Proper medication management is important for a smooth surgical procedure and recovery. Not only is preparing for surgery stressful, but understanding which medications to take or avoid can be add to that stress.

In this article, we’ve created a comprehensive guide that’ll help you prepare for your upcoming surgery, which medications are safe to take or should be avoided, and how to manage pain effectively after surgery.

But it's important to note that every situation is different and it's always best for a patient to consult their doctor on how to prepare before heading into the operating room.

Before a Surgical Procedure

Before any surgical procedure, it's imperative that you openly communicate with your healthcare provider about all drugs and supplements you are taking.

Some medications, including over-the-counter drugs or common pain medications, can result in complications such as excessive bleeding, affecting anesthesia, or delayed healing. Your healthcare provider will provide specific instructions, but here are general guidelines to help you prepare:

1. Inform Your Surgeon: Provide a complete list of all current medications that you're taking, including prescriptions, over-the-counter drugs, vitamins, and herbal supplements.
2. Follow Medication Instructions: Your healthcare provider will likely give you instructions on when to stop eating and drinking, which medications to stop taking, and when to take your last dose of certain drugs.
3. Adhere to Fasting Guidelines: For some surgeries, you may need to fast for a specific period before the procedure, which could affect when and how you take your medications.
4. Avoid Certain Supplements: Some supplements, can affect bleeding and should be avoided unless otherwise directed.
5. Stop Smoking and Limit Alcohol: Smoking and alcohol can interfere with anesthesia and healing. Quitting smoking and avoiding alcohol at least a few weeks before surgery can improve your recovery.
6. Stay Hydrated and Eat Healthily: In the days leading up to surgery, eat balanced meals and drink plenty of water to keep your body strong and well-nourished for the healing process.
7. Organize Your Home for Recovery: Prepare your home in advance by arranging a comfortable space for rest, stocking up on essentials, and setting up any necessary medical equipment or aids.
8. Ask Questions and Clarify Concerns: Don’t hesitate to ask your healthcare provider about any concerns, including anesthesia, recovery expectations, or specific instructions related to your medications and overall care.

Drugs That Must Be Avoided: Anti-Inflammatory Medications

Anti-inflammatory medications are commonly used for pain relief, but many should be avoided before surgery due to their blood-thinning effects. Medications such as Ibuprofen (Advil) and Naproxen are nonsteroidal anti-inflammatory drugs (NSAIDs) that can increase complications during surgery.

NSAIDs work by blocking certain substances in the body that cause inflammation and pain, but they also inhibit platelet function, which is important for blood clotting. This can lead to excessive bleeding during or after surgery, complicating the procedure and recovery.

Which Pain Medications Should I Take or Avoid?

Preoperative pain management — such as taking pain killers — is quite common in many patients preparing for upcoming surgeries, but it's important to note that not all pain medications are safe before a surgical procedure. So it’s essential to understand which ones are appropriate.

Medications to Ask Your Surgical Team About:

1. Tylenol (Acetaminophen): Acetaminophen is not an NSAID. In one small study of 13 healthy men, acetaminophen given by IV, not as tablets, reduced platelet clumping for at least 90 minutes, and the effect grew with the dose. The authors noted that earlier studies of usual doses taken by mouth (about 1 gram) had not found this effect, and they wrote that surgical bleeding from acetaminophen "seems unlikely" unless clotting is already impaired, for example by drugs or heavy blood loss. The Tylenol label also says to ask a doctor or pharmacist before use if you take the blood thinner warfarin. Take it before surgery only if your surgical team says to.
2. Vicodin (Hydrocodone): An opioid pain medicine that also contains acetaminophen. The hydrocodone and acetaminophen label warns that profound sedation, slowed breathing, coma, and death can result when it is used with other drugs that slow the central nervous system, and it names general anesthetics in that group. It also lists thrombocytopenia (a low platelet count) as a possible side effect. Tell your surgical team you take it, and ask whether to take it on the day of surgery.
3. Percocet (Oxycodone): An opioid pain medicine combined with acetaminophen. The Percocet label carries the same warning about general anesthetics and lists thrombocytopenia among its reported blood reactions. Tell your surgical team you take it, and ask whether to take it on the day of surgery.
4. Darvocet (Propoxyphene ): Withdrawn from the U.S. market in November 2010. The FDA recommended against its use because the drug "can cause serious toxicity to the heart, even when used at therapeutic doses." If you still have old tablets, talk to your healthcare provider about other pain medicines.

Medications to Avoid Before Surgery:

1. Ibuprofen (Advil, Motrin): Can potentially increase bleeding during surgery due to its effects on platelet function.
2. Naproxen (Aleve): An NSAID that increases bleeding, it should be discontinued at least a week before surgery.
3. Aspirin: A blood thinner that significantly increases bleeding risk. It should be stopped well in advance of your surgery unless otherwise advised by your doctor.
4. Ketorolac (Toradol): A potent NSAID that can significantly increase the possibility of bleeding and is generally avoided before surgery.

Other Medications to Take or Avoid

Beyond pain management medication, other common drugs and supplements may need to be adjusted before surgery.

‍Medications to Ask Your Surgical Team About:

1. Blood Pressure Medications (except ACE inhibitors): The plan depends on the drug, so confirm each one with your healthcare provider. The metoprolol label, for example, says long-term beta blocker therapy "should not be routinely withdrawn prior to major surgery," though it adds that these drugs may raise the risks of general anesthesia. For ACE inhibitors, the lisinopril label warns about low blood pressure during major surgery or anesthesia with drugs that lower blood pressure.
2. Thyroid Medications: Ask your surgical team whether to take your usual dose, and make sure they know you take it. The levothyroxine label says that using it with ketamine, a general anesthetic, "may produce marked hypertension and tachycardia" (a sharp rise in blood pressure and a fast heart rate).
3. Antidepressants: Tell your surgical team which one you take, and ask whether to keep taking it. The sertraline (Zoloft) label says drugs of its type "increase the risk of bleeding events." The label for phenelzine (Nardil), an MAOI antidepressant, says patients taking it "should not undergo elective surgery requiring general anesthesia."
4. Statins: Ask your surgical team. The 2024 AHA/ACC guideline for surgery other than heart surgery reports that large studies found staying on a statin through surgery to be safe, with possible reductions in heart complications. The atorvastatin label, though, says to temporarily stop it in patients with a serious condition at high risk of kidney failure from muscle breakdown, and it lists major surgery as one example.

Medications to Avoid Before Surgery:

1. Plavix (Clopidogrel): A blood thinner that should be stopped well in advance due to the high chance of excessive bleeding during surgery.
2. Coumadin (Warfarin): Another blood thinner that significantly increases bleeding risk. Consult your surgeon for guidance on when to stop.
3. Herbal Supplements: Many herbal supplements can affect bleeding or interact with anesthesia. It’s recommended that you avoid them before surgery.
4. Vitamin E: Known to increase bleeding risk, it should be discontinued before surgery unless your doctor advises otherwise.

Post-Operation: Dealing with Severe Pain

Moderate pain is to be expected for most surgeries, but excessive pain can be a problem for your recovery. Managing pain effectively after surgery is just as important as before surgery. If pain becomes severe, follow these tips:

1. Follow Your Doctor’s Orders: Only take medications as prescribed to manage pain. Overuse or misuse of painkillers can lead to complications or slow down the healing process.
2. Use Tylenol Safely: Tylenol is often recommended for pain after surgery, and it is not an NSAID. Follow the dose your surgical team gives you.
3. Avoid NSAIDs Post-Surgery: Until your surgeon clears you, it’s best to avoid NSAIDs like ibuprofen and naproxen to reduce post-operative recovery times.
4. Consider Opioids Carefully: Opioids like hydrocodone can be used for severe pain, but only under strict medical supervision controlled doses due to their addictive nature and potential side effects.
5. Non-Medication Pain Management: Incorporate techniques like ice packs, elevation, or gentle movement as advised to manage pain and reduce inflammation naturally.

Final Thoughts

Proper medication management is essential to ensure a safe and successful surgical outcome.

Always consult with your healthcare provider about any medications or supplements you take, and adhere strictly to their guidelines before going into the operating room or after leaving it.

By carefully selecting which medications to take or avoid, you can minimize surgical risks and ensure a smoother recovery process.
