Dilantin® (phenytoin) Infatabs 50 mg chewable tablets for seizures

What Dilantin® Is and How It Works

Dilantin® Infatabs are chewable phenytoin tablets used to prevent and control seizures. Each tablet contains 50 mg of phenytoin for flexible dosing. Many people choose dilantin infatabs 50 mg when titration is needed. If paying cash, phenytoin 50 mg infatab without insurance can be more affordable through Canadian pricing at YouDrugstore.

Phenytoin is a hydantoin anticonvulsant. It limits repetitive firing of neurons by stabilizing voltage-gated sodium channels. Clinicians use it for focal (partial) seizures and generalized tonic-clonic seizures. It is not effective for absence seizures. Dilantin® Infatabs are taken by mouth and are easy to chew or swallow with water.

Dosage and Usage

Phenytoin dosing is individualized and guided by clinical response and blood levels. Follow your prescriber’s instructions. Do not change your dose unless your prescriber directs it.

• Chew Dilantin® Infatabs thoroughly or swallow with water.
• Dosing is often divided two to three times daily with the chewable tablets.
• Clinicians may start with small doses and increase by 25–50 mg steps.
• Blood tests may guide dosing; many aim for 10–20 mcg/mL total phenytoin.
• Take doses at the same times each day for steady levels.
• Avoid taking at the same time as antacids or calcium; separate by a few hours.
• If you miss a dose, take it when remembered unless it is near the next dose. Skip the missed dose if close to the next scheduled time. Do not double up.
• Do not stop phenytoin suddenly; sudden changes can increase seizure risk.

Storage and travel:

• Store at 20–25°C (68–77°F) in a dry place.
• Keep the bottle tightly closed and protect from moisture.
• Do not store in a bathroom.
• Keep out of reach of children and pets.
• When you travel, keep tablets in the original labeled container.
• Carry your prescription details and pack extra for delays.

Benefits and Savings

Dilantin® helps reduce seizure frequency and severity when dosed and monitored correctly. The 50 mg Infatabs support precise adjustments, which is useful in pediatrics and in adults who need small dose changes. The chewable format can be easier for those who have trouble swallowing.

Ordering from YouDrugstore can offer 60–80% savings compared with typical US prices. Many patients paying without insurance find Canadian pricing predictable and budget-friendly. You can choose brand or other formats used in similar care plans, based on your prescription.

Side Effects and Safety

Not everyone experiences side effects, and many are mild and temporary. Contact a clinician if anything concerns you.

• Common: drowsiness, dizziness, headache, nausea, vomiting, constipation.
• Neurologic: unsteady gait, nystagmus, slurred speech, tremor.
• Dental: gingival overgrowth; good oral hygiene helps reduce risk.
• Skin: mild rash or itching.
• Metabolic/bone: low vitamin D over time, possible osteopenia.
• Serious (seek urgent care): severe skin reaction (SJS/TEN), DRESS, fever, mouth sores, yellowing skin/eyes, unusual bleeding, severe fatigue, mood changes or suicidal thoughts.
• Interactions: phenytoin induces liver enzymes and can reduce the effect of many medicines, including hormonal contraceptives, some anticoagulants, antifungals, and antivirals. Alcohol can add to sedation. Always have your full medication list reviewed.
• Pregnancy: phenytoin can harm an unborn baby; folate may be advised. Discuss family planning and contraception with a clinician.

Onset Time

Phenytoin levels rise over several doses. Many patients reach steady-state in about 7–10 days, though timing varies due to non-linear metabolism. Some benefit can appear once therapeutic levels are reached. Ongoing monitoring helps fine-tune dosing for stable control.

Compare With Alternatives

Different phenytoin forms fit different needs. Extended-release capsules can allow less frequent dosing once stable. If you prefer capsules, see Dilantin®. For those who need a liquid form or use feeding tubes, prescribers may choose Dilantin® Suspension.

Other antiepileptics, such as levetiracetam, lamotrigine, or valproate, may be used instead of or with phenytoin based on seizure type, age, and comorbidities. Gabapentin (brand Neurontin®) is an option for neuropathic pain and as adjunctive therapy in some seizure plans, but it serves different roles and has a different interaction profile.

Combination Therapy

Phenytoin is often part of a broader seizure management plan. Clinicians may add or taper other antiepileptics to balance efficacy and tolerability. Because phenytoin induces enzymes, they monitor for reduced effectiveness of other drugs, including hormonal contraceptives. Nonhormonal contraception may be considered. Supplements such as folate and vitamin D are sometimes used if a clinician advises them. Never start or stop medicines or supplements without clinical guidance.

Patient Suitability and Cost-Saving Tips

Dilantin® Infatabs may suit patients who need small dose steps or a chewable format. It is used for focal and generalized tonic-clonic seizures. It is not a first choice for absence seizures. Caution is needed with liver disease, low albumin, bone disorders, or a prior severe rash to aromatic anticonvulsants. Genetic factors (such as HLA-B*1502 in some Asian populations) can raise serious skin reaction risk; clinicians may screen when appropriate.

You can increase value with practical steps. Ask your prescriber whether a multi-month supply is appropriate; longer supplies can lower the per-month cost. Turn on reorder reminders so you do not run out. If you are exploring deals, see one place for current offers and bulk options.
