Lacosamide is a medication used to treat partial-onset seizures, a type of epilepsy. According to the drug's prescribing information, there is no specific mention of lacosamide causing sudden changes in blood pressure [1]. However, it is important to note that all medications can have side effects that are not specifically listed in the prescribing information.

Common side effects of lacosamide include dizziness, headache, and double vision [1]. These side effects can potentially lead to falls or accidents, which could result in changes in blood pressure. It is also possible that lacosamide could interact with other medications that a person is taking, leading to changes in blood pressure [1].

It is always important for individuals to discuss any concerns about medication side effects or potential interactions with their healthcare provider. Healthcare providers can provide personalized advice based on a person's medical history and current medications.

In summary, while there is no specific mention of lacosamide causing sudden changes in blood pressure in the prescribing information, it is possible that the medication could indirectly lead to changes in blood pressure through side effects or interactions with other medications.
