Medically necessary liquids are allowed through a checkpoint in any amount once they have been screened. However, it is recommended that passengers limit the amount of liquid to what is reasonably necessary for his or her flight. Passengers should inform an officer if a liquid or gel is medically necessary and separate it from other belongings before screening begins.

Liquids, gels, and aerosols are screened by X-ray and medically necessary items in excess of 3.4 ounces will receive additional screening A passenger could be asked to open the liquid or gel for additional screening. TSA will not touch the liquid or gel during this process. If the passenger does not want a liquid, gel, or aerosol X-rayed or opened for additional screening, he or she should inform the officer before screening begins. Additional screening of the passenger and his or her property may be required, which may include a patdown.

Accessories required to keep medically necessary liquids, gels, and aerosols cool – such as freezer packs or frozen gel packs – are permitted through the screening checkpoint and may be subject to additional screening. These accessories are treated as liquids unless they are frozen solid at the checkpoint. If these accessories are partially frozen or slushy, they are subject to the same screening as other liquids and gels.

Supplies that are associated with medically necessary liquids and gels – such as IV bags, pumps and syringes – are allowed through a checkpoint once they have been screened by X-ray or inspection. The passenger should declare these items to an officer and separate them from other belongings for screening.
