Where they actually differ
- They bill on different clocks. NextMeds charges every calendar month and WeightRx charges every 6 months. That alone changes what a “month” costs, which is the whole reason this index recomputes every price.
- One price holds and the other climbs. NextMeds’s price is the same at every dose; WeightRx’s is a starting-dose price that climbs. See what titration does to an advertised figure.
- What they advertise is not what they bill. WeightRx advertises $83 and bills $125.
