Focalin or dexmethylphenidate refers to a drug which acts as a mild stimulant for the central nervous system. This medication is primarily used to treat Attention Deficit Hyperactivity Disorder (ADHD) because it can affect the amounts of certain chemicals in the brain that are responsible for impulse control and hyperactivity.

Focalin can help control behavioral problems, maintain focus, enhance the listening skills, and improve the ability of a person to pay attention. Additionally, this drug can also make an individual become more organized and is also used for the treatment of a sleep disorder called narcolepsy.

Some of the side effects of this drug include nausea, mild fever, decreased appetite, pain in the stomach, and weight loss. If a person taking this drug exhibits certain symptoms of an allergic reaction such as breathing difficulties, hives, and swelling around the mouth, throat, tongue, and face, it is advisable to seek professional help immediately.

Additionally, it is recommended to call a physician and discontinue taking Focalin if the patient experiences chest pains, irregular heartbeats, high blood pressure, numbness, changes in skin color, muscle twitches, weakness on one side of the body, hallucinations, mood swings, slurred speech, aggression, severe headache, buzzing in the ears, vision problems, and seizures.

Before taking Focalin, inform the doctor about problems with blood circulation, heart conditions, and other health issues such as high blood pressure, glaucoma, hyperthyroidism, and disorders that involve uncontrolled movements of the muscles and seizures. Mood disorders and mental conditions including depression, anxiety, psychosis, and bipolar disorder must also be reported to the physician.

Long-term use of this drug can affect the growth rate of a child, adult height, and weight. With this, it is recommended to discontinue the use of Focalin from time to time, regularly check the weight and height of the child, and seek professional medical advice regarding this. Pregnant women must also take precautions and use this drug only when it is absolutely needed. Finally, older adults are more likely to experience side effects such as chest pains, weight loss, and sleeping problems.
