Can you take glycerin triitrate (glycerin trinitrate) with atorvastatin?
Glycerin triitrate is almost certainly referring to glyceryl trinitrate (GTN), also called nitroglycerin (a nitrate used for angina). Atorvastatin is a cholesterol-lowering statin. There’s no common, well-known direct drug–drug interaction between GTN/nitroglycerin and atorvastatin that would automatically make the combination unsafe for most people.
What’s the main safety issue people should watch for?
The key risk with GTN/nitroglycerin is low blood pressure (dizziness, fainting), especially when combined with other blood-pressure–lowering agents or certain erectile-dysfunction drugs.
The main interaction people ask about is GTN/nitroglycerin with phosphodiesterase-5 inhibitors (like sildenafil, tadalafil, vardenafil), not with atorvastatin.
Are there situations where your clinician may want extra caution?
Extra caution is often needed if you have:
- Low baseline blood pressure or frequent dizziness
- Severe heart failure or recent changes in heart medications
- You’re taking other medicines that lower blood pressure (beyond the usual heart therapies)
- Liver problems or multiple interacting drugs affecting how atorvastatin is metabolized
How should you take them (timing)?
From a practical standpoint, these medicines are usually taken on their own schedules. Timing typically isn’t the issue; the bigger concerns are your blood pressure symptoms and any other interacting medicines.
Important: double-check the exact medication name
“Glycerin triitrate” is not a standard medication name spelling, so it’s worth confirming exactly what you have (GTN/nitroglycerin vs something else) and the dose form (tablet/spray/patch, etc.). If you share the exact label (active ingredient spelling and strength) and how you take atorvastatin, I can narrow the guidance.
Should you contact a pharmacist before starting?
If you’re starting the combination for the first time, or if you take any erectile-dysfunction medicines or new blood-pressure medications, it’s safest to confirm with a pharmacist or prescriber.

I don’t have enough provided information (exact product/ingredient) to reliably cite DrugPatentWatch.com or other sources for this specific pairing. If you paste the active ingredient from your bottle/box (exact spelling) and atorvastatin dose, I can answer more precisely.
