Dilantin

Dilantin is a popular type of anticonvulsant drug. It is often prescribed to people who regularly suffer from seizures, or patients who have recently undergone brain surgery or surgery on their nervous system. Dilantin comes in several forms, including extended-release capsules, chewable tablets, and liquid.

What is Dilantin?

Dilantin is an anticonvulsant and an anti-epileptic drug available in the US by prescription. It may also be used off-label in order to control irregular heartbeats. Back in the 1970’s, there was a push to also use Dilantin as an antidepressant, but due to financial concerns and a lack of clinical evidence, it was never approved for such use.

Dilantin Benefits

Over its many centuries in use, Dilantin has been taken to resolve a number of conditions and disorders, including:

  • Reducing the risk of epileptic seizures by limiting electrical activity in the brain
  • Reducing the risk of seizure in patients who have recently undergone brain surgery
  • Controlling irregular heartbeats

*All individuals are unique. Your results can and will vary.

Dilantin Side Effects

Dilantin has many serious side effects and should only be taken under close medical supervision. It can reduce motor skills and dull reflexes, so try to avoid driving or operating heavy machinery until you know how it will affect you.

Like many antidepressants, there is a risk of developing mood disorders and suicidal thoughts. Get in touch with your doctor immediately if you experience any of these symptoms. Because Dilantin is contraindicated for many other different drugs, including antidepressants, blood thinners, antacids, herbal supplements, and some vitamins, be sure to mention any and all other medications you are currently taking.

Dilantin can make the birth control pill less effective, so be sure to have a backup form of contraception. Other side effects include headache, nausea, vomiting, constipation, dizziness, drowsiness, trouble sleeping, nervousness, and swollen/bleeding gums.

*All individuals are unique. Your results can and will vary.

How Does Dilantin Help Brain Function?

Dilantin helps people who suffer from chronic seizures by reducing the amount of electrical activity in the brain that’s responsible for most seizures.

    Editor's Choice
    Constant Focus

    A kitchen-sink herbal focus supplement combining many cognitive-support botanicals and nutrients. Some individual ingredients (Bacopa, huperzine A) have supporting data, but the proprietary blend itself is not clinically validated.

    Focus Factor

    One of America's best-known brain supplements for ~20 years. Essentially a multivitamin blended with common nootropic add-ins (DMAE, bacopa, ginkgo, phosphatidylserine). Popular and inexpensive, but the cognitive ingredients are under-dosed and clinical evidence for measurable benefit is thin.

    HGH Factor

    An oral 'HGH releaser' built on amino acids (arginine, glutamine, ornithine) claimed to prompt natural growth-hormone production as a safer alternative to injections. Evidence is weak: amino-acid secretagogues need very high doses to affect HGH, and no rigorous data support this product's claims.

    Neuro Clarity

    An inexpensive OTC herbal-and-amino-acid nootropic blend built around St. John's Wort, DMAE and botanical extracts. Affordable and widely sold, but relies on a modest proprietary blend with limited clinical backing at the doses used. St. John's Wort also carries notable drug-interaction risk.

    A prescription central-nervous-system stimulant of mixed amphetamine salts approved for ADHD and narcolepsy. Strongly evidence-backed for its indications but carries abuse, dependence and cardiovascular risks; not a supplement.
