Serdexmethylphenidate and Dexmethylphenidate

The combination of serdexmethylphenidate and dexmethylphenidate can be habit-forming. Do not take a larger dose, take it more often, or take it for a longer time than prescribed by your doctor. If you take too much serdexmethylphenidate and dexmethylphenidate, you may continue to feel a need to take large amounts of the medication, and you may experience unusual changes in your behavior. You or your caregiver should tell your doctor immediately if you experience any of the following symptoms: fast, pounding, or irregular heartbeat; sweating; dilated pupils; abnormally excited mood; restlessness; irritability; difficulty falling sleeping or staying asleep; hostility; aggression; anxiety; loss of appetite; loss of coordination; uncontrollable movement of a part of the body; flushed skin; vomiting; stomach pain; or thinking about harming or killing oneself or others or planning or trying to do so.

Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications.

Do not stop taking serdexmethylphenidate and dexmethylphenidate without talking to your doctor, especially if you have overused the medication. Your doctor will probably decrease your dose gradually and monitor you carefully during this time. You may develop severe depression and extreme tiredness if you suddenly stop taking serdexmethylphenidate and dexmethylphenidate after overusing it. Your doctor may need to monitor you carefully after you stop taking serdexmethylphenidate and dexmethylphenidate, even if you have not overused the medication, because your symptoms may worsen when treatment is stopped.

Do not sell, give away, or let anyone else take your medication. Selling or giving away serdexmethylphenidate and dexmethylphenidate may harm others and is against the law. Store serdexmethylphenidate and dexmethylphenidate in a safe place so that no one else can take it accidentally or on purpose. Keep track of how many capsules are left so you will know if any are missing.

Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with serdexmethylphenidate and dexmethylphenidate and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer’s website to obtain the Medication Guide.

🔔 Why is this medication prescribed?

The combination of serdexmethylphenidate and dexmethylphenidate is used as part of a treatment program to control symptoms of attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age) in adults and children 6 years of age and older. The combination of serdexmethylphenidate and dexmethylphenidate is in a class of medications called central nervous system stimulants. These medications work by changing the amounts of certain natural substances in the brain.

Interestingly, Americans show more favor toward Medicare for All healthcare initiatives than they do toward these efforts when they are labeled as “single payer,” most likely due to the popularity of the Medicare program, STAT

🔔 How should this medicine be used?

The combination of serdexmethylphenidate and dexmethylphenidate comes as a capsule to take by mouth. It is usually taken once daily in the morning with or without food. Take serdexmethylphenidate and dexmethylphenidate at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take serdexmethylphenidate and dexmethylphenidate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the capsules whole; do not chew or crush them. If you are unable to swallow the capsule, you may open the capsule and sprinkle the entire contents into about 2 oz (50 mL) of water or onto 2 teaspoonsful of applesauce. Swallow or eat this mixture right away within 10 minutes of mixing. Do not store the medication mixture for future use.

Your doctor will probably start you on a low dose of serdexmethylphenidate and dexmethylphenidate and increase your dose gradually, not more often than once every week.

Your condition should improve during your treatment. Call your doctor if your symptoms worsen at any time during your treatment or do not improve after 1 month.

🔔 What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program.
