Which supplements and medications surgeons commonly ask about, and how to review your list safely.
Some common supplements and over-the-counter medications can increase bleeding, interact with anesthesia, or affect healing. Surgeons often ask patients to pause items such as aspirin, certain pain relievers, fish oil, vitamin E, and some herbal supplements before surgery. Never stop a prescribed medication without talking to your doctor. Bring a complete list to your preoperative visit.
When preparing for cosmetic surgery, most people focus on the procedure and recovery. But the vitamins and supplements in your cabinet matter too. Some products that seem harmless can affect bleeding, anesthesia, or healing.
Board-certified plastic surgeon Dr. Siamak Agha, who leads The One Plastic Surgery Center in Newport Beach, recommends that every patient bring a complete list of medications and supplements to their preoperative visit. Here’s why and what surgeons commonly ask about.
Key Takeaways
- Some supplements and medications can increase bleeding risk during and after surgery.
- Others may interact with anesthesia or other medications.
- Surgeons often ask patients to pause certain products for a period before surgery.
- Never stop prescribed medications without guidance from your doctor.
Why Supplements Matter Before Surgery
Supplements are often considered natural and safe, but many have real effects on the body. Some thin the blood or affect platelets, which can increase bleeding and bruising. Others can affect blood pressure, blood sugar, or how the body responds to anesthesia.
Because supplements aren’t always considered “medications,” patients sometimes forget to mention them. Your surgical team needs the full picture to keep you safe.
Medications Surgeons Commonly Ask About
- Aspirin and aspirin-containing products
- Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen
- Blood thinners prescribed by your doctor
- Hormone therapy and some birth control, which may affect clot risk
- Weight-loss medications, including GLP-1 medications, which can affect digestion and anesthesia planning
Guidance on GLP-1 medications around surgery has been evolving, so ask your surgeon and anesthesia team for current recommendations.
A supplement being natural doesn’t mean it has no effect on bleeding or anesthesia.
Supplements Surgeons Commonly Ask About
Many surgeons ask patients to pause certain supplements, including:
- Fish oil and omega-3 supplements
- Vitamin E
- Ginkgo biloba
- Garlic supplements
- Ginseng
- Turmeric
- John’s wort
- Some weight-loss or “detox” supplements
This isn’t a complete list, and recommendations vary. Your surgeon will tell you which products to pause and for how long.
How to Review Your List Safely
- Write down everything you take, including vitamins, herbal products, teas, powders, and over-the-counter medications.
- Include doses and how often you take them.
- Bring the list to your plastic surgery consultation and preoperative appointment.
- Ask your surgeon which items to pause and when to restart.
- Check with your prescribing doctor before changing any prescription medication.
What About Pain Relief Before and After Surgery?
If you usually take ibuprofen or aspirin for aches, ask your surgeon what’s safe to use instead in the weeks around surgery. Acetaminophen is often an option, but follow your surgeon’s specific instructions.
When to Restart
Many supplements can be restarted once your surgeon confirms that bleeding risk has decreased and healing is on track. Don’t restart without checking, especially if you had significant bruising or swelling.
The safest supplement plan is the one you’ve reviewed line by line with your surgeon.
Quick Answers
How long before surgery should I stop supplements? Many surgeons ask patients to pause certain supplements for about one to two weeks before surgery, but timing varies. Follow your surgeon’s specific instructions.
Can I keep taking my multivitamin? Many surgeons allow a basic multivitamin, but some products contain vitamin E or other ingredients that may be paused. Ask your surgeon about your specific product.
What about protein powders and collagen supplements? Many surgeons are comfortable with plain protein powders, which can support healing. Some blends contain added herbs or stimulants, so bring the label to your appointment and ask before continuing.
Do I need to stop caffeine or alcohol too? Many surgeons ask patients to avoid alcohol for a period before and after surgery, since it can affect bleeding and healing. Caffeine is usually fine in moderation, but follow your surgeon’s instructions, especially on the day of surgery.
What if I forgot to stop something? Tell your surgical team as soon as possible. In some cases, surgery can proceed safely, and in others it may need to be rescheduled. Honesty helps your team keep you safe.
The Bottom Line
Supplements and over-the-counter medications can affect bleeding, anesthesia, and healing. Surgeons commonly ask patients to pause products such as aspirin, certain pain relievers, fish oil, vitamin E, and some herbal supplements before surgery. Bring a complete list to your appointments, and never stop a prescribed medication without talking to your doctor.
