging a more regular shedding process. By slowing the rapid production of new cells, the medication reduces the thickness of plaques and helps the skin look smoother. Effects usually become noticeable after a few weeks of regular use, though the exact timeline can differ between individuals.

Safety Information

Common Side Effects

• Dry, peeling skin - especially on the hands, feet and lips.
• Mild itching or a feeling of tightness.
• Temporary increase in triglyceride (fat) levels in the blood.
• Small changes in liver-function test results, often without symptoms.

These reactions are usually mild and tend to improve with continued treatment or simple supportive care, such as moisturizing the skin.

Serious Reactions

• Severe allergic responses that may involve swelling of the face, throat or tongue, or difficulty breathing.
• Sudden, intense itching with a rash that spreads quickly.
• Marked elevation of liver enzymes or blood lipids that could pose health risks.

If any of these signs appear, seeking immediate medical attention is advised.

Who Should Be Cautious

• Pregnant individuals - acitretin is known to cause birth defects, and its effects can persist for up to three years after stopping the drug. Effective contraception is required before, during, and for a substantial period after treatment.
• People with a history of liver disease, high cholesterol or severe hypertriglyceridaemia should discuss their health background with a clinician before starting acitretin.
• Individuals who are allergic to retinoids or any component of the tablet formulation should avoid the medication.

Interaction Awareness

Acitretin can interact with several drug groups, including:

• Systemic retinoids - using more than one retinoid at the same time can raise toxicity risk.
• Alcohol - may increase the chance of liver-related side effects.
• Certain antibiotics and anti-seizure medicines - can affect how acitretin is processed in the body.

Patients should also be aware that acitretin may make the skin more sensitive to sunlight, so protective clothing and sunscreen are prudent when outdoors. Detailed interaction lists are provided on each specific medication’s information sheet.

What to Know Before Using

Store acitretin tablets in a dry place, away from direct heat and moisture. Keep them out of reach of children. Treatment duration varies: some people use acitretin for a few months to control an acute flare, while others may need longer courses for chronic disease control. Always follow the guidance printed with your specific product and the advice of a qualified health professional.
