Vimpat side effects

Vimpat side effects, as per WebMD, may include nausea, blurred vision, vomiting, tiredness, a loss of balance, difficulty walking and/or memory problems.  These side effects tend to be most common when you first start the medication, according to the website, and may lessen as your body starts to adjust to the drug; however, all bodies will react differently, and your results will vary.  Always talk with your doctor if these effects persist or worsen.

Rarer side effects, according to WebMD, can include feeling depression, becoming suicidal and/or other related mental/mood problems.  Allergic reactions, also rare, can occur, causing fevers, swollen lymph nodes, itching, swelling, rashes and/or troubled breathing in extreme cases.  This is not a full list of side effects.  Always talk to your doctor about full disclosure.

The patent, at this time, does not expire until March of 2022, and until then, a generic cannot be available until the patent expires.  Even though this is when the patent expires, it does not mean a generic will readily be available as this will all depend on FDA approval and if any manufacturers decide to make a generic version.
