What are the guidelines for using signal (transdermal) patches for therapeutic purposes, such as pain management or smoking cessation?

From the Guidelines

Transdermal patches, such as nicotine patches, should be used as part of a comprehensive smoking cessation program, including behavioral counseling and support, to increase the chances of successful quitting. When using signal patches for therapeutic purposes, such as pain management or smoking cessation, it is essential to follow the guidelines and recommendations provided by the manufacturer and healthcare professionals.

Key Considerations for Using Transdermal Patches

• Apply patches to clean, dry, hairless skin in areas recommended by the manufacturer, typically the upper arm, chest, or back, and rotate to prevent skin irritation.
• For pain management, patches like fentanyl (12-100 mcg/hr) should be changed every 72 hours, while buprenorphine patches (5-20 mcg/hr) last 7 days.
• Nicotine patches for smoking cessation typically follow a step-down approach over 8-12 weeks, starting with higher doses (21 mg/24hr) and gradually decreasing (14 mg/24hr, then 7 mg/24hr) 1.
• Always wash hands before and after application, avoid cutting patches, and dispose of used patches properly by folding sticky sides together and placing in childproof containers.
• Patches work by delivering medication through the skin at a controlled rate, bypassing the digestive system and providing steady blood levels, which avoids first-pass metabolism in the liver, allowing for lower doses and fewer side effects than oral medications 1.

Important Safety Precautions

• If a patch falls off, replace it immediately, and never use heat sources like heating pads over patch areas as this can increase drug absorption and lead to overdose.
• Remove patches before MRI procedures, as some contain metal components that could cause burns.
• Combining behavioral and pharmacotherapy interventions, including the use of transdermal patches, may increase cessation rates from approximately 8% to 14% compared with usual care or minimal behavioral interventions 1.

Evidence-Based Recommendations

• The use of nicotine transdermal patches, lozenges, gum, inhalers, or nasal spray, as well as bupropion SR and varenicline, are approved by the FDA for the treatment of tobacco dependence in adults 1.
• Evidence suggests that rates of smoking abstinence may increase from approximately 10% in control groups (placebo or no pharmacotherapy) to 17% in persons using any form of NRT, from roughly 11% in control groups (placebo or no bupropion SR) to 19% in those using bupropion SR, and from approximately 12% in control groups (placebo) to 28% in those using varenicline 1.
• Using 2 types of NRT has been found to be more effective than using a single type, and combining a nicotine patch with a rapid-delivery form of NRT is more effective than using a single type 1.

Hold for 10 seconds. wash hands after applying or removing patch. TO INCREASE YOUR SUCCESS IN QUITTING: 1. You must be motivated to quit. 2. Use one patch daily according to directions. 3. It is important to complete treatment. 4. If you feel you need to use the patch for a longer period to keep from smoking, talk to your health care provider. 5. Use patch with a behavioral support program such as the one described in the enclosed booklet.

The guidelines for using signal (transdermal) patches, specifically nicotine patches for smoking cessation, are as follows:

• Apply one new patch every 24 hours on skin that is dry, clean, and hairless.
• Remove the backing from the patch and immediately press onto skin, holding for 10 seconds.
• Do not wear more than one patch at a time.
• Do not cut the patch in half or into smaller pieces.
• Do not leave the patch on for more than 24 hours.
• Follow the recommended schedule:
  • If you smoke more than 10 cigarettes per day:
    • Step 1 (Weeks 1-2): Use one 21 mg patch/day.
    • Step 2 (Weeks 3-4): Use one 14 mg patch/day.
    • Step 3 (Weeks 5-6 and 7-8): Use one 7 mg patch/day.
  • If you smoke 10 or less cigarettes per day, start with Step 2 for 6 weeks, then Step 3 for 2 weeks.
• It is also recommended to use the patch with a behavioral support program and to complete treatment as directed 2 2.

From the Research

Guidelines for Using Signal Patches

• The use of transdermal nicotine patches for smoking cessation has been studied extensively, with research indicating that these patches can be an effective aid in quitting smoking 3, 4, 5, 6, 7.
• Studies have shown that nicotine patches can produce end-of-treatment smoking cessation rates that range from 18% to 77%, with 6-month abstinence rates of 22% to 42% 7.
• The effectiveness of transdermal nicotine patches can be influenced by various factors, including negative affect and physical symptoms, with research suggesting that the patches may be less effective in females with higher levels of negative affect and pain 3.
• Adherence to transdermal nicotine patches is also an important factor, with research indicating that difficulties in adhering to the patches may be related to psychiatric comorbidity, difficulty managing nicotine craving, and challenges with engaging in substitute reinforcers and reducing exposure to complementary reinforcers 5.
• Proper adjuvant smoking cessation counseling is crucial in determining successful long-term outcome with the nicotine patch, with research suggesting that 6 to 8 weeks of patch therapy may be an adequate duration for most patients 7.

Factors Influencing Patch Effectiveness

• Negative affect and physical symptoms can influence the effectiveness of transdermal nicotine patches, with research suggesting that the patches may be less effective in females with higher levels of negative affect and pain 3.
• History of depression can also impact the effectiveness of transdermal nicotine patches, with research indicating that a history of depression is associated with a decreased likelihood to abstain from smoking throughout the study 6.
• Hormone replacement therapy (HRT) does not appear to moderate smoking outcomes in postmenopausal women using transdermal nicotine patches 6.

Patch Administration and Adherence

• Transdermal nicotine patches are typically administered for 6 to 8 weeks, with a tapering schedule to reduce the risk of side effects 4, 7.
• Adherence to the patches is critical, with research indicating that difficulties in adhering to the patches may be related to psychiatric comorbidity, difficulty managing nicotine craving, and challenges with engaging in substitute reinforcers and reducing exposure to complementary reinforcers 5.
• Side effects of transdermal nicotine patches are generally mild, with skin irritation at the patch site and abnormal dreams being the most common complaints 4, 7.
