Dilantin® Infatabs for Seizure Control

These chewable phenytoin tablets help prevent and control epileptic seizures. You can review Dilantin Infatabs without insurance options and arrange US delivery from Canada. This page explains how it works, who it suits, and how to use it safely.

What Dilantin Is and How It Works

Dilantin® Infatabs are a chewable form of phenytoin, an antiseizure medicine that stabilizes overactive brain signals. By limiting repetitive firing of neurons, it can reduce the frequency of focal and generalized tonic-clonic seizures. The effect builds with steady use as levels reach a prescriber’s target range based on response and lab monitoring. YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

Dilantin Infatabs chewable are typically taken on a regular schedule, not as a rescue option. The treatment is often part of a broader care plan that may include lifestyle measures and, in some cases, other antiseizure therapies. Learn more about the condition in our overview of Seizures and our article Dilantin Uses.

Who It’s For

This medicine is used to help control focal (partial) seizures and generalized tonic-clonic seizures. It may be used for adults and children when a prescriber considers phenytoin appropriate. People with a history of severe skin reactions to anticonvulsants, significant liver issues, or known allergy to phenytoin or hydantoins should avoid it. Those of Asian ancestry may be tested for HLA-B*1502 before starting due to rare but serious skin reactions.

It is important to discuss your full medical history, including heart conditions, bone health, mental health, and potential pregnancy. The therapy can affect vitamin D and folate status, so your prescriber may monitor these over time. Caregivers and patients should also talk about safety planning for breakthrough events and driving rules where applicable.

Dosage and Usage

Follow your prescriber’s directions and the official label. Doses are individualized and may be adjusted based on response and blood levels. Chew each tablet thoroughly before swallowing. If preferred, the tablet may be swallowed whole with water if your prescriber agrees. Take this medicine at the same times each day to help keep levels steady.

Phenytoin can be taken with or without food, but consistency helps. Large changes in diet, especially very high protein or low carbohydrate patterns, can alter metabolism. Always check before starting or stopping supplements such as folic acid or calcium, as these may influence absorption or bone health plans. Do not stop suddenly unless told by your prescriber due to seizure risk.

Strengths and Forms

Infatabs chewable tablets are commonly available in 50 mg strength. Other phenytoin presentations include extended-release capsules and an oral suspension, which is often used for pediatric dosing. Availability may vary by jurisdiction and stock.

The oral suspension is frequently published at 125 mg per 5 mL. Your prescriber will choose the presentation that best supports accurate dosing and adherence. If your regimen changes, confirm the total daily dose and timing when moving between forms.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is nearly time for the next one. If it is close, skip the missed dose and resume your regular schedule. Do not double up. Set reminders on your phone or pillbox to maintain a steady routine. If you miss more than one dose, contact your prescriber for guidance.

Storage and Travel Basics

Store tablets in a tightly closed container, away from moisture and direct light. Keep out of reach of children and pets. Avoid storing in bathrooms where humidity fluctuates. When traveling, keep the medicine in your carry-on with the original label and a copy of your prescription. Pack extra tablets for unexpected delays and keep dosing times consistent across time zones when possible.

Benefits

This treatment can help reduce seizure frequency when taken as prescribed. Chewable tablets may be easier for certain patients who have difficulty swallowing standard capsules. The formulation supports flexible dosing strategies across age groups, guided by a prescriber. Consistent use may lessen disruptions to daily activities related to uncontrolled seizures.

Side Effects and Safety

• Common effects: dizziness, drowsiness, unsteady gait, nausea
• Vision changes: nystagmus or blurred vision
• Oral effects: gum overgrowth and tenderness
• Skin: mild rash or itching
• Coordination: tremor or slurred speech

Serious but less common risks include severe skin reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis, DRESS, liver problems, low blood counts, and mood or behavioral changes. Seek urgent care for widespread rash, fever, swollen glands, yellowing of skin or eyes, paleness with fatigue, or thoughts of self-harm. Alcohol may worsen side effects and seizure control.

Drug Interactions and Cautions

Phenytoin affects liver enzymes and can interact with many medicines. Notable interactions include certain antifungals, antiretrovirals, anticoagulants like warfarin, some antibiotics, antiarrhythmics, oral contraceptives, and other antiseizure medicines. St. John’s wort and heavy alcohol use can change levels. Always review new prescriptions and over-the-counter products with your healthcare professional before starting them.

Routine blood tests may be used to check levels, especially after changes to dose, other medicines, or diet. Let your prescriber know if you experience new neurologic symptoms such as increased unsteadiness, confusion, or slurred speech, which can signal levels that are too high. Report any rash right away.

What to Expect Over Time

Most people take this medicine long term for ongoing seizure management. Your prescriber may adjust the regimen based on seizure control, side effects, and lab results. It may take several visits to find a stable plan that suits your daily routine. Using a medication diary, aligning doses with daily habits, and scheduling lab checks can support steady control.

Compare With Alternatives

Other antiseizure options may be considered when appropriate. Two commonly used alternatives are Keppra® and Lamictal®. Your prescriber will decide based on seizure type, age, interactions, and tolerability. Switching requires careful planning, and overlap or gradual changes may be used to reduce risk.

Patient Suitability and Cost-Saving Tips

Good candidates can swallow or chew tablets reliably and can follow a consistent schedule. Those with significant liver disease, prior serious rash, or complex interaction risks require careful evaluation. Consider multi-month quantities if approved by your prescriber to reduce pharmacy visits. Set refill reminders so you do not run out.

If you take vitamins or minerals, discuss timing to avoid absorption changes. Keep a list of all medicines, including over-the-counter products, and bring it to appointments. Ask your prescriber if generic or different presentations could simplify dosing or improve adherence. If costs are a concern, price-compare among formulations or consider alternatives like Gabapentin when appropriate.
