In the event of a suspected nitroglycerin patch overdose, your first actions must be immediate and decisive. If possible, safely remove the patch from the skin and call for emergency medical help without delay. The severity of the symptoms will determine whether to call 911 or a poison control center.
A nitroglycerin overdose is a serious medical emergency that occurs when the body is exposed to too much of the medication. Recognizing the symptoms and knowing exactly who to call is critical for a safe and rapid response.
Recognizing the Symptoms of an Overdose
An overdose disrupts the cardiovascular system, leading to a range of symptoms from mild to life-threatening. Knowing what to look for is the first step in a proper response.
Initial Warning Signs
The most common initial symptoms are a direct result of excessive blood vessel dilation. These can include a severe headache, dizziness or lightheadedness, confusion, and feelings of nausea or instances of vomiting.
Severe, Critical Symptoms
The situation becomes critical if more severe symptoms appear. These are signs of a profound medical emergency and require an immediate 911 call. Watch for fainting, collapse, seizures, or difficulty breathing.
Understanding How an Overdose Occurs
An overdose isn't always intentional. It often happens accidentally through incorrect usage of the patch, which is why understanding the causes is key to prevention.
Dermal Overexposure
The most frequent cause of an overdose is applying too many patches at once or leaving a single patch on for longer than the prescribed time. This leads to a continuous, excessive absorption of the medication through the skin.
Accidental Ingestion
A particularly dangerous scenario occurs if a patch is chewed or swallowed, often by a child or a confused adult. This delivers a massive, rapid dose of nitroglycerin to the body and is a critical emergency.
Crucial Steps to Take Immediately
Your response should be guided by the severity of the victim's condition.
If Severe Symptoms are Present
If the person collapses, has a seizure, is unconscious, or is struggling to breathe, call 911 or your local emergency services immediately. This is a life-threatening situation.
For Milder Symptoms or Uncertainty
If the person is conscious but experiencing symptoms like a severe headache, dizziness, or confusion, call a poison control center right away. In the U.S., the number is 800-222-1222. They will provide expert guidance.
While Waiting for Help
If it is safe to do so, carefully remove the patch from the person's skin to stop any further absorption of the medication. If the patch was swallowed, try to remove any remaining pieces from the mouth.
Preventing Accidental Overdose
The best way to handle an overdose is to prevent it from ever happening. Adhering to safety protocols is non-negotiable when handling this potent medication.
Follow Prescription Instructions Precisely
Never use more patches than prescribed or wear them for longer than your doctor has instructed. Follow a strict schedule for application and removal.
Disclose All Medications to Your Doctor
Nitroglycerin can have dangerous interactions with other drugs, especially PDE-5 inhibitors like sildenafil (Viagra). Ensure your healthcare provider knows every medication and supplement you are taking.
Ensure Safe Storage and Disposal
Keep nitroglycerin patches out of reach of children and pets. When you dispose of a used patch, fold it in half with the sticky sides together to prevent accidental exposure.
Making the Right Call in an Emergency
In a moment of crisis, a clear plan of action is essential.
- If the person has collapsed, is having a seizure, or is struggling to breathe: Immediately call 911 or your local emergency services.
- If the person is conscious but showing other overdose symptoms: Contact a poison control center at 800-222-1222 for expert guidance.
- If you are ever in doubt about the severity: Treat it as a serious emergency and call for immediate medical help.
Being prepared and acting decisively is the most effective way to manage this medical emergency.
