Bring a letter from your doctor explaining your condition, along with a list of your medications and their generic names. This document — sometimes called a "psoriasis passport" — can make travel easier if you need to explain your condition or replace a medication.

Keep a digital copy on your phone in case the original is lost.

If storage requirements allow, consider bringing an extra dose of medication with you. Anything you don't want lost or damaged should stay with you in your carry-on rather than in checked luggage. For U.S. airport security, medically necessary liquid medications and creams can exceed the usual 3.4-ounce (100-milliliter) carry-on limit.

If you use injectable medication, pack a travel-size sharps disposal container along with supplies such as alcohol wipes and bandages.

Creating a travel box with your medications ahead of time can help you stay on track even when travel disrupts your usual routine.

If your medication needs refrigeration, plan for reliable access to a refrigerator or use a temperature-stable storage option. There are several options to keep medications cool while traveling, from water-activated cooling wallets to portable refrigeration devices.

Bring the moisturizers, cleansers, and other skin care products you regularly use at home. Travel-size containers can make packing easier and help you avoid switching to unfamiliar products that may irritate your skin.

Sunscreen is worth keeping as a standing item in your travel bag year-round. In cold or dry climates, rich emollients such as creams or ointments can help keep skin moisturized. Because cold, dry weather can trigger psoriasis flares, bring products suited to the climate at your destination.

Since stress is a known trigger for psoriasis flares, it helps to build in buffer time between flights or activities and avoid an overly packed itinerary.

Consider packing a small "calm kit" with items like noise-canceling headphones or an eye mask. Leave time for your usual medication and skin care routines.

Some vaccines may require additional planning if you take a biologic medication. If you need vaccines before traveling, talk with your healthcare team well in advance. They can explain which vaccines are appropriate and how your treatment may affect vaccine timing.
