Lamictal prescription medicine

Anyone considering the use of antiepileptic drugs must balance this risk of suicide with the clinical need for the drugs. Patients who are started on therapy should be closely observed for clinical worsening, suicidal thoughts , or unusual changes in behavior. Symptoms, Causes and Treatment What is the dosage for lamotrigine? The dose of immediate release lamotrigine for seizures in patients not taking valproic acid Depakote , Depakote ER, Depakene , Depacon , Stavzor , but taking seizure medications that reduce lamotrigine blood levels for example, phenobarbitol, phenytoin [ Dilantin , Dilantin ], carbamazepine [ Tegretol ], primidone is 50 mg once daily for two weeks, followed by mg daily given in two divided doses for two weeks.

Thereafter, the dose is increased by mg daily every weeks up to the usual maintenance dose of to mg daily given as a divided dose. When they were put on this drug for long term, severe episodes were controlled and there is evidence in support of this that is steadily increasing. Tests Before Lamotrigine Prescription A thorough evaluation is conducted before Lamotrigine is prescribed to the patient.

This includes urine tests and blood tests so that any medical conditions can be ruled out. For instance, thyroid disorders frequently lead to mood swings.

So, by conducting a medical examination in advance and ensuring that nothing else is interfering with physiology, it can be ensured that a mood disorder is not being exacerbated by Lamotrigine. Every few weeks, the dose is increased by the same amount, if needed.

For people who are specifically on Valproate, the starting dose is usually Doses can be bigger in case of Carbamazepine. The increasing doses are also bigger in this case.

With Tegretol Carbamazepine , enzymes facilitating Lamotrigine metabolism are induced. This evidence suggests, although it certainly does not prove, that the high SUDEP rates reflect population rates, not a drug effect.

This raises the possibility that lamotrigine may cause toxicity in these tissues after extended use. Although ophthalmological testing was performed in 1 controlled clinical trial, the testing was inadequate to exclude subtle effects or injury occurring after long-term exposure. Accordingly, although there are no specific recommendations for periodic ophthalmological monitoring, prescribers should be aware of the possibility of long-term ophthalmologic effects.

Laboratory Tests False-Positive Drug Test Results Lamotrigine has been reported to interfere with the assay used in some rapid urine drug screens, which can result in false-positive readings, particularly for phencyclidine PCP. A more specific analytical method should be used to confirm a positive result. Because of the possible pharmacokinetic interactions between lamotrigine and other drugs, including AEDs see Table 15 , monitoring of the plasma levels of lamotrigine and concomitant drugs may be indicated, particularly during dosage adjustments.

In general, clinical judgment should be exercised regarding monitoring of plasma levels of lamotrigine and other drugs and whether or not dosage adjustments are necessary. Isolated organ failure or isolated blood dyscrasias without evidence of multiorgan hypersensitivity may also occur.

Instruct them to be alert for the emergence or worsening of symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior or thoughts about self-harm. Instruct them to immediately report behaviors of concern to their physician.

Worsening of Seizures Advise patients to notify their physician if worsening of seizure control occurs. Pregnancy and Nursing Instruct patients to notify their physician if they become pregnant or intend to become pregnant during therapy and if they intend to breastfeed or are breastfeeding an infant. This registry is collecting information about the safety of antiepileptic drugs during pregnancy.

To enroll, patients can call the toll-free number [see Use In Specific Populations]. Inform patients who intend to breastfeed that LAMICTAL is present in breast milk and advise them to monitor their child for potential adverse effects of this drug. Discuss the benefits and risks of continuing breastfeeding.

Oral Contraceptive Use Instruct women to notify their physician if they plan to start or stop use of oral contraceptives or other female hormonal preparations. Also instruct women to promptly notify their physician if they experience adverse reactions or changes in menstrual pattern e.

Instruct them to notify their physician immediately if they develop signs and symptoms of meningitis such as headache, fever, nausea, vomiting, stiff neck, rash, abnormal sensitivity to light, myalgia, chills, confusion, or drowsiness while taking LAMICTAL.

Lamotrigine was negative in in vitro gene mutation Ames and mouse lymphoma tk assays and in clastogenicity in vitro human lymphocyte and in vivo rat bone marrow assays. Clinical trials excluded subtle effects and optimal duration of treatment.

There are no specific recommendations for periodic ophthalmological monitoring. Lamotrigine binds to the eye and melanin-containing tissues which can accumulate over time and may cause toxicity. Prescribers should be aware of the possibility of long-term ophthalmologic effects and base treatment on clinical response.

Patient compliance should be periodically reassessed with lab and medical testing of liver and kidney function to monitor progress or side effects. December — for use as monotherapy for treatment of partial seizures in adult patients when converting from a single enzyme-inducing anticonvulsant drug. January — for use as adjunctive therapy for partial seizures in pediatric patients as young as two years of age.

June — approved for maintenance treatment of Bipolar II disorder ; the first such medication since lithium. Lamotrigine, mg tablet. Seek emergency medical attention if you have: Do not stop taking Lamictal without first talking to your doctor, even if you feel fine.

You may have increased seizures if you stop using lamotrigine suddenly. Contact your doctor if your seizures get worse or you have them more often while taking this medicine. Taking this medication during early pregnancy can increase the risk of the baby being born with cleft lip or cleft palate.

Tell your doctor if you are pregnant or if you become pregnant during treatment. Before taking this medicine You should not take Lamictal if you are allergic to lamotrigine.

Lamictal may cause a severe or life-threatening skin rash, especially in children and in people who take too high a dose at the start of treatment. Serious skin rash may also be more likely to occur if you are taking lamotrigine together with valproic acid Depakene or divalproex Depakote. Tell your doctor if you have ever had: Some people have thoughts about suicide while taking this medicine. Your doctor will need to check your progress at regular visits.

Your family or other caregivers should also be alert to changes in your mood or symptoms. Do not start or stop taking seizure medication during pregnancy without your doctor's advice.
