Pharmacist tips for GoNitro (nitroglycerin)
- Keep packets of GoNitro (nitroglycerin) with you at all times, since chest pain can happen at any time or when you aren't expecting it.
- To use a packet of GoNitro (nitroglycerin), tear it open along the red arrows and pour all of the powder under your tongue. Close your mouth and breathe through your nose and try not to swallow until the powder is fully dissolved. To make sure the medication fully absorbs, don't spit or rinse your mouth for 5 minutes after dosing.
- Don't use more than 3 packets within 15 minutes. Call 911 or go to the hospital if you're still having chest pain after 3 packets or if the pain is different from usual.
- GoNitro (nitroglycerin) can cause low blood pressure, which can lead to dizziness, lightheadedness, or fainting. Sit down before and after taking this medication to avoid side effects and also to rest your heart if you are already having chest pain.
- You may get a headache, especially after the first few times taking GoNitro (nitroglycerin). This is a known side effect and usually goes away with time.
- Erectile dysfunction medications (Viagra, Levitra, Cialis) cannot be taken while you are on GoNitro (nitroglycerin). It can cause your blood pressure to become dangerously low. If you are having chest pain but recently took an erectile dysfunction medication, it's best to get emergency help right away and avoid taking GoNitro (nitroglycerin) unless a healthcare provider says it's safe to do so.
Common questions about GoNitro (nitroglycerin)
GoNitro (nitroglycerin) doesn't stop heart attacks. It's often given by healthcare providers when someone is having a heart attack; however it only helps with the pain symptom and doesn't prevent heart damage or death from a heart attack. Only take GoNitro (nitroglycerin) as instructed. If you are having heart-related chest pain (angina) that is different or worse than usual, or if it hasn't gotten better after 3 doses of GoNitro (nitroglycerin), get emergency medical help right away because you may be experiencing something more serious.
GoNitro (nitroglycerin) and erectile dysfunction medications (Viagra, Levitra, Cialis) work on a similar pathway in the body to relax blood vessels. This is why it's dangerous to combine the two classes of medications - your blood vessels may become too relaxed, causing very low blood pressure. GoNitro (nitroglycerin) doesn't help with erectile dysfunction because not enough of it reaches the penis. There has been research into nitroglycerin formulations that can be put directly on the penis, however none have been FDA-approved for that use.
There are no clear guidelines for how often you can take GoNitro (nitroglycerin). However, if you are having chest pain that doesn't go away after 3 packets within 15 minutes, get emergency medical help right away because you may be experiencing a serious problem with your heart. If you use GoNitro (nitroglycerin) throughout the day for many days in a row, you could develop tolerance, which means that the same dose may not work as well for you after a while. Tell your provider if your chest pain is happening more often because you may benefit from longer-acting medications to prevent the chest pain.
When you are taking aspirin and GoNitro (nitroglycerin) on a routine basis, the order of these medications doesn't really matter. However, if you or someone you know may be having a heart attack, aspirin should be given first as long as they're not allergic to it. This is because aspirin is the most important medication to help someone survive a heart attack. GoNitro (nitroglycerin) helps with the pain symptoms but doesn't prevent heart damage or death from a heart attack.

Risks and warnings for GoNitro (nitroglycerin)
GoNitro (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
Your body can get used to GoNitro (nitroglycerin), which means the same amount of medication may no longer work as well as it used to. This is called tolerance and it cannot be fixed by raising the dose of the medication. Tolerance is more likely to happen if you take other, longer-acting forms of nitroglycerin or nitroglycerin-like medications (like isosorbide mononitrate or dinitrate). Still, make sure to take GoNitro (nitroglycerin) only when you need it and talk to your provider if you notice your chest pain starts to get worse.
Low blood pressure
- Risk factors: Taking GoNitro (nitroglycerin) while standing | Problems with the outside of the heart or heart valves | Dehydration | Use of erectile dysfunction medications | Use of blood pressure-lowering medications | Alcohol use
GoNitro (nitroglycerin) can cause dangerously low blood pressure in some people. When you take GoNitro (nitroglycerin), 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 like you are going to pass out and are experiencing an irregular heartbeat, nausea, vomiting, weakness, changes in vision, sweating, cold and clammy skin, or if your chest pain gets worse.
Worse chest pain
- Risk factors: Hypertrophic obstructive cardiomyopathy
In some rare cases, taking GoNitro (nitroglycerin) can cause your chest pain to get worse. Check with your provider to make sure that GoNitro (nitroglycerin) is right for you, especially if you have been diagnosed with hypertrophic obstructive cardiomyopathy, a condition where your heart muscles become too thick and don't pump as well. Contact your provider right away if GoNitro (nitroglycerin) makes your chest pain worse.
Headache
GoNitro (nitroglycerin) can cause headaches, especially when you first start taking this medication or if you take higher doses. The headaches can get pretty bad, but should get better after you've used GoNitro (nitroglycerin) for a few times and your body gets used to it. If the headaches are causing you too many problems, talk to your healthcare provider about other options.
