Pharmacist tips for Nitro-Bid (nitroglycerin)
- Nitro-Bid (nitroglycerin) is only for preventing chest pain; it doesn't treat chest pain that has already started. Your cardiologist might also prescribe forms of nitroglycerin, like the spray or sublingual tablet to treat chest pain quickly.
- Nitro-Bid (nitroglycerin) commonly causes daily headaches. Headaches usually mean that the medication is working. If they become too bothersome, discuss with your prescriber the best way to manage them.
- Nitro-Bid (nitroglycerin) can lower your blood pressure, which can lead to dizziness, lightheadedness, or fainting. Avoid alcohol because it can worsen dizziness and lower your blood pressure more.
- Make sure to tell your care team about all of the medications you take because Nitro-Bid (nitroglycerin) interacts with certain medications. For example taking PDE-5 inhibitors, like sildenafil (Viagra) and tadalafil (Cialis), with Nitro-Bid (nitroglycerin) can cause your blood pressure to become dangerously low.
- Most people apply Nitro-Bid (nitroglycerin) on their chest, but you can choose a different area if you prefer. Just make sure it's a spot you can easily reach, as you might need to cover the site with tape or plastic wrap and later wipe it off.
How to apply Nitro-Bid (nitroglycerin)
- Measure your dose using the paper applicator included with the medication. Lay the applicator flat, printed side down. Squeeze the ointment onto the applicator, then place it ointment-side down on the application site.
- Spread the ointment using the paper applicator lightly. Don't rub or massage it into the skin. Cover the area with medication to match the size of the applicator, which measures about 3½ inches by 2¼ inches. A larger area can be used, if needed.
- Tape the applicator onto your skin so it stays in place and doesn't move or fall off. Completely cover the applicator. To avoid staining clothing, you can wrap it with plastic kitchen wrap.
- You'll need to take the applicator off and wipe the medication off for 10 to 12 hours each day. It's recommended to do this in the evening and overnight. Removing Nitro-Bid (nitroglycerin) allows your body to have a "nitrate-free" period. This is so you don't build a tolerance to the medication. Otherwise, it might not work as well to prevent chest pain.
Common questions about Nitro-Bid (nitroglycerin)
Chest pain can occur when there isn't enough blood flowing to the heart, a condition known as angina. Nitrates like Nitro-Bid (nitroglycerin) raise the levels of a chemical called nitric oxide (NO) in blood vessels. NO relaxes and opens up these blood vessels, allowing blood to flow better which prevents chest pain.
Studies show the effects of Nitro-Bid (nitroglycerin) can last for up to 7 hours after a single application. If you feel that the medication isn't lasting long enough, don't take extra doses. Instead, contact your prescriber because you might need a different medication.
Yes, Nitro-Bid (nitroglycerin) can be safe as long as it's taken as prescribed. Taking too much of the medication can put you at a higher risk for side effects like headache, low blood pressure, dizziness, and flushing. Speak to our prescriber if you experience any of the symptoms above.
Apply Nitro-Bid (nitroglycerin) using the dose measuring paper applicator that comes with the medication. It should be spread on the skin, not rubbed in. Spread the ointment on the skin to match the size of the applicator (3½ inches by 2¼ inches). Ask your care team if you have questions about how to apply Nitro-Bid (nitroglycerin).
No, Nitro-Bid (nitroglycerin) isn't a beta blocker. Instead, it's a nitrate. But beta blockers are typically used for treating angina too. So you might need to take both Nitro-Bid (nitroglycerin) and a beta blocker together.
No, Nitro-Bid (nitroglycerin) is only available by a prescription from a healthcare professional (HCP).
Nitrates like Nitro-Bid (nitroglycerin) work by opening blood vessels in the heart. But they also open the blood vessels in the brain too, which can cause headaches. Talk to your prescriber if you experience headaches that are too bothersome or severe to handle. They might recommend tips and tricks to treat them, or might consider switching you to a different medication.
It varies from person to person. Although it takes about an hour for Nitro-Bid (nitroglycerin) to reach steady levels in your blood, studies have shown that it can start working within 30 minutes. If you're having active chest pain, it's important to remember that Nitro-Bid (nitroglycerin) isn't the best medication to treat it. There are faster-acting forms of nitroglycerin, like the spray or sublingual tablet, that work within 5 minutes.

Risks and warnings for Nitro-Bid (nitroglycerin)
Nitro-Bid (nitroglycerin) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Tolerance
- Risk factors: Use of long-acting nitrates | Taking too many doses of Nitro-Bid (nitroglycerin)
Your body can get used to Nitro-Bid (nitroglycerin) over time. When this happens, the same amount of medication might no longer work as well as it used to. This is called tolerance or tachyphylaxis. Tolerance to Nitro-Bid (nitroglycerin) is more likely to happen if you’ve taken longer-acting forms of nitrates (e.g., isosorbide mononitrate (Monoket) or isosorbide dinitrate (Isordil)). When you develop tolerance, taking a higher dose of medication won't help it work better. Because of this risk, make sure to take Nitro-Bid (nitroglycerin) at the prescribed dose and talk to your prescriber if you notice worsening chest pain. To prevent tolerance, your prescriber will ask you to schedule a nitrate-free period (about 10-12 hours when you're not taking Nitro-Bid (nitroglycerin)).
Low blood pressure
- Risk factors: Taking Nitro-Bid (nitroglycerin) while standing | Certain heart problems | Dehydration | Use of erectile dysfunction medications | Use of blood pressure-lowering medications | Alcohol use
Nitro-Bid (nitroglycerin) can cause your blood pressure to drop too much, which can make you feel dizzy, tired, or lightheaded. When you use Nitro-Bid (nitroglycerin), make sure to sit down for the first few minutes to avoid dizziness or fainting. Change positions slowly until your body is used to the medication. Get emergency help if you feel like you're going to pass out in addition to having an irregular heartbeat, nausea, vomiting, weakness, changes in vision, sweating, cold and clammy skin, or worse chest pain.
Worsening chest pain
- Risk factors: Hypertrophic cardiomyopathy
Although rare, taking Nitro-Bid (nitroglycerin) can worsen chest pain that's caused by a heart problem called hypertrophic cardiomyopathy. This is a condition where your heart muscles are too thick and can't pump blood as well. If you’ve been diagnosed with hypertrophic cardiomyopathy, check with your prescriber to make sure that this medication is right for you. If you take a Nitro-Bid (nitroglycerin) dose and it worsens your chest pain, get emergency help right away.
Headache
- Risk factors: First starting Nitro-Bid (nitroglycerin) | Higher doses of Nitro-Bid (nitroglycerin) | Drinking alcohol
Some people experience daily headaches after starting Nitro-Bid (nitroglycerin). Sometimes, these headaches happen as you go from a sitting or lying position to a standing position. The headaches often ease or go away after your body gets used to the medication. If the headaches are bothersome, talk to your healthcare professional about other options.
Nitro-Bid (nitroglycerin) dosage
Typical dosage for Nitro-Bid (nitroglycerin)
The typical starting dose is ½ an inch twice per day. Your prescriber will adjust the dose based on how well you respond to the medication.
