Do not start, stop, or change the dose of any medication without consulting your doctor.
Precautions & Cautions
It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication. If you are scheduled to have surgery, be sure to discuss this with your doctor beforehand.
To ensure your safety, avoid driving and engaging in activities that require alertness until you understand how this medication affects you. Regularly monitor your blood work, blood pressure, and heart rate as directed by your doctor. You may need to undergo certain heart tests before starting this medication; if you have questions or concerns, consult with your doctor.
While taking this medication, it is recommended that you avoid consuming alcohol and limit your intake of caffeine (found in tea, coffee, cola, and chocolate), as combining these substances may cause nervousness, shakiness, and a rapid heartbeat.
If you have high blood pressure, it is crucial to discuss the use of over-the-counter (OTC) products with your doctor before taking them, as some may increase blood pressure. These products include cough and cold medications, diet pills, stimulants, non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, and certain natural products or aids.
Long-term or high-dose use of this medication may lead to tolerance, reducing its effectiveness and potentially requiring higher doses to achieve the same effect. If you notice that the medication is no longer working as well, contact your doctor. Do not exceed the prescribed dose.
This medication may increase the risk of seizures in certain individuals, particularly those with a history of seizures. Consult with your doctor to determine if you are at a higher risk of seizures while taking this medication.
If you are allergic to tartrazine (FD&C Yellow No. 5), inform your doctor, as some products contain this ingredient.
In some cases, this medication may affect growth in children and teenagers, requiring regular growth checks. Discuss this with your doctor.
If you are pregnant, plan to become pregnant, or are breastfeeding, it is essential to discuss the benefits and risks of this medication with your doctor to ensure the best possible outcome for you and your baby.

Special Patient Groups
Pregnancy
Use during pregnancy should only be considered if the potential benefit justifies the potential risk to the fetus. There are no adequate and well-controlled studies in pregnant women. Animal studies have shown some evidence of developmental toxicity at doses higher than therapeutic human doses.
Trimester-Specific Risks:
Lactation
Methylphenidate is excreted into human milk. Monitor breastfed infants for signs of adverse reactions such as agitation, insomnia, anorexia, or decreased weight gain. The decision to breastfeed should consider the developmental and health benefits of breastfeeding, the motherβs clinical need for Ritalin LA, and any potential adverse effects on the breastfed infant from Ritalin LA or from the underlying maternal condition.
Pediatric Use
Approved for children 6 years and older. Monitor growth (height and weight) and cardiovascular parameters. Long-term safety and efficacy in children younger than 6 years have not been established.
Geriatric Use
Clinical studies of Ritalin LA did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Clinical Information
Clinical Pearls
- Ritalin LA is an extended-release formulation designed for once-daily dosing, providing approximately 8 hours of effect.
- The capsule can be opened and sprinkled on applesauce for patients who have difficulty swallowing pills, but the entire contents must be consumed immediately without chewing.
- Patients should be advised to take the medication in the morning to avoid insomnia.
- Regular monitoring of blood pressure and heart rate is crucial due to the cardiovascular effects of stimulants.
- In pediatric patients, growth (height and weight) should be monitored regularly due to the potential for growth suppression.
- Patients should be screened for pre-existing cardiac conditions and psychiatric disorders before initiating therapy.
Alternative Therapies
- Other methylphenidate formulations (e.g., Concerta, Daytrana, Quillivant XR, Aptensio XR, Jornay PM, Focalin XR)
- Amphetamine-based stimulants (e.g., Adderall XR, Vyvanse, Dexedrine)
- Non-stimulants (e.g., Atomoxetine, Guanfacine ER, Clonidine ER)
- Behavioral therapy and psychotherapy
