If you know what insurance she’d be on, check that the exact meds (including dosage and formulation) are on the insurance plan’s formulary. Otherwise, despite the prescription and FSA approval she risks not being able to get her med without paying full sticker price.
She also needs to know whether the plan would exclude any of her diagnoses from coverage. Meds prescribed to treat it would also not be covered.
US Kotex and Always come in several different lengths and thicknesses. They are sold both with and without wings. If you’re getting pads that are bulkier than you prefer, it’s because you’re accidentally choosing that configuration. The overnight ones are almost twice as long as the lights, and at least as thick as a nappy. Whereas ultrathins are as slim as a pantiliner; no one could confuse them with a nappy.
