Looking After Your PICC Line — at Home

Only if your care team has trained you and given you the sterile supplies to do it. Dressing changes need specific materials — a sterile field, the right cleansing solution, and a film dressing designed for PICC lines. Doing it without these creates a real infection risk. If no nurse has been arranged to come to you, call your team and ask how your dressing changes are being organised rather than improvising at home.

Use the waterproof sleeve your team recommends, not a plastic bag secured with tape. Bags and tape do not create a reliable seal and water often gets in at the edges. The sleeve should cover the dressing and enough skin above and below it to form a proper seal. Your nurse should show you how to apply it before you go home. If you are unsure, ask before your first shower — not after.

Mild puffiness in the first day or two after the line is placed can be normal as the vein settles. Swelling that appears later, is getting worse, or spreads up toward the shoulder is not something to wait on — it can be a sign of a clot in the vein, which PICC lines can occasionally cause. Call your team the same day if the swelling is new or increasing. This is not a wait-and-see situation.

Yes, for most things — eating, writing, gentle movement. Avoid anything that puts sustained pressure on or around the line site: carrying heavy bags on that arm, vigorous repetitive exercise with that shoulder, or sleeping directly on it. Your team will tell you if there are restrictions specific to your situation, so confirm with them rather than guessing.

Do not try to push it back in — this is never safe. Cover the site loosely with clean gauze or a clean cloth and call your team immediately. If the line has come out completely and bleeding does not stop with firm pressure, go to the nearest emergency department. A line that has moved cannot be used until a nurse or doctor has confirmed its position.

Your team should give you an after-hours contact number before you go home with a PICC line. Keep it on your phone and written somewhere at home. If you do not have a number, ask before discharge. For fever, bleeding that does not stop, or sudden severe pain, go to the nearest emergency department rather than waiting for a callback. Most line complications are manageable when seen early.
