If you realize you have missed a dose of your nitroglycerin patch, the correct action depends on timing. In most cases, you should apply a new patch as soon as you remember. However, if it is already close to the time for your next scheduled dose, you should skip the missed one and simply continue with your regular schedule.
The guiding principle is to re-establish your medication schedule safely without ever doubling the dose. Applying two patches at once can cause a dangerous drop in blood pressure and other serious side effects.
The Core Principle: Resuming Your Schedule Safely
The goal of any corrective action is to get back on track with your prescribed treatment plan. This requires understanding not just what to do, but why.
When to Apply a Missed Patch
As a general rule, apply the patch as soon as you remember you missed it. This helps maintain a consistent level of medication in your system, which is crucial for preventing angina (chest pain).
The Critical Exception
If it is almost time for your next regularly scheduled patch, do not apply the one you missed. Simply wait and apply your next patch at the normal time. Applying a patch late and then another one on schedule shortly after is too close together.
Why You Must Never Double Up
Applying two patches to "catch up" is extremely dangerous. This introduces a double dose of nitroglycerin into your system, which can cause your blood pressure to drop sharply. This may lead to severe dizziness, fainting, headaches, or more serious cardiovascular events.
Handling Common Patch Issues
Beyond a missed dose, other practical issues can arise. Knowing how to handle them ensures both safety and the medication's effectiveness.
If a Patch Falls Off
A patch that has fallen off should not be reapplied. Immediately replace it with a completely new patch. You can then continue with your original schedule for changing the patch.
Proper Patch Removal and Disposal
When it's time to remove a patch, press down on the center to lift the edges and then gently peel it off.
Because used patches still contain active medication, they must be disposed of carefully. Fold the patch in half with the sticky, medicated side facing inward. Discard it in a place safely out of reach of children and pets.
Caring for Your Skin
After removing the patch, it's a good practice to wash the skin area with soap and water to remove any residual medication.
Understanding the Key Risks
Proper management of your nitroglycerin patch therapy involves being aware of potential risks and taking steps to avoid them.
The Risk of Overmedication
The most immediate risk is from getting too much medication at once, as discussed with doubling up. This leads to hypotension (low blood pressure) and its associated symptoms.
The Risk of Inconsistent Dosing
Conversely, frequently missing doses or allowing patches to fall off without replacement can reduce the medication's ability to prevent angina attacks, leaving you less protected.
Essential Safety Precautions
Always be cautious of dizziness, especially when standing up quickly. Inform any surgeon or dentist that you use a nitroglycerin patch before any procedure. It is also wise to avoid alcohol unless you have explicit approval from your healthcare provider.
Making the Right Choice for Your Situation
Your response to a patch issue should always prioritize safety and consistency.
- If you remembered a missed patch several hours ago: Apply a new patch immediately and continue with your normal schedule from that point.
- If it's almost time for your next scheduled patch: Skip the missed dose entirely and just apply your next patch at its regular time.
- If your patch has fallen off: Discard the old one safely and apply a fresh patch right away.
Following your prescribed schedule consistently is the most effective way to manage your condition and minimize potential risks.

| Almost time for next scheduled dose | Skip the missed dose; apply next patch on schedule. | Prevents applying doses too close together, avoiding overdose. |
| Patch falls off | Discard old patch; apply a new one immediately. | A fallen patch should not be reused for safety and effectiveness. |
| Never | Apply two patches to "catch up." | Doubling the dose can cause a dangerous drop in blood pressure. |
