Dozens of medications come in patch form, covering everything from pain relief and hormone replacement to smoking cessation, ADHD, and Alzheimer’s disease. The FDA has approved transdermal patches for at least 16 different drugs, and several more are available over the counter. These patches stick to your skin and deliver a steady dose of medication into your bloodstream over hours or days, replacing the need for pills or injections.
How Medication Patches Work
A transdermal patch delivers medication through your skin and into your bloodstream. The drug first passes through the outermost layer of skin, then moves deeper until it reaches tiny blood vessels where it gets absorbed into circulation. This process happens gradually, which is why patches can provide a consistent level of medication over long periods rather than the peaks and valleys you get with a pill.
Not every drug can be delivered this way. The molecule needs to be small enough and have the right chemical properties to pass through skin layers. That’s why patch medications tend to be potent at low doses.
Pain Relief Patches
Several pain medications are available as patches. Fentanyl patches treat severe, chronic pain and are worn for 72 hours (three days) before being replaced. These are prescription-only and reserved for pain that hasn’t responded to other treatments. Buprenorphine patches also treat chronic pain with a similar extended-wear design.
Lidocaine patches work differently. Rather than entering your bloodstream, they numb a specific area of skin and the tissue beneath it. They’re commonly used for nerve pain, such as the lingering pain that can follow a shingles outbreak. You apply them directly over the painful area.
Hormone and Contraceptive Patches
Hormone patches are among the most widely used transdermal medications. Estrogen patches are a common form of hormone replacement therapy for menopause symptoms, typically changed once or twice per week depending on the brand. Testosterone patches are used for hormone replacement in men with low testosterone levels.
The birth control patch contains both estrogen and progestin. You apply a new patch once a week for three weeks in a row, always on the same day of the week, then go patch-free for one week. That cycle then repeats. The patch can be placed on the upper arm, abdomen, buttock, or back.
Smoking Cessation
Nicotine patches are one of the most familiar over-the-counter patches. You wear one for 24 hours, replacing it each morning with a fresh patch on clean skin. If the patch disrupts your sleep or causes vivid dreams, you can remove it at bedtime and apply a new one the next day. Treatment typically lasts 8 to 12 weeks, with the nicotine dose gradually stepping down until you stop using patches entirely.
ADHD Patches
Two stimulant medications for attention deficit hyperactivity disorder come in patch form: methylphenidate and dextroamphetamine. The methylphenidate patch is applied in the morning and worn for up to nine hours, then removed. This gives parents and patients more flexibility over timing compared to oral medications, and it can be a good option for children who have difficulty swallowing pills.
Alzheimer’s Disease Patches
Two medications for Alzheimer’s disease are available as patches: rivastigmine and donepezil. Both work by boosting levels of a brain chemical involved in memory and thinking. The patch form can be especially practical for patients with dementia, since caregivers can apply it once daily without needing the patient to remember or cooperate with taking a pill. It also tends to cause fewer stomach-related side effects than the oral versions.
Mental Health Patches
Selegiline is an antidepressant available as a skin patch for adults with major depression. It works by blocking an enzyme that breaks down mood-related brain chemicals, keeping more of them available. The patch is worn for 24 hours and then replaced. Selegiline is not approved for children under 12.
Asenapine, a medication for schizophrenia, is also available in patch form. This can help with consistent dosing for patients who may struggle with daily pill regimens.
Other Common Patch Medications
- Scopolamine prevents motion sickness and post-surgical nausea. The small patch is placed behind the ear and can be worn for up to three days.
- Clonidine treats high blood pressure. The patch is applied once a week, providing a steady dose that avoids the blood pressure spikes that can happen when oral doses are missed.
- Nitroglycerin prevents chest pain (angina) in people with heart disease. The patch is typically worn for 12 to 14 hours per day, then removed overnight to prevent the body from becoming tolerant to the drug.
- Oxybutynin treats overactive bladder. The patch is applied twice per week, every three to four days, on the same two days each week.
- Granisetron prevents nausea and vomiting caused by chemotherapy. It’s applied 24 to 48 hours before treatment and worn for up to seven days.
- Rotigotine treats Parkinson’s disease and restless legs syndrome. The patch is worn for 24 hours and replaced daily.
Tips for Using Patches Safely
Where you place a patch matters. Choose skin that is clean, dry, flat, and free of hair. Avoid skin folds, areas with cuts or irritation, and spots recently treated with lotions, oils, or moisturizers, as these can interfere with how well the drug absorbs or whether the patch stays put. If you need to remove hair at the site, trim it with scissors rather than shaving, which can irritate the skin.
Rotate your application sites. Using the same spot repeatedly increases the chance of skin irritation. Most patch instructions specify which body areas are appropriate, since absorption rates can vary by location.
Heat is a serious concern with patches. Heating pads, electric blankets, hot tubs, saunas, and even prolonged sun exposure can increase how fast medication absorbs through your skin. With potent drugs like fentanyl, this can be dangerous. The FDA has specifically warned that the scopolamine patch can raise body temperature and reduce sweating, making heat exposure riskier. Keep patches away from direct heat sources.
Disposing of Used Patches
Even after removal, patches still contain residual medication. This is particularly important with opioid patches like fentanyl, where accidental exposure to children or pets can be life-threatening. Fold used patches in half so the sticky sides press together, then wash your hands thoroughly. If you have leftover or unused patches, return them to your pharmacy rather than throwing them in the trash.
When you remove a patch, clean the area with water. Avoid soap or alcohol-based cleansers, which can irritate the skin. An oil-based product like petroleum jelly can help remove leftover adhesive residue.
