can lamotrigine cause a false positive pregnancy test prevacid

In The Lancet Psychiatry, John R Geddes and colleagues1 reported on a randomised clinical trial assessing the antidepressant effects of lamotrigine added to quetiapine in patients with bipolar depression. Starting Lamotrigine Tablets in Women Taking Estrogen-Containing Oral Contraceptives: Although estrogen-containing oral contraceptives have been shown to increase the clearance of Lamotrigine [see Clinical Pharmacology (12.3)], no adjustments to the recommended dose-escalation guidelines for Lamotrigine tablets should be necessary solely based on the use of estrogen-containing oral contraceptives. There are many well-demonstrated causes of amphetamine false positives on both urine drug screens and the confirmatory GC/MS. Lamotrigine can be used to treat the following partial seizures, primary generalized tonic-clonic seizures, bipolar I disorder maintenance and Lennox-Gastaut syndrome. In vitro assessment of the inhibitory effect of Lamotrigine at OCT2 demonstrate that Lamotrigine, but not the N(2)-glucuronide metabolite, is an inhibitor of OCT2 at potentially clinically relevant concentrations, with IC 50 value of 53.8 mcM [see Drug Interactions (7)] . In a small subset of patients (n = 7) studied in a placebo-controlled trial, Lamotrigine had no effect on carbamazepine-epoxide plasma concentrations, but in a small, uncontrolled study (n = 9), carbamazepine-epoxide levels increased. A therapeutic plasma concentration range has not been established for Lamotrigine. Inform patients that multiorgan hypersensitivity reactions and acute multiorgan failure may occur with Lamotrigine. The occurrence of false-positives is mostly affected by the type of immunoassay used and the particular agent being tested. What are the possible side effects of Lamotrigine tablets? painful sores in your mouth or around your eyes. Chemical pregnancy. Data from several prospective pregnancy exposure registries and epidemiological studies of pregnant women have not detected an increased frequency of major congenital malformations or a consistent pattern of malformations among women exposed to Lamotrigine compared with the general population (see Data). Patients on rifampin and the protease inhibitor lopinavir/ritonavir should follow the same dosing titration/maintenance regimen used with antiepileptic drugs that induce glucuronidation and increase clearance [see Dosage and Administration (2.1), Drug Interactions (7), and Clinical Pharmacology (12.3)]. After oral administration of 240 mg of 14C-Lamotrigine (15 mcgCi) to 6 healthy volunteers, 94% was recovered in the urine and 2% was recovered in the feces. Prior to initiation of treatment with Lamotrigine tablets, the patient should be instructed that a rash or other signs or symptoms of hypersensitivity (e.g., fever, lymphadenopathy) may herald a serious medical event and that the patient should report any such occurrence to a healthcare provider immediately. The adverse reactions most commonly associated with discontinuation were rash (4.5%), headache (3.1%), and asthenia (2.4%). Human Data: Data from several international pregnancy registries have not shown an increased risk for malformations overall. b Drugs that induce Lamotrigine glucuronidation and increase clearance, other than the specified antiepileptic drugs, include estrogen-containing oral contraceptives rifampin, and the protease inhibitors lopinavir/ritonavir and atazanavir/ritonavir. Decreased Lamotrigine concentrations approximately 50%. Infrequent: Yawn. Patients could not be on more than 2 other anticonvulsants. Estrogen-containing oral contraceptives and other drugs, such as rifampin and protease inhibitors lopinavir/ritonavir and atazanavir/ritonavir, that induce Lamotrigine glucuronidation have also been shown to increase the apparent clearance of Lamotrigine [see Drug Interactions (7)]. There are no specific antidotes for Lamotrigine. Medication errors involving Lamotrigine tablets have occurred. Rare: Choreoathetosis, delirium, delusions, dysphoria, dystonia, extrapyramidal syndrome, faintness, grand mal convulsions, hemiplegia, hyperalgesia, hyperesthesia, hypokinesia, hypotonia, manic depression reaction, muscle spasm, neuralgia, neurosis, paralysis, peripheral neuritis. The subjects with severe hepatic impairment were without ascites (n = 2) or with ascites (n = 5). Infrequent: Abnormality of accommodation, conjunctivitis, dry eyes, ear pain, photophobia, taste perversion, tinnitus. Lamotrigine tablets 25 mg are available for oral administration as off white, round, flat faced, beveled edge tablets, debossed over score on one side and 60 on other side. Patients on rifampin and the protease inhibitor lopinavir/ritonavir should follow the same dosing titration/maintenance regimen used with antiepileptic drugs that induce glucuronidation and increase clearance [see Dosage and Administration (2.1), Drug Interactions (7), and Clinical Pharmacology (12.3)]. Lamotrigine tablets can cause serious side effects. Answer Lamictal ( lamotrigine) has been reported to cause false positives for PCP (phencyclidine) on urine drug screenings. The following serious adverse reactions are described in more detail in the Warnings and Precautions section of the labeling: Serious skin rashes [see Warnings and Precautions (5.1)], Hemophagocytic Lymphohistiocytosis [see Warnings and Precautions (5.2)], Multiorgan Hypersensitivity Reactions and Organ Failure [see Warnings and Precautions (5.3)], Cardiac Rhythm and Conduction Abnormalities [see Warnings and Precautions (5.4)], Blood Dyscrasias [see Warnings and Precautions (5.5)], Suicidal Behavior and Ideation [see Warnings and Precautions (5.6)], Aseptic Meningitis [see Warnings and Precautions (5.7)], Withdrawal Seizures [see Warnings and Precautions (5.10)], Status Epilepticus [see Warnings and Precautions (5.11)], Sudden Unexplained Death in Epilepsy [see Warnings and Precautions [see Warnings and Precautions (5.12)]. 2. Do not give Lamotrigine tablets to other people, even if they have the same symptoms you have. Generally, females receiving either Lamotrigine tablets as adjunctive therapy or placebo were more likely to report adverse reactions than males. It should be kept in mind that immediate-release Lamotrigine is rapidly absorbed [see Clinical Pharmacology (12.3)]. Safety and effectiveness of Lamotrigine tablets have not been established (1) as initial monotherapy; (2) for conversion to monotherapy from AEDs other than carbamazepine, phenytoin, phenobarbital, primidone, or valproate; or (3) for simultaneous conversion to monotherapy from 2 or more concomitant AEDs. In a study in healthy volunteers, daily doses of atazanavir/ritonavir (300 mg/100 mg) reduced the plasma AUC and C max of Lamotrigine (single 100-mg dose) by an average of 32% and 6%, respectively, and shortened the elimination half-lives by 27%. Based on a clinical pharmacology study in 24 subjects with mild, moderate, and severe liver impairment [see Clinical Pharmacology (12.3)] , the following general recommendations can be made. The adverse reactions that most commonly led to discontinuation of Lamotrigine tablets were rash (3%) and mania/hypomania/mixed mood adverse reactions (2%). Results of in vitro experiments suggest that Lamotrigine does not reduce the clearance of drugs eliminated predominantly by CYP2D6. Lamotrigine is contraindicated in patients who have demonstrated hypersensitivity (e.g., rash, angioedema, acute urticaria, extensive pruritus, mucosal ulceration) to the drug or its ingredients [see Boxed Warning, Warnings and Precautions (5.1, 5.3)]. Lamotrigine can also cause other types of allergic reactions or serious problems that may affect organs and other parts of your body like your liver or blood cells. If indicated, emesis should be induced; usual precautions should be taken to protect the airway. 25 mg, off white, round, flat faced, beveled edge tablets, debossed over score on one side and 60 on other side. Bipolar Disorder: In the controlled clinical trials, there was no increase in the incidence, type, or severity of adverse reactions following abrupt termination of Lamotrigine tablets. There are suggestions, yet to be proven, that the risk of rash may also be increased by (1) coadministration of Lamotrigine tablets with valproate (includes valproic acid and divalproex sodium), (2) exceeding the recommended initial dose of Lamotrigine tablets, or (3) exceeding the recommended dose escalation for Lamotrigine tablets. Call your doctor for medical advice about side effects. The effectiveness of Lamotrigine in the maintenance treatment of bipolar I disorder was established in 2 multicenter, double-blind, placebo-controlled trials in adult patients (aged 18 to 82 years) who met DSM-IV criteria for bipolar I disorder. Hemophagocytic lymphohistiocytosis (HLH) has occurred in pediatric and adult patients taking Lamotrigine for various indications. Lamotrigine is rapidly and completely absorbed after oral administration with negligible first-pass metabolism (absolute bioavailability is 98%). In a pooled analysis of data from 3 placebo-controlled clinical trials investigating adjunctive perampanel in patients with partial-onset and primary generalized tonic-clonic seizures, the highest perampanel dose evaluated (12 mg/day) increased Lamotrigine clearance by <10%. Storage: Store at 20C to 25C (68F to 77F); excursions permitted from 15C to 30C (59F to 86F) [see USP Controlled Room Temperature]. For dosing considerations for Lamotrigine tablets in patients on other drugs known to induce or inhibit glucuronidation, see Tables 1, 2, 5 to 6, and 13. The AUC and C max of olanzapine were similar following the addition of olanzapine (15 mg once daily) to Lamotrigine (200 mg once daily) in healthy male volunteers (n = 16) compared with the AUC and C max in healthy male volunteers receiving olanzapine alone (n = 16). What are the ingredients in Lamotrigine tablets? One proposed mechanism of action of Lamotrigine, the relevance of which remains to be established in humans, involves an effect on sodium channels. Commonly reported side effects of lamotrigine include: ataxia, skin rash, headache, insomnia, and nausea. Rather than triggering a false negative, they can sometimes return a . The presence of phencyclidine (PCP) is the most common false positive in people taking Lamictal, according to the drug's manufacturer . In patients with known heart problems, the use of Lamotrigine tablets may lead to a fast heart beat. Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. Starting these medicines may lessen how well Lamotrigine tablets works. Aciphex (rabeprazole sodium) - PPIs may test positive for THC. For that reason, we should really consider renaming it as the "egg-cellerator shot" or . lack of coordination dry mouth Infrequent: Dysphagia, eructation, gastritis, gingivitis, increased appetite, increased salivation, liver function tests abnormal, mouth ulceration. Increased Lamotrigine plasma levels could result in additional adverse reactions, such as dizziness, ataxia, and diplopia. Pooled analyses of 199 placebo-controlled clinical trials (monotherapy and adjunctive therapy) of 11 different AEDs showed that patients randomized to 1 of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% CI: 1.2, 2.7) of suicidal thinking or behavior compared with patients randomized to placebo. The primary endpoint was TIME (time to intervention for a mood episode or one that was emerging, time to discontinuation for either an adverse event that was judged to be related to bipolar disorder, or for lack of efficacy). b Carbamazepine, phenytoin, phenobarbital, and primidone have been shown to increase the apparent clearance of Lamotrigine. Lamotrigine did not displace other AEDs (carbamazepine, phenytoin, phenobarbital) from protein-binding sites. Controlled Monotherapy Trial in Adults with Partial-Onset Seizures: Table 10 lists adverse reactions that occurred in patients with epilepsy treated with monotherapy with Lamotrigine tablets in a double-blind trial following discontinuation of either concomitant carbamazepine or phenytoin not seen at an equivalent frequency in the control group.

Lamotrigine tablets can cause serious side effects. c The effect of other hormonal contraceptive preparations or hormone replacement therapy on the pharmacokinetics of Lamotrigine has not been systematically evaluated in clinical trials, although the effect may be similar to that seen with the ethinylestradiol/levonorgestrel combinations. Lamotrigine is the only mood stabilizer that calms mood swings by lifting the depression rather than suppressing the mania, says Dr. Aiken. Dosage adjustments may be necessary for women receiving estrogen-containing oral contraceptive preparations [see Dosage and Administration (2.1)]. Mania/Hypomania/Mixed Episodes: During the double-blind placebo-controlled clinical trials in bipolar I disorder in which adults were converted to monotherapy with Lamotrigine tablets (100 to 400 mg/day) from other psychotropic medications and followed for up to 18 months, the rates of manic or hypomanic or mixed mood episodes reported as adverse reactions were 5% for patients treated with Lamotrigine tablets (n = 227), 4% for patients treated with lithium (n = 166), and 7% for patients treated with placebo (n = 190). have had aseptic meningitis after taking Lamotrigine tablets or Lamotrigine extended-release tablets. This information should not take the place of medical care and advice from your healthcare provider. Hepatobiliary Tract and Pancreas Pancreatitis. Some of the patients treated with Lamotrigine who developed aseptic meningitis had underlying diagnoses of systemic lupus erythematosus or other autoimmune diseases. Weight-normalized Lamotrigine clearance was higher in those subjects weighing less than 30 kg compared with those weighing >30 kg. This evidence suggests, although it certainly does not prove, that the high SUDEP rates reflect population rates, not a drug effect. Frequent: Amblyopia. 1. No specific dosing guidelines can be provided for conversion to monotherapy with Lamotrigine tablets with AEDs other than carbamazepine, phenytoin, phenobarbital, primidone, or valproate.

Rare: Acute kidney failure, anorgasmia, breast abscess, breast neoplasm, creatinine increase, cystitis, dysuria, epididymitis, female lactation, kidney failure, kidney pain, nocturia, urinary retention, urinary urgency. Known Inducers or Inhibitors of Glucuronidation. Although benign rashes are also caused by Lamotrigine tablets, it is not possible to predict reliably which rashes will prove to be serious or life threatening. If it is almost time for your next dose, just skip the missed dose. Inform patients, their caregivers, and families that AEDs, including Lamotrigine tablets, may increase the risk of suicidal thoughts and behavior. Instruct them to immediately report behaviors of concern to their healthcare providers. In the clinical trials, doses up to 400 mg/day as monotherapy were evaluated; however, no additional benefit was seen at 400 mg/day compared with 200 mg/day [see Clinical Studies (14.2)]. In cases of HLH reported with Lamotrigine, patients have presented with signs of systemic inflammation (fever, rash, hepatosplenomegaly, and organ system dysfunction) and blood dyscrasias. This case will correlate lamotrigine (Lamictal) use with false-positive results for PCP on a rapid urine toxicology screen. A weight-based dosing guide for patients aged 2 to 12 years on concomitant valproate is provided in Table 3. Patients were dosed based on body weight and valproate use. Drop attacks were significantly reduced by Lamotrigine tablets (34%) compared with placebo (9%), as were tonic-clonic seizures (36% reduction versus 10% increase for Lamotrigine tablets and placebo, respectively). Human milk-feeding should be discontinued in infants with Lamotrigine toxicity. Patients with History of Allergy or Rash to Other Antiepileptic Drugs. take Lamotrigine tablets while taking valproate [DEPAKENE (valproic acid) or DEPAKOTE (divalproex sodium)]. take a higher starting dose of Lamotrigine tablets than your healthcare provider prescribed. Dosing recommendations for oral contraceptives and the protease inhibitor atazanavir/ritonavir can be found in General Dosing Considerations [see Dosage and Administration (2.1)]. Table 7. Distributed by: 200 mg, off white, round, flat faced, beveled edge tablets, debossed over score, 063 below score on one side and plain on other side. How can I watch for early symptoms of suicidal thoughts and actions. This disorder is variable in its expression, and other organ systems not noted here may be involved. Experience in patients with hepatic impairment is limited. In particular, the name Lamotrigine can be confused with the names of other commonly used medications. Treatment of acute manic or mixed episodes is not recommended. The commonly prescribed antidepressant, trazodone, has been reported to cause false positives in 3,4-methylenedioxymethamphetamine (MDMA) UDSs. To avoid an increased risk of rash, the recommended initial dose and subsequent dose escalations for Lamotrigine tablets should not be exceeded [see Boxed Warning]. Discuss the benefits and risks of continuing breastfeeding. Additional details of these drug interaction studies are provided in the Clinical Pharmacology section [see Clinical Pharmacology (12.3)]. For more information ask your healthcare provider or pharmacist. Generally, positive Lamotrigine side effects include diminished irritability, hyperactivity and perseveration, as well as improved energy and social function. All registered trademarks in this document are the property of their respective owners. Levofloxacin (Levaquin) and ofloxacin are the most likely of the quinolone antibiotics to cause a false positive urine test for opiates. If adverse reactions attributable to Lamotrigine tablets consistently occur during the pill-free week, dose adjustments to the overall maintenance dose may be necessary. What should I avoid while taking Lamotrigine tablets? Because valproate reduces the clearance of Lamotrigine, the dosage of Lamotrigine in the presence of valproate is less than half of that required in its absence [see Dosage and Administration (2.2, 2.3, 2.4), Drug Interactions (7)]. Proton pump inhibitors (PPIs) such as omeprazole, lansoprazole, dexlansoprazole, rabeprazole, pantoprazole, and esomeprazole can cause false negatives in the urea breath test and the stool antigen test. ethinylestradiol and 150 mcg levonorgestrel. Risk by Indication for Antiepileptic Drugs in the Pooled Analysis. Accordingly, Lamotrigine tablets should ordinarily be discontinued at the first sign of rash, unless the rash is clearly not drug related. Lamotrigine is used alone or with other medicines to treat seizures in patients two years and older. Epilepsy and many other illnesses for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. These tests can use either your pee or blood to look for HCG. Lamictal may cause false positives in urine drug tests. Immediately call your pharmacist if you receive a Lamotrigine tablet that does not look like one of the tablets shown below, as you may have received the wrong medication. Infectious adverse reactions included bronchiolitis, bronchitis, ear infection, eye infection, otitis externa, pharyngitis, urinary tract infection, and viral infection. One rash-related death was reported in a prospectively followed cohort of 1,983 pediatric patients (aged 2 to 16 years) with epilepsy taking Lamotrigine tablets as adjunctive therapy. You may get a false positive result when using at-home pregnancy tests. As with other AEDs, physiological changes during pregnancy may affect Lamotrigine concentrations and/or therapeutic effect. * Scar tissue. Rare: Goiter, hypothyroidism.
