Withdrawal from Ritalin (methylphenidate) can vary in duration and severity depending on the individual and the extent of their use. Generally, acute withdrawal symptoms may begin a few hours to a few days after the last dose, with the most intense symptoms occurring within the first few days and gradually subsiding over the following weeks.
Withdrawal symptoms can last anywhere from a few days to several weeks, and in some cases, months. Some common withdrawal symptoms include fatigue, insomnia, depression, anxiety, irritability, mood swings, and difficulty concentrating. It is important to note that withdrawal from Ritalin should be done under the guidance of a medical professional to minimize the risk of complications and ensure a safe and comfortable recovery.
