Ritalin, the brand name of the medication methylphenidate, is used to treat attention-deficient hyperactivity disorder (ADHD) and narcolepsy. Although it can effectively treat the symptoms of these conditions, side effects can occur. The most common side effects that occur with the use of Ritalin, however, are generally not serious and only need to be reported to a doctor if they are persistent or become bothersome, according to Drugs.com.
Trouble Sleeping
The Ritalin product information sheet indicates that insomnia is one of the most common side effects of this medication. However, you can take steps to eliminate or reduce this side effect. Taking the medication earlier in the day, preferably in the morning instead of the afternoon or evening, can help minimize this effect. If that doesn't work, talking to your doctor about reducing the dosage may also help, suggests the product information sheet.
Nervousness
Nervousness is the second most common side effect of Ritalin, according to the Ritalin product information sheet. As in the case of insomnia, taking the medication in the morning and reducing the dosage may minimize or eliminate this reaction.
Gastrointestinal Issues
Stomach pains, nausea or a loss of appetite also are common side effects of taking Ritalin. Although these side effects should go away on their own as the body gets used to the medication, any severe pains or troublesome gastrointestinal issue should be reported to a doctor.
Headaches
Headaches are commonly experienced when taking Ritalin. The frequency and severity of these headaches can vary, depending on the individual and the specific situation. Drugs.com indicates that the pain and occurrence of headaches should gradually lessen over time.
Dizziness
Dizziness, which means to experience a whirling sensation and feel as if you are about to fall, is a common side effect of Ritalin. Although this effect is generally not considered serious, call a doctor if it becomes particularly bothersome or does not seem to go away as the body gets used to the medication.
Drowsiness
Drowsiness, a state of decreased awareness associated with a strong desire to sleep, can also commonly occur when taking Ritalin. People feeling drowsy should not put themselves in situations that require full alertness, such as driving or operating heavy machinery, warns Drugs.com.
