Customs questions, X-ray machines, hotel fridges. The practical checklist for taking your pen abroad.

Documentation

Carry your latest prescription (printed) and a brief letter from your doctor stating diagnosis + medication. Most airports never ask; if they do, you're prepared in 10 seconds.

Carry-on, never checked

Cargo holds can freeze. Your pen rides in the cabin in an insulated pouch with a cold pack. Both TSA and Indian airport security allow medical cold packs.

Time-zone confusion

If your once-weekly day shifts (e.g. travel across 8 time zones), keep it on a fixed Indian-time anchor for the first week, then adjust by ±24 hours one cycle later. Don't double-dose to 'catch up'.

At your destination

Hotel fridges often run warmer than home fridges. If you're staying long, ask for the mini-bar (usually colder) or use a portable insulated travel case with replaceable ice packs.
