Medication Guidance for Dental Surgery in IgA Nephropathy Patients - Internal Medicine

Should I consult about stopping medication before a dental clinic minor surgery?


Hello Doctor, I have IgA nephropathy, with an eGFR of approximately 90 and a UPCR of about 0.3.
Recently, I have a cyst on my gums, and I need to undergo an apicoectomy (local anesthesia, approximately 1 to 2 hours).
Currently, I am taking the following medications/supplements: Approvel 150 mg (once every morning), Pentoxifylline 400 mg (200 mg in the morning, 200 mg in the evening), MACALOL (Vitamin D) 0.25 µg (once every evening), and fish oil (EPA 1152 mg, DHA 768 mg).
I would like to ask if there are any medications I should discontinue.
Thank you.

Hello: It is actually recommended to consult the dentist who will be handling your case! In theory, the medications that need to be stopped before surgery are anticoagulants.
Fish oil may have some mild anticoagulant effects, but they are not strong.
If you are really concerned, you might consider stopping fish oil a few days prior to the procedure.
The other three medications do not have any impact.

More Info


When preparing for dental surgery, particularly in patients with IgA nephropathy, it is crucial to consider the medications currently being taken, as some may need to be paused to ensure a safe surgical experience. In your case, you are taking Approvel (an antihypertensive), Pentoxifylline (used for improving blood flow), MACALOL (Vitamin D), and fish oil supplements.
Firstly, it is essential to consult with your dentist or oral surgeon about your specific medications. They will have the most accurate information regarding how these medications might interact with the anesthesia or the surgical procedure itself. However, based on general medical knowledge, here are some insights regarding the medications you mentioned:
1. Approvel (Azilsartan): This medication is an angiotensin II receptor blocker (ARB) used to manage high blood pressure. It is generally safe to continue taking this medication unless your dentist advises otherwise. Maintaining stable blood pressure is important during surgery.

2. Pentoxifylline: This medication is used to improve blood flow and may have mild anticoagulant effects. While it is not a strong blood thinner, it may be prudent to discuss with your dentist whether to pause this medication for a few days before the surgery to minimize any potential bleeding risks.

3. MACALOL (Vitamin D): Vitamin D is essential for bone health and does not typically pose any risks during dental procedures. It is generally safe to continue taking this supplement.

4. Fish Oil: Fish oil can have mild blood-thinning effects due to its omega-3 fatty acids. While the anticoagulant effect is not as pronounced as with other medications, it may be advisable to stop taking fish oil a few days before the surgery to reduce the risk of excessive bleeding.

In summary, it may be wise to consider pausing Pentoxifylline and fish oil before your dental surgery, but you should confirm this with your healthcare provider. They can provide personalized advice based on your overall health status and the specifics of your surgery.

Additionally, given your IgA nephropathy with an estimated GFR of around 90, you are in a relatively stable condition regarding kidney function. However, it is essential to monitor your renal function closely, especially when undergoing any surgical procedures. Ensure that your dental team is aware of your kidney condition, as they may need to adjust their approach based on your health status.

Lastly, post-surgery, keep an eye on any signs of complications, such as excessive bleeding or infection, and report any unusual symptoms to your healthcare provider promptly. Following these guidelines can help ensure a safe and successful dental procedure while managing your underlying health conditions effectively.
