Phenytoin, sold under the more commonly known brand name Dilantin, is one of the first anticonvulsant drugs that was founded in the early 20th century. It’s primarily used to prevent seizures, particularly tonic-clonic seizures that impact the entire brain or partial seizures that impact sections of the brain. Dilantin uses also include treating neuropathic pain and irregular heartbeat. In some cases, Dilantin may also be used for the treatment of mood disorders. Although it is not approved to use Dilantin for this purpose, there have been reported cases of this mislabeled use. Dilantin abuse, what is it?
Dilantin is one of the most prescribed drugs across the globe that has an off-white color and is typically fragrance-free. In 2016, there were about 2.7 million prescriptions of the drug in the U.S. Dilantin is typically taken orally or injected through the vein (intravenous), typically when a seizure last more than five minutes. Dilantin is often used as a second line of defense for seizures, but still plays an integral part for the treatment of status epilepticus, seizures following a surgery or seizures that occur in a medical facility.
How Should You Take Dilantin?
Like all prescriptions, it’s important to use Dilantin as prescribed by your doctor. Do not change your Dilantin dosage unless told by your doctor. Here are common guidelines when it comes to taking Dilantin:
When taking an extended-release capsule, make sure to swallow it whole. Do not chew, break, crush or open the drug.
Dilantin Infatabs chewable is not for once-per-day dosage. Users must take them two or three times per day depending on your doctor’s instructions.
Shake the liquid version of Dilantin before you measure a dose. It’s important not to use a spoon. Use a dosing syringe or a medicine dose-measuring device.
If your prescription does not seem to keep your seizures under control, it’s important to tell your doctor immediately, but do not stop using Dilantin. Seizures can occur if you suddenly stop using the drug.
If you miss a dose, take it as soon as possible unless it’s almost time for your next dose. Skip the missed dose and continue with your regular cadence. Do not double the doses.

Dilantin Abuse And Overdose
Like many prescription drugs, Dilantin abuse can occur for both patients and non-patients. In most cases of abuse, the user is trying to achieve a Dilantin high. Often at times, users abuse Dilantin in conjunction with other substances, most commonly alcohol. Ironically, the drug label for Dilantin clearly indicates that the drug should not be taken with alcohol because it will decrease the effectiveness of the drug and increase unwanted side effects.
However, Dilantin is not a major drug for abuse when looking at the bigger picture. Using Dilantin does not produce significant euphoria even though it may be used to regulate pain. Despite needing a prescription, the drug is not labeled as a controlled substance by the United States Drug Enforcement Administration. Dilantin should only be used under the supervision of your doctor due to the harmful side effects.
Although Dilantin is not a major drug of abuse, Dilantin toxicity can occur and can lead to death. Overdose symptoms may include:
Loss of balance
Muscle stiffness or weakness
Slow or shallow breathing
Twitching eye movements
Dilantin toxicity is rarely fatal, but can cause neurologic after effects such as nystagmus, ataxia and a coma. If you or someone experiences overdosing and has serious symptoms such as passing out or trouble to breathe, immediately call 911. In other cases, call a poison control center right away. People in the U.S. can call 1-800-222-1222 to reach their local poison control center.
