Unfortunately, several participants in the study had to discontinue treatment because of side effects such as excessive daytime sleepiness or orthostatic hypotension.
Other likely symptoms include convulsions, neuromuscular symptoms, shock, loss of consciousness, hypotension, ataxia, excessive salivation, limb paralysis, nausea and vomiting, fever, and severe abdominal pain.
Additionally, hypotension resulting from fetal distress or cesarean section births can lead to decreased blood and oxygen flow to the developing brain.
