What this guide is — and isn’t
This is the logistics guide: the fridge, the suitcase, the injection-day routine. It is not about whether a biologic is right for you, doses, or schedules — those belong entirely to you and your prescriber, and to the official instructions that come with your medicine.[1] When anything here differs from what your prescriber or the patient leaflet says, they win.
The fridge, and the 30 minutes before
- Biologic injections live in the refrigerator, in their carton, and shouldn’t be frozen or shaken.[1]
- Cold injections sting more. The widely given advice is to let the pen or syringe sit out and come toward room temperature before injecting — check your medicine’s leaflet for its exact guidance and timing.[1]
- Most biologics also tolerate a limited stretch at room temperature (the leaflet states how long, and it varies by product) — useful to know for a day out, but treat the leaflet’s number as the law.[1]
Injection day, kindly
- Rotate sites (thigh, abdomen; upper arm if someone else injects), and avoid injecting into skin that’s currently flaring, bruised, or scarred.[1]
- Some soreness or redness at the site is common; note it rather than worry it — it’s exactly the kind of thing worth having on one page at your next appointment.
- Missed or delayed dose? Don’t guess — the right answer depends on the medicine and the timing, so call your prescriber’s office or check the leaflet.[1]
Travelling with it
- Carry-on, never checked baggage — the hold can freeze, and bags go missing.
- A small insulated pouch with a cool pack covers most journeys; for long trips, plan the fridge at the other end.
- Medically necessary medicines are generally allowed through airport security beyond liquid limits — keep them in original packaging and be ready to say what they are.[3] (Ollowen’s travel card puts this in your pocket.)
- Crossing time zones on a fixed schedule? That’s a 30-second question for your prescriber before you leave.
Two things worth watching
Eyes: some people on dupilumab develop eye irritation or conjunctivitis; it’s usually manageable, but new eye redness, discomfort, or vision changes deserve a prompt call — and our eye-health guide covers the red flags.[2] Everything else new — new rashes, joint aches, anything that starts after starting the medicine — goes on the list for your next visit, dated. That dated list is exactly the evidence a busy appointment needs.
Injection dates, side notes, one page for your doctor
Ollowen keeps your injection and lab dates, your side-effect notes, and your questions in one place — and turns them into a one-page summary before each visit. For your doctor, not instead of one.
