Carry-on details
Allowed. Glucose tablets are a solid food item, so they have no quantity limit in carry-on and aren't part of the liquids rule at all. Glucose gel is allowed too — as a medically necessary supply for treating low blood sugar, it's exempt from the standard 3.4 oz / quart-bag limit, even in larger quantities. Declare glucose gel to the TSA officer at the checkpoint, separately from your quart-size liquids bag.
Checked-bag details
Allowed without restriction, in tablet or gel form. Carrying glucose tablets or gel in your carry-on is still smart, since you'll want fast access if your blood sugar drops during the flight.
Special instructions
Tablets don't need to be declared, but glucose gel should be declared at the checkpoint the same way as other medically necessary liquids and gels.
