  In axion monodromy inflation, traversing $N$ axion periods corresponds to
discharging $N$ units of a quantized charge. In certain models with moving
D7-branes, such as Higgs-otic inflation, this monodromy charge is D3-brane
charge induced on the D7-branes. The stress-energy of the induced charge
affects the internal space, changing the inflaton potential and potentially
limiting the field range. We compute the backreaction of induced D3-brane
charge in Higgs-otic inflation. The effect on the nonperturbative
superpotential is dramatic even for $N=1$, and may preclude large-field
inflation in this model in the absence of a mechanism to control the
backreaction.
