Mydayis is a once-daily stimulant medication used to treat ADHD/ADD symptoms in adolescents and adults 13 and older.
Generic Name: Mixed salts of a single-entity amphetamine product
What is Mydayis?
Mydayis is a long-acting, triple-bead, mixed amphetamine salts formulation used for once-daily treatment of symptoms of attention deficit disorder (ADHD or ADD) in adolescents and adults 13 and older. According to the FDA, Mydayis is a federally controlled substance (CII) because it can be abused or lead to dependence. It is an amphetamine.
Mydayis may improve focus for people with inattentive ADHD, and decrease impulsivity and hyperactive behavior as well. Children under 13 years of age who used Mydayis experienced higher plasma exposure and more frequent adverse reactions, including insomnia and decreased appetite.
The National Institute of Mental Health finds the most successful treatment plans use a combination of ADHD medication, like Mydayis, and behavior therapies.
How Do You Use Mydayis to Treat ADD?
Before starting or refilling a Mydayis prescription, read the medication guide included with your pills, as it may be updated with new information.
This guide should not replace a conversation with your doctor, who has a holistic view of your or your child’s medical history, other diagnoses, and other prescriptions. If you have questions, ask your doctor or pharmacist before you begin taking the medication.
What is the Typical Dosage for Mydayis?
As with all medications, follow your Mydayis prescription instructions exactly. Mydayis is taken orally, with or without food, once daily. The first dose is typically administered upon awakening because the effects can last up to 16 hours, and there is potential for insomnia; it should be taken at the same time each day for the best results.
Do not drink alcohol while taking Mydayis.
Capsules should be swallowed whole with water or other liquids. If your adolescent is unable to swallow the capsule, it can be opened and sprinkled over a spoonful of applesauce. Taken this way, the mixture should be swallowed whole without chewing, followed by a drink of water or other liquid.
Capsules are available in 12.5mg, 25mg, 37.5mg, and 50mg dosages. The time-release formulation is designed to maintain a steady level of medication in your body throughout the day.
The optimal dosage varies patient by patient. Your doctor may adjust your daily dosage by 12.5mg increments until you or your adolescent experiences the best response — that is, the lowest dosage at which you experience the greatest improvement in ADD symptoms without side effects.
Adolescents should not exceed 25mg daily. The maximum daily dose for adults is 50mg. Taking a high dosage for a prolonged time can result in withdrawal symptoms like fatigue and depression with abrupt cessation. If you or your teen exceeds the prescribed dosage, call your doctor or poison control, or seek emergency medical care.
During treatment, your doctor may periodically ask you to stop taking Mydayis so that he or she can monitor ADHD symptoms; check vital statistics including blood pressure and heart rate; or evaluate height and weight. If any problems are found, your doctor may recommend discontinuing treatment.
Some patients report developing a tolerance to amphetamines like Mydayis after long-term usage. If you notice that your dosage is no longer controlling your symptoms, talk to your doctor to plan a course of action.
What Side Effects Are Associated with Mydayis?
The most common side effects of Mydayis are as follows:
Adolescents (ages 13 to 17): insomnia, decreased appetite, decreased weight, irritability, and nausea.
Adults: insomnia, decreased appetite, decreased weight, dry mouth, increased heart rate, and anxiety.
Other serious side effects include slowed growth in adolescents, seizures, and new or exacerbated heart or mental problems. If side effects are bothersome, or do not go away, talk to your doctor.
Most people taking this medication do not experience any of these side effects.
Report to your doctor any heart-related problems or a family history of heart and blood pressure problems. Patients with structural cardiac abnormalities and other serious heart problems could experience sudden death, stroke, heart attack, and increased blood pressure while taking Mydayis. Stimulants can increase blood pressure and heart rate. Physicians should monitor these vital signs closely during treatment. Call your doctor immediately if you or your child experiences warning signs such as chest pain, shortness of breath, or fainting while taking Mydayis.
Also disclose to your physician all mental health issues including any family history of suicide, bipolar illness, or depression. The drug manufacturer, Shire, recommends evaluating patients for bipolar disorder prior to stimulant administration. Mydayis may create new or exacerbate existing behavior problems, bipolar illness, or psychosis. Call your doctor immediately if you or your teen experiences new or worsening mental health symptoms including hallucinations or sudden suspicions.
Discuss circulation problems with your doctor before taking Mydayis, which has been known to cause numbness, coolness, or pain in fingers or toes, including Raynaud’s phenomenon. Report to your doctor any new blood-flow problems, pain, skin color changes, or sensitivities to temperature while taking Mydayis.
Mydayis can rarely lead to life-threatening serotonin syndrome, or toxicity, especially when co-administered with serotonergic agents like SSRIs or SNRIs. If you experience changes in mental status, coordination problems, muscle twitching, racing heartbeat, high or low blood pressure, sweating, vomiting or diarrhea, seek medical help immediately.
Amphetamines like Mydayis have a high potential for abuse and dependence, especially among people who do not have ADHD. It is a “Schedule II Stimulant,” a designation that the Drug Enforcement Agency uses for drugs with a high potential for abuse. Other Schedule II drugs include Dexedrine, Ritalin, and cocaine. People with a history of drug abuse should use caution when trying this medication. Taking the medication exactly as prescribed can reduce potential for abuse.
The above is not a complete list of potential side effects. If you notice any health changes not listed above, discuss them with your doctor or pharmacist.
What Precautions Are Associated with Mydayis?
Store Mydayis in a secure place out of the reach of children, and at room temperature. Do not share your Mydayis prescription with anyone, even another person with ADHD. Sharing prescription medication is illegal, and can cause harm.
You should not take Mydayis if you are in kidney failure, or have taken monoamine oxidase inhibitors (MAOIs) within 14 days.
If you’re thinking of becoming pregnant, discuss the use of Mydayis with your doctor. Animal studies indicate a potential risk of fetal harm; infants may be born prematurely, with low birth weight, have learning or motor deficits, or experience withdrawal. Mydayis is passed through breastmilk, so it is recommended that mothers do not nurse while taking it.
The effects of Mydayis on the elderly have not been sufficiently studied.
What Interactions Are Associated with Mydayis?
Before taking Mydayis, discuss all other active prescription medications with your doctor. Mydayis can have a dangerous, possibly fatal, interaction with antidepressants including MAOIs.
Do not take Mydayis if you are taking an alkalinizing or acidifying agent to treat renal failure.
Share a list of all vitamin or herbal supplements, and prescription and non-prescription medications you take with the pharmacist when you fill your prescription, and let all doctors and physicians know you are taking Mydayis before having any surgery or laboratory tests. The above is not a complete list of all possible drug interactions.
