Without first seeing your doctor, do not discontinue taking serdexmethylphenidate or dexmethylphenidate, especially if you have taken too much of the medicine.

Serdexmethylphenidate and dexmethylphenidate are used together as part of a treatment programme to manage the signs and symptoms of attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people their age). This condition affects both adults and children 6 years of age and older. In a group of drugs known as central nervous system stimulants, serdexmethylphenidate and dexmethylphenidate are combined. The level of a few natural chemicals in the brain is altered by these drugs.

Serdexmethylphenidate and dexmethylphenidate are sold as a capsule to be swallowed. It is often taken in the morning, with or without meals, once day. Dexmethylphenidate and serdexmethylphenidate should be taken at roughly the same time each day. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Dexmethylphenidate and serdexmethylphenidate should be taken exactly as prescribed. Never take it in larger or less amounts or more frequently than directed by your doctor.

Avoid chewing or crushing the pills; simply swallow them whole. If you are unable to take the capsule, you can open it and sprinkle the entire contents onto 2 teaspoons of applesauce or roughly 50 millilitres (2 oz) of water. After mixing for 10 minutes, immediately swallow or consume the concoction. Don’t keep the drug mixture on hand for later use.

Serdexmethylphenidate and dexmethylphenidate will likely be prescribed to you at a low starting dose by your doctor, who will then progressively raise it up to once per week.

Throughout your treatment, your condition ought to become better. If your symptoms get worse at any point while you’re receiving therapy or if they don’t get better after a month, call your doctor.

Ask your doctor or pharmacist for more details if you believe this drug should be used for something else.

As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org
