How to Use This Medicine

Proper Use of This Medication

To use this medication correctly, follow your doctor's instructions and read all the information provided. It's essential to follow these guidelines carefully.

Do not cut or divide the patches, and avoid using patches that are damaged.
Before and after handling the patch, wash your hands thoroughly.
Apply the patch to clean, dry, and healthy skin on your hip, avoiding the waistline. Do not apply the patch to cuts, scrapes, eczema, or damaged skin.
Put on the patch in the morning and remove it 9 hours later, or as directed by your doctor.
Each time you change the patch, apply it to a new area of skin.
Be aware that water from bathing, swimming, or showering may cause the patch to lose its adhesion or fall off. If the patch falls off, avoid touching the sticky side with your fingers.
* If the patch falls off, apply a new one to a different area of the same hip. Remove the new patch at the usual time.

Storage and Disposal

Precautions & Cautions

Important Warnings and Cautions

Before taking this medication, inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are using this drug. If you are scheduled to have surgery, 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, consult your doctor.

It is recommended that you avoid consuming alcohol while taking this medication. Additionally, limit your intake of caffeine (found in tea, coffee, cola) and chocolate, as combining these with this drug may cause nervousness, shakiness, and a rapid heartbeat.

If you have high blood pressure, consult your doctor before using over-the-counter (OTC) products that may increase blood pressure, such as cough or 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, where the drug becomes less effective, and higher doses may be required to achieve the same effect. If you experience this, contact your doctor; do not take more than the prescribed amount.

This medication may increase the risk of seizures in some individuals, particularly those with a history of seizures. Discuss your risk with your doctor.

Seek immediate medical attention if you experience a painful erection (priapism) or an erection lasting longer than 4 hours, as this can lead to lasting sexual problems if not treated promptly.

Avoid exposure to heat sources, such as sunlamps, tanning beds, heating pads, electric blankets, heat lamps, saunas, hot tubs, and heated waterbeds. Also, avoid taking long, hot baths or sunbathing, as your body temperature may rise, causing excessive medication to be absorbed.

Using this medication may cause skin discoloration at or around the patch application site, and in some cases, at other areas. This effect may persist even after stopping the medication, particularly if you or a family member has a history of vitiligo. Consult your doctor about this risk.

Special Patient Groups

🤰

Pregnancy

Category C. Studies in animals have shown adverse effects on fetal development at doses higher than human therapeutic doses. There are no adequate and well-controlled studies in pregnant women. Use only if the potential benefit justifies the potential risk to the fetus.

Trimester-Specific Risks:

First Trimester: Potential for increased risk of cardiac malformations (e.g., atrial septal defects) based on some observational studies, though data are conflicting and overall risk appears low.

Second Trimester: Limited data, but generally considered lower risk than first trimester for major malformations.

Third Trimester: Potential for premature birth and low birth weight. Neonatal withdrawal symptoms (e.g., agitation, tremor, poor feeding) have been reported with stimulant use near term.

🤱

Lactation

Methylphenidate is excreted into human milk. The American Academy of Pediatrics considers methylphenidate to be compatible with breastfeeding, but caution is advised. Monitor breastfed infant for adverse effects (e.g., irritability, poor feeding, sleep disturbances, weight loss).

Infant Risk: Low to moderate risk. Monitor for irritability, poor sleep, and weight gain issues. Consider using the lowest effective dose and timing doses to minimize infant exposure (e.g., after the longest sleep period).

👶

Pediatric Use

FDA-approved for ADHD in children and adolescents 6 to 17 years of age. Monitor growth (height and weight) carefully. Risk of growth suppression, though long-term impact is often minimal or reversible. Monitor for psychiatric adverse events.

👴

Geriatric Use

Safety and efficacy have not been established in geriatric patients. Use with caution due to potential for increased sensitivity to adverse effects, particularly cardiovascular effects. Start with lower doses and titrate slowly.

Clinical Information

💎

Clinical Pearls

The transdermal patch offers a non-oral alternative for ADHD treatment, which can be beneficial for patients with dysphagia or those who prefer not to take daily pills.
The 9-hour wear time allows for flexible dosing to cover school/work hours and then be removed to potentially reduce evening appetite suppression or sleep disturbances.
Skin irritation at the application site is a common adverse effect. Rotate application sites daily (e.g., left hip, right hip) and ensure skin is clean and dry. Topical corticosteroids may be used for severe irritation.
Patients should be advised to avoid external heat sources (e.g., hot baths, heating pads) on the patch, as this can significantly increase drug absorption and lead to overdose.
The patch continues to deliver medication for several hours after removal due to a drug reservoir in the skin, contributing to its prolonged duration of action.
Titration should be gradual, typically weekly, to assess efficacy and tolerability.

🔄

Alternative Therapies
