Additionally, prolonged use of this drug may cause addiction, manic disorders, and exacerbation of pre-existing psychotic disorders. To understand more, the information in this section will explain.

Addiction to Dexmethylphenidate

At higher doses, Dexmethylphenidate adverse effects include euphoria, increased focus, self-confidence, sociability, energy, weight loss, staying awake for longer hours, but also paranoia, delusions, hallucinations, aggression, irritability, and even severe cardiac conditions.

Manic or Psychotic Symptoms

Dexmethyphenidate 10 mg, the usual prescribed dose for ADHD, can also cause manic or psychotic symptoms in the form of mania, delusional thinking, or hallucinations in teenagers and children. These Focalin emotional side effects can take place even in patients without a history of mania or psychotic illness.

  • New or worse bipolar illness
  • New or worse aggressive behavior or hostility

These adverse reactions have been seen in patients with structural cardiac abnormalities at standard doses of Dexmethylphenidate. The drug should not be administered in patients with severe heart rhythm and structural cardiac abnormalities, coronary artery disease, or cardiomyopathy. Patients who experience unexplained syncope, chest pain, trouble breathing, or arrhythmias should immediately contact their physician.

Another of the Dexmethylphenidate adverse reactions that require immediate medical attention is priapism, a prolonged erection of the penis with pain that is not caused by sexual stimulation.ย  Moreover, priapism is caused by the treatment with Dexmethylphenidate and it has been reported in both young and adult patients who are taking this drug.

Medical attention is needed for children treated with Dexmethylphenidate who are not gaining weight or height as expected. In such cases, the treatment should be immediately interrupted.

Focalin weight loss

Dexmethylphenidate affects the metabolism and nutrition of a patient. Moreover, prolonged Dexmethylphenidate therapy can result in weight loss. This is related to one of the side effects of Focalin which is loss of appetite. Weight loss is dependent on the dose of Dexmethylphenidate. In one study, as the dose of the Dexmethylphenidate increases, an increase in clinical Focalin weight loss is also seen.

According to the federal government, Dexmethylphenidate is required to carry a black-box warning. There is the possibility of habit-forming and chronic abuse can result in psychological dependence and a marked tolerance. These can be associated with abnormal behavior, depression from abusive use, withdrawal, and frank psychotic episodes.

Continuous monitoring should take place to assess any signs of abuse and dependence during the treatment. The withdrawal from prolonged Dexmethylphenidate treatment may resurface symptoms of the underlying condition that may need follow-up. Additionally, sudden death and cardiac abnormalities can also happen in the case of the abuse or misuse of this medication.

Focalin Overdose

Variables That Affect Side Effects Emergence

The incidence of Focalin side effects depends on many factors, such as body weight, metabolism, tolerance, and personal sensitivity. But other variables should be taken into consideration. In this section, information about the list of variables that affect the emergence of the adverse reactions of Dexmethylphenidate will be provided.

Age

Geriatric patients might be more prone to experiencing Focalin side effects. The drug should be used with caution due to an increased incidence of cardiac disease. Dexmethylphenidate is usually prescribed when lifestyle and behavioral modifications have failed to improve ADHD symptoms.

Geriatric Patients Are More Susceptible to Specific Adverse Reactions Such as:ย 

  • insomnia
  • tremor
  • behavior and mood changes
  • headache
  • increased blood pressure
  • gastroesophageal reflux

Certain eating disorders

Patients with eating disorders, such as bulimia nervosa or anorexia nervosa, may present metabolic abnormalities and physiologic complications that can augment the side effects of Focalin XR or its plain form. The drug is known for causing weight loss and appetite suppression, so the incidence of abuse in such patients is increased.

Individual tolerance

Chronic use of Dexmethylphenidate can lead to psychological dependence and marked tolerance, associated with frank psychotic episodes, abnormal behavior, and Dexmethylphenidate depression. Careful attention is required during the withdrawal after chronic use of the drug.

Preventing Focalin Side Effects

To prevent the occurrence of the side effects of Focalin XR or its plain form, it is important to know the information about how long Dexmethylphenidate stays in the system. Dexmethylphenidate has a half-life varying from 2.2 hours to 7 hours, depending on the drugโ€™s release time. This will aid in understanding how long the adverse reactions might last. But there are also some things that can make these be reduced or even prevented.

  1. Take the medication with a meal and keep drinking lots of water to prevent dehydration. In the case of dizziness, talk to a doctor to have a blood pressure check and readjust the dosage.
  2. Try eating several smaller meals, not three big ones and have dinner at a later time in the evening after the medicationโ€™s side effects have worn off. There is a connection between Dexmethylphenidate and weight loss due to the loss of appetite. Talk to a doctor if too much weight is lost during the treatment.
  3. Drink plenty of water to avoid having a dry mouth. Lozenges might also help in keeping the mouth moist.

However, all these tips will not be useful in case of drug abuse and addiction. Get in touch with medical professionals to get referred to the best addiction treatment options in the state. In some cases, rehabilitation in one of the substance dependence centers will be necessary.
