Acitretin and Fish Oil, a synergy.

Acitretin can raise triglycerides, and fish oil may help reduce retinoid-associated hypertriglyceridemia. Direct evidence is strongest for isotretinoin and etretinate, while acitretin is closely related to etretinate and is monitored for the same lipid problem. This is adjunctive lipid support and should not replace dose adjustment or prescription lipid therapy when triglycerides are high.

Synergy

What is happening. Acitretin can raise triglycerides, and fish oil may help reduce retinoid-associated hypertriglyceridemia. Direct evidence is strongest for isotretinoin and etretinate, while acitretin is closely related to etretinate and is monitored for the same lipid problem. This is adjunctive lipid support and should not replace dose adjustment or prescription lipid therapy when triglycerides are high.

Mechanism. Marine omega-3 fatty acids reduce hepatic VLDL triglyceride production and improve triglyceride clearance. This can counter the triglyceride elevations seen with systemic retinoids, including aromatic retinoids related to acitretin.

Recommendation. Fish oil is a reasonable option to discuss if triglycerides rise on acitretin. Continue fasting lipid monitoring and follow your dermatologist's plan for dose changes if levels become unsafe. Avoid very high fish oil doses if you have bleeding risk or take anticoagulants.
