Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Describe the allergic reaction you experienced, including the symptoms that occurred.
Certain health conditions, including:
+ Anemia
+ Elevated intracranial pressure (e.g., due to bleeding in the brain or a head injury)
+ Recent heart attack
+ Heart problems
+ Low blood volume (hypovolemia)
Concurrent use of specific medications, such as:
+ Phosphodiesterase type 5 inhibitors: avanafil, riociguat, sildenafil, tadalafil, or vardenafil
+ Ergot alkaloids: dihydroergotamine, ergonovine, ergotamine, or methylergonovine
Other medications, including prescription and over-the-counter drugs, natural products, and vitamins, as this is not an exhaustive list of potential interactions.
To ensure safe use, it is crucial to discuss all your medications and health problems with your doctor and pharmacist. Do not initiate, discontinue, or modify the dose of any medication without first consulting your doctor to confirm that it is safe to do so in conjunction with this medication.
Precautions & Cautions
To minimize the risk of dizziness or fainting, get up slowly from a sitting or lying position. Be cautious when climbing stairs to reduce the risk of falls. Monitor your blood pressure as directed by your healthcare provider.
This medication may interfere with certain laboratory tests. Be sure to notify all your healthcare providers and laboratory personnel that you are taking this drug. Additionally, avoid consuming alcohol while on this medication, as it may interact with the drug.
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects. Taking more than the prescribed dose or frequency can lead to tolerance, reducing the medication's effectiveness. If you find that the drug is no longer working as well, consult your doctor. Do not exceed the recommended dose.
If you are pregnant, plan to become pregnant, or are breastfeeding, discuss the potential benefits and risks with your doctor to ensure the best decision for you and your baby.
Overdose Information
Overdose Symptoms:
- Severe throbbing headache
- Flushing
- Perspiration
- Nausea and vomiting
- Dizziness
- Syncope (fainting)
- Tachycardia (fast heart rate)
- Hypotension (low blood pressure)
- Methemoglobinemia (rare, but serious, causing bluish skin, lips, and nail beds, shortness of breath, fatigue)
What to Do:
Seek immediate medical attention. Call 911 or your local emergency number. For advice, call a poison control center at 1-800-222-1222.
Drug Interactions
Contraindicated Interactions
- Phosphodiesterase-5 (PDE5) inhibitors (e.g., sildenafil, tadalafil, vardenafil, avanafil) - concurrent use can cause profound and prolonged hypotension, syncope, or myocardial ischemia/infarction.
- Riociguat (soluble guanylate cyclase stimulator) - concurrent use can cause severe hypotension.
Major Interactions
- Other vasodilators (e.g., hydralazine, minoxidil, alpha-blockers) - additive hypotensive effects.
- Antihypertensive agents (e.g., beta-blockers, calcium channel blockers, ACE inhibitors, ARBs, diuretics) - additive hypotensive effects.
- Alcohol - may enhance hypotensive effects and cause orthostatic hypotension.
Moderate Interactions
- Aspirin - may increase nitroglycerin levels and effects.
- Heparin - may decrease the anticoagulant effect of heparin (requires close monitoring of aPTT).
Minor Interactions
- Dihydroergotamine - may increase the bioavailability of dihydroergotamine and its vasoconstrictive effects.
Monitoring
Baseline Monitoring
Rationale: To establish baseline and assess for hypotension before administration.
Timing: Before first dose, especially in patients prone to hypotension.
Rationale: To establish baseline and assess for reflex tachycardia.
Timing: Before first dose.
Routine Monitoring
Frequency: Immediately after administration, then as needed based on patient response and symptoms.
Target: Maintain within patient's normal limits, avoid symptomatic hypotension.
Action Threshold: Systolic BP < 90 mmHg or symptomatic hypotension (dizziness, syncope).
Frequency: Immediately after administration, then as needed.
Target: Maintain within patient's normal limits, avoid significant tachycardia.
Action Threshold: Significant reflex tachycardia (>100 bpm or >20 bpm increase from baseline).
Frequency: Continuously after administration.
Target: Complete or significant relief of chest pain.
Action Threshold: Persistent or worsening chest pain after 3 doses; seek emergency medical attention.
Symptom Monitoring
- Headache (common side effect, often indicates drug activity)
- Dizziness or lightheadedness (sign of hypotension)
- Flushing
- Nausea
- Palpitations
- Blurred vision
Special Patient Groups
Pregnancy
Category C. Animal studies have shown adverse effects, but there are no adequate and well-controlled studies in pregnant women. Use only if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
It is not known whether nitroglycerin is excreted in human milk. Caution should be exercised when nitroglycerin is administered to a nursing woman. Consider the benefits of breastfeeding, the risk of infant exposure, and the risk of untreated maternal condition.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established. Not recommended for use in children.
Geriatric Use
Elderly patients may be more susceptible to the hypotensive effects of nitrates and may experience increased dizziness and lightheadedness. Use with caution, starting with the lowest effective dose and monitoring blood pressure closely.
Clinical Information
Clinical Pearls
- Instruct patients to sit down when taking nitroglycerin to minimize dizziness or fainting due to hypotension.
- If chest pain is not relieved after the first dose, the patient should call 911 or seek immediate medical attention while continuing to take up to 2 more doses at 5-minute intervals.
- Patients should be advised that a mild headache is a common side effect and often indicates the drug is working. This headache can be managed with mild analgesics.
- Nitroglycerin tablets are sensitive to light, heat, and moisture. Proper storage in the original amber glass bottle, tightly capped, is crucial for maintaining potency.
- Tolerance to the effects of nitroglycerin can develop with continuous or frequent use. This is less common with intermittent sublingual use for acute angina.
- The tingling or burning sensation under the tongue is not a reliable indicator of potency; lack of sensation does not mean the tablet is ineffective.
Alternative Therapies
- Long-acting nitrates (e.g., isosorbide mononitrate, isosorbide dinitrate) for angina prophylaxis.
- Beta-blockers (e.g., metoprolol, atenolol) for angina prophylaxis.
- Calcium channel blockers (e.g., amlodipine, diltiazem, verapamil) for angina prophylaxis.
- Ranolazine (for chronic angina).
