To use the Ethinyl Estradiol and Norelgestromin patch safely, you must adhere to a strict application schedule, avoid smoking due to a significantly increased risk of blood clots, and maintain regular check-ups with your healthcare provider. It is also critical to protect the patch from heat and to be aware of how pre-existing medical conditions can impact your suitability for this medication.
This contraceptive patch is an effective tool, but its safety hinges on your proactive management. Success requires understanding not just how to apply it, but also the critical lifestyle choices and health monitoring that must accompany its use.

Core Safety and Application Guidelines
Proper handling and a consistent schedule are the foundation of the patch's effectiveness and your safety.
Proper Application Technique
The patch must be applied to clean, dry, and healthy skin. Ideal locations are the buttock, abdomen, upper outer arm, or upper torso, choosing a place where it won’t be rubbed by tight clothing.
Do not apply the patch to irritated or injured skin. After application, press down firmly for about 10 seconds to ensure the edges are secure.
The Weekly Schedule
You will change your patch once a week on the same day for three consecutive weeks. This is followed by one "patch-free" week.
During your very first cycle of use, it is essential to use a backup, non-hormonal contraceptive method for the first 7 days to ensure you are protected.
Handling and Disposal
Always wash your hands before and after handling the patch to avoid transferring medication. Be careful not to touch your eyes, nose, or mouth after handling it.
When you remove a used patch, fold it in half so the sticky sides press together. Dispose of it safely, keeping it away from children and pets.
Critical Health Precautions and Lifestyle Adjustments
Your daily habits and overall health play a direct role in how safely you can use this medication.
The Absolute Ban on Smoking
Smoking dramatically increases your risk of serious cardiovascular events, including blood clots, heart attack, and stroke, while using this patch. This risk is significant and is the most critical lifestyle precaution to observe.
Heat and Sun Exposure
Do not expose the patch to direct heat sources like heating pads, electric blankets, saunas, or direct, prolonged sunlight. Heat can increase the rate at which your body absorbs the hormones, leading to potential overdose or side effects.
This medication can also make your skin more sensitive to the sun, so use appropriate sun protection.
Monitoring for Potential Side Effects
Be vigilant for signs of fluid retention or increased blood pressure. Report any significant or sudden changes to your doctor.
If you wear contact lenses, pay attention to any changes in your vision or comfort while wearing them.
When to Consult Your Healthcare Provider
Open and continuous communication with your medical team is non-negotiable.
Before You Start the Patch
You must inform your healthcare provider if you have a history of any of the following conditions:
- Abnormal vaginal bleeding
- Blood clots, blood vessel disease, or a clotting disorder
- Heart disease, heart valve problems, or a recent heart attack
- High blood pressure, high cholesterol, or high triglycerides
- History of stroke
- Certain cancers (breast, uterine, cervical, etc.)
- Migraine headaches
- Diabetes with complications
- Liver or kidney disease
- Systemic Lupus Erythematosus (SLE)
During Routine and Emergency Care
Maintain a schedule of regular check-ups, which should include pelvic exams, breast exams, and Pap smears as recommended by your provider.
Always inform any doctor, dentist, or specialist that you are using this patch. It should not be worn during certain medical procedures like an MRI or cardioversion due to the risk of burns from its metallic components.
Understanding the Trade-offs
While effective, the patch carries specific risks that you must weigh with your provider.
The Serious Risk of Blood Clots
The most significant risk associated with this patch is the formation of blood clots (thromboembolism). As stated, this risk is severely amplified by smoking, but can also be influenced by age, obesity, and certain genetic conditions.
Potential for Skin Irritation
Applying the patch to the same spot repeatedly can cause skin irritation. It is important to rotate the application site with each new patch to allow the skin to recover.
Compromised Effectiveness
The patch can become less effective if it is not applied correctly or if it becomes partially or fully detached. Do not use bandages or tape to hold a loose patch in place. If it falls off, consult the medication's instructions or your pharmacist immediately.
Key Actions for Safe and Effective Use
Your primary goal will determine your most important precautions.
- If your primary focus is preventing pregnancy: Meticulous adherence to the weekly schedule and using a backup method during the first week are non-negotiable.
- If your primary focus is minimizing health risks: You must not smoke, and you must attend all scheduled medical check-ups to monitor for cardiovascular changes.
- If your primary focus is day-to-day comfort and ease of use: Carefully rotate application sites to prevent skin irritation and be mindful of activities that could dislodge the patch.
Ultimately, using this medication safely is an active partnership between you and your healthcare provider.
