include:
•
any sudden decrease in vision with or without eye pain and redness,

a blockage of fluid in the eye causing increased pressure in the eye
(secondary angle closure

new eye symptoms, including
any new problems with your vision.
Topiramate tablets may cause decreased sweating and increased body
temperature (fever). People,

and fever, especially in hot
temperatures. Some people may need to be hospitalized for this
condition. Call your healthcare provider
right away if you have a high fever, a fever that does not go away, or
decreased sweating.

(metabolic acidosis). If left untreated,
metabolic acidosis can cause brittle or soft bones (osteoporosis,
osteomalacia, osteopenia), kidney stones,

baby if you are pregnant. Metabolic
acidosis can happen with or without symptoms.

topiramate, at
pharmacologically relevant concentrations, blocks voltage-dependent
sodium channels, augments the
activity of the neurotransmitter gamma-aminobutyrate at some subtypes
of the GABA-A receptor,
