This drug is an amphetamine, you will want to gradually reduce the dosage to get off it as it is highly addictive. Read up on it and learn all about it. https://en.wikipedia.org/wiki/Methylphenidate Addiction experts in psychiatry, chemistry, pharmacology, forensic science, epidemiology, and the police and legal services engaged in delphic analysis regarding 20 popular recreational drugs. Methylphenidate was ranked 13th in dependence, 12th in physical harm, and 18th in social harm. Methylphenidate is generally well tolerated. The most commonly observed adverse effects with a frequency greater than placebo include appetite loss, dry mouth, anxiety/nervousness, nausea, and insomnia. Gastrointestinal adverse effects may include abdominal pain and weight loss. Nervous system adverse effects may include akathisia (agitation/restlessness), irritability, dyskinesia (tics), lethargy (drowsiness/fatigue), and dizziness. Cardiac adverse effects may include palpitations, changes in blood pressure and heart rate (typically mild), tachycardia (rapid resting heart rate), and Raynaud's phenomenon (reduced blood flow to the hands and feet). Ophthalmologic adverse effects may include blurred vision and dry eyes, with less frequent reports of diplopia and mydriasis. Other adverse effects may include depression, emotional lability, confusion, and bruxism. Hyperhidrosis (increased sweating) is common. Chest pain is rarely observed. There is some evidence of mild reductions in growth rate with prolonged treatment in children, but no causal relationship has been established and reductions do not appear to persist long-term. Hypersensitivity (including skin rash, urticaria, and fever) is sometimes reported. The Daytrana patch has a much higher rate of dermal reactions than oral methylphenidate. Methylphenidate can worsen psychosis in psychotic patients, and in very rare cases it has been associated with the emergence of new psychotic symptoms. It should be used with extreme caution in patients with bipolar disorder due to the potential induction of mania or hypomania. There have been very rare reports of suicidal ideation, but the evidence does not support a link. Logorrhea is occasionally reported. Libidodisorders, disorientation, and hallucinations are very rarely reported. Priapism is a very rare adverse event that can be potentially serious. USFDA-commissioned studies from 2011 indicate that in children, young adults, and adults there is no association between serious adverse cardiovascular events (sudden death, heart attack, and stroke) and the medical use of methylphenidate or other ADHD stimulants. Because some adverse effects may only emerge during chronic use of methylphenidate, a constant watch for adverse effects is recommended.
