Focalin also contains the following inert ingredients: pregelatinized starch, lactose monohydrate, sodium starch glycolate, microcrystalline cellulose, magnesium stearate, and FD&C Blue No.1 #5516 aluminum lake (2.5 mg tablets), D&C Yellow Lake #10 (5 mg tablets); the 10 mg tablet contains no dye.

USES

This medication is used to treat attention deficit hyperactivity disorder – ADHD. It works by changing the amounts of certain natural substances in the brain. Dexmethylphenidate belongs to a class of drugs known as stimulants. It can help increase your ability to pay attention, stay focused on an activity, and control behavior problems. It may also help you to organize your tasks and improve listening skills.

How to use Focalin

Read the Medication Guide provided by your pharmacist before you start taking dexmethylphenidate and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually twice a day with or without food. Take the first dose as soon as you wake up in the morning and the second dose at least 4 hours later, or take as directed by your doctor. Taking this medication late in the day may cause trouble sleeping (insomnia).

The dosage is based on your medical condition and response to treatment. Your doctor may direct you to gradually increase or decrease your dose. Also, if you have used it for a long time, do not suddenly stop using this drug without consulting your doctor. The total daily dose is usually 20 milligrams or less. Carefully follow your doctor’s instructions.

Methylphenidate and dexmethylphenidate are different medications and do not provide the same amount of medicine. Do not switch between products unless your doctor tells you to

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.

This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as depression, suicidal thoughts, or other mental/mood changes) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions right away.

When this medication is used for a long time, it may not work as well. Talk to your doctor if this medication stops working well.

Though it helps many people, this medication may sometimes cause addiction. This risk may be higher if you have a substance use disorder (such as overuse of or addiction to drugs/alcohol). Take this medication exactly as prescribed to lower the risk of addiction. Ask your doctor or pharmacist for more details.

Tell your doctor if your condition does not improve or if it worsens.

INTERACTIONS

Methylphenidate may inhibit the metabolism of coumarin anticoagulants, certain anticonvulsants, and some antidepressants (tricyclic antidepressants and selective serotonin reuptake inhibitors). Concomitant administration may require dose adjustments, possibly assisted by monitoring of plasma drug concentrations.There are several case reports of methylphenidate inducing serotonin syndrome with concomitant administration of antidepressants.

When methylphenidate is coingested with ethanol, a metabolite called ethylphenidate is formed via hepatic transesterification,[42][43] not unlike the hepatic formation of cocaethylene from cocaine and alcohol. The reduced potency of ethylphenidate and its minor formation means it does not contribute to the pharmacological profile at therapeutic doses and even in overdose cases ethylphenidate concentrations remain negligible.

Coingestion of alcohol (ethanol) also increases the blood plasma levels of d-methylphenidate by up to 40%.

Liver toxicity from methylphenidate is extremely rare, but limited evidence suggests that intake of β-adrenergic agonists withmethylphenidate may increase the risk of liver toxicity.

DOSAGE

Your dose of Focalin will depend on your age, weight, and medical condition.

Your doctor will probably start you on a lower dose of this medicine and gradually increase it.

The total daily dosage is typically 20 milligrams (mg) for immediate release or less, and 40 mg or less if you’re taking extended release Focalin.

Focalin comes as a tablet or an extended-release capsule to take by mouth.

The tablet is typically taken twice a day with or without food.

The extended-release capsule is usually taken once a day with or without food.

Try not to take Focalin at night, as it may cause insomnia.

Don’t crush or chew the extended-release capsules. Swallow them whole.

However, if you can’t swallow them, you can put the contents on a spoonful of applesauce and swallow the mixture right away.

You should follow the information on your prescription label carefully. Don’t take more or less of this medication than is prescribed.

Focalin Overdose

If you suspect an overdose, you should contact a poison control center or emergency room immediately.

Missed Dose of Focalin

If you miss a dose of Focalin, take it as soon as you remember.

However, if it’s almost time for your next dose, skip the missed dose and continue on your regular dosing schedule.

Don’t take extra medicine to make up for a missed dose

PRECAUTIONS

Hematologic Monitoring

Periodic CBC, differential, and platelet counts are advised during prolonged therapy.

Information For Patients

Prescribers or other health professionals should inform patients, their families, and their caregivers about the benefits and risks associated with treatment with dexmethylphenidate and should counsel them in its appropriate use. A patient Medication Guide is available for Focalin. The prescriber or health professional should instruct patients, their families, and their caregivers to read the Medication Guide and should assist them in understanding its contents. Patients should be given the opportunity to discuss the contents of the Medication Guide and to obtain answers to any questions they may have. The complete text of the Medication Guide is reprinted at the end of this document.

Priapism

Advise patients, caregivers, and family members of the possibility of painful or prolonged penile erections (priapism). Instruct the patient to seek immediate medical attention in the event of priapism.

Circulation problems in fingers and toes [Peripheral vasculopathy, including Raynaud’s phenomenon]:

Instruct patients beginning treatment with Focalin about the risk of peripheral vasculopathy, including Raynaud’s phenomenon, and in associated signs and symptoms: fingers or toes may feel numb, cool, painful, and/or may change color from pale, to blue, to red.

Instruct patients to report to their physician any new numbness, pain, skin color change, or sensitivity to temperature in fingers or toes.

Instruct patients to call their physician immediately with any signs of unexplained wounds appearing on fingers or toes while taking Focalin.

Further clinical evaluation (e.g., rheumatology referral) may be appropriate for certain patients.

Carcinogenesis, Mutagenesis, And Impairment Of Fertility

Lifetime carcinogenicity studies have not been carried out with dexmethylphenidate. In a lifetime carcinogenicity study carried out in B6C3F1 mice, racemic methylphenidate caused an increase in hepatocellular adenomas, and in males only, an increase in hepatoblastomas at a daily dose of approximately 60 mg/kg/day. Hepatoblastoma is a relatively rare rodent malignant tumor type. There was no increase in total malignant hepatic tumors. The mouse strain used is sensitive to the development of hepatic tumors, and the significance of these results to humans is unknown.

Racemic methylphenidate did not cause any increase in tumors in a lifetime carcinogenicity study carried out in F344 rats; the highest dose used was approximately 45 mg/kg/day.

In a 24-week study of racemic methylphenidate in the transgenic mouse strain p53+/-, which is sensitive to genotoxic carcinogens, there was no evidence of carcinogenicity. Mice were fed diets containing the same concentrations as in the lifetime carcinogenicity study; the high-dose group was exposed to 60-74 mg/kg/day of racemic methylphenidate.Dexmethylphenidate was not mutagenic in the in vitro Ames reverse mutation assay, the in vitro mouse lymphoma cell forward mutation assay, or the in vivo mouse bone marrow micronucleus test.

Racemic methylphenidate was not mutagenic in the in vitro Ames reverse mutation assay or the in vitro mouse lymphoma cell forward mutation assay, and was negative in vivo in the mouse bone marrow micronucleus assay. However, sister chromatid exchanges and chromosome aberrations were increased, indicative of a weak clastogenic response, in an in vitro assay of racemic methylphenidate in cultured Chinese Hamster Ovary (CHO) cells.

Racemic methylphenidate did not impair fertility in male or female mice that were fed diets containing the drug in an 18-week Continuous Breeding study. The study was conducted at doses of up to 160 mg/kg/day.

Pregnancy

Pregnancy Category C

In studies conducted in rats and rabbits, dexmethylphenidate was administered orally at doses of up to 20 and 100 mg/kg/day, respectively, during the period of organogenesis. No evidence of teratogenic activity was found in either the rat or rabbit study; however, delayed fetal skeletal ossification was observed at the highest dose level in rats. Whendexmethylphenidate was administered to rats throughout pregnancy and lactation at doses of up to 20 mg/kg/day, postweaning body weight gain was decreased in male offspring at the highest dose, but no other effects on postnatal development were observed. At the highest doses tested, plasma levels (AUCs) of dexmethylphenidate in pregnant rats and rabbits were approximately 5 and 1 times, respectively, those in adults dosed with the maximum recommended human dose of 20 mg/day.

methylphenidate has been shown to have teratogenic effects in rabbits when given in doses of 200 mg/kg/day throughout organogenesis. Adequate and well-controlled studies in pregnant women have not been conducted. Focalin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Nursing Mothers

It is not known whether dexmethylphenidate is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised if Focalin is administered to a nursing woman.

Pediatric Use

The safety and efficacy of Focalin in children under 6 years old have not been established. Long-term effects of Focalin in children have not been well established In a study conducted in young rats, racemic methylphenidate was administered orally at doses of up to 100 mg/kg/day for 9 weeks, starting early in the postnatal period (Postnatal Day 7) and continuing through sexual maturity (Postnatal Week 10). When these animals were tested as adults (Postnatal Weeks 13-14), decreased spontaneous locomotor activity was observed in males and females previously treated with 50 mg/kg/day (approximately 6 times the maximum recommended human dose [MRHD] of racemic methylphenidate on a mg/m2 basis) or greater, and a deficit in the acquisition of a specific learning task was seen in females exposed to the highest dose (12 times the racemic MRHD on a mg/m2 basis). The no effect level for juvenile neurobehavioral development in rats was 5 mg/kg/day (half the racemic MRHD on a mg/m2 basis). The clinical significance of the long-term behavioral effects observed in rats is unknown.
