8 Most Common Medications Given For Surgery

If you’ve ever prepared for surgery—or helped a loved one through it—you may have found yourself overwhelmed with all the new information flying around. With appointments and various instructions stacking up, it’s a lot to take in. 

And then… There are the medications. Suddenly, you’re handed a list full of names you can’t pronounce, let alone remember what each one does. It’s confusing and more than a little intimidating.

Medications play critical roles in your care before, during, and after surgery. Some are essential for the procedure itself, while others help manage pain, prevent complications, or ease side effects during recovery. Knowing what they are and why they’re used can help make the entire process feel more manageable. 

Let’s walk you through the most common medications used for surgery and explain why they’re given, in clear, everyday language.

Why Surgical Medications Vary From Person to Person

Surgical medications are never one-size-fits-all. Every plan will be tailored to the individual and their needs, ensuring the safest surgery possible and supporting a smoother recovery. 

Your care team, including your surgeon, anesthesia providers, and nurses, tailors medication choices based on several important factors, including:

• Your medical history and current health conditions
• Any prescription and over-the-counter medications
• Any known medication, food, or environmental allergies
• The type, length, and complexity of your surgery
• Your surgeon’s and anesthesia team’s specialized approach
• Expected recovery needs and mobility after surgery

Medication Planning and Safety Review

Before surgery, you’ll meet with members of your care team to review your health history and medications. You may notice that different providers ask you similar questions more than once. But this isn’t a mistake or meant to upset you—different providers asking the same questions is a safety check designed to prevent errors.

Your care team will review:

• Prescription medications, including name, dose, and when you last took them
• Over-the-counter medications, such as aspirin or sleep aids
• Supplements, vitamins, and herbal products, like ginseng or St. John’s wort
• Past surgeries and how you responded to anesthesia
• Any known medication, food, or environmental allergies

Prior Medication or Anesthesia Issues

One of the most critical questions your care team will ask is whether you’ve had any issues with anesthesia or any other medications in the past. 

Your team will want to know if you’ve ever:

• Had nausea, breathing issues, or other reactions 
• Experienced pain medications that did or didn’t work well
• Needed unusually high or low doses of medications

Sharing this information helps guide safer medication choices both during and after surgery.

Lifestyle Factors That Matter

Before surgery, your team will ask you about alcohol use, smoking, or recreational drug use. These questions aren’t to pass judgment on your choices. It’s necessary to review this information because certain substances can alter how medications work, affect healing, or increase overall anesthetic and surgical risks. 

Although some of these questions can feel really personal, being completely honest allows your care team to plan appropriately and keep you safe. Regardless, all personal health information is protected and kept confidential because of the Health Insurance Portability and Accountability Act of 1996 (HIPAA). 

Ultimately, the goal is to safely reach the best possible outcome, and your care team won’t be able to do that without all the necessary information about you and your history.

Medications Used Before Surgery

Anti-anxiety & Procedural Sedation

It’s completely normal to feel nervous before surgery. To help ease anxiety and create a calmer experience, many people receive medications before they ever enter the operating room. In many cases, these medications also cause light sedation, meaning you may feel sleepy or have little memory of the moments right before surgery. 

Common medications include:

• diazepam
• lorazepam
• etomidate
• ketamine
• nitrous oxide

Common side effects you might experience include drowsiness, short-term memory lapses, and slower reaction time. Because of these side effects, you won’t be allowed to drive yourself home after surgery if you receive them. 

Antibiotics

Antibiotics are often given before, during, and sometimes after surgery to help prevent infection. The goal is to ensure that enough of the medication is present in the body at the time surgery begins, which helps reduce the risk of surgical site infections and supports proper healing.

Antibiotics may be given intravenously (through an IV) or by mouth, depending on the type of surgery and the care plan.

Common medications include:

• amoxicillin
• ciprofloxacin
• doxycycline
• vancomycin

Common side effects may include mild nausea, diarrhea, or irritation at the IV site. Your care team selects antibiotics carefully based on the type of surgery and any known medication allergies.

Medications Used During Surgery

Once surgery begins, several types of medications may be used to keep you comfortable, still, and safe throughout the procedure.

Muscle Relaxants (Paralytics)

Muscle relaxants, also called paralytics, are medications used during surgery when general anesthesia is required. They temporarily relax the body’s skeletal muscles, allowing the anesthesia team to place a breathing tube safely and prevent movement during surgery.

These medications are given through an IV and are carefully monitored by the anesthesia team throughout the procedure.

Common medications include:

• rocuronium
• succinylcholine

Common side effects may include muscle soreness after surgery, which typically resolves quickly as the anesthesia wears off.

Anesthesia: The Foundation of Surgical Care

Anesthesia drugs allow surgery to be performed without pain or awareness. There are three main types: general, regional, and local anesthesia.

General Anesthesia

General anesthesia makes you fully unconscious so you have no awareness during surgery, and because of this effect, it’s commonly used for major surgical procedures. It can be given through an IV, inhaled gases, or both. When anesthesia is used in surgery, a breathing tube is usually placed to support your airway.

Common general anesthesia medications include:

• propofol
• sevoflurane
• isoflurane

Common side effects include grogginess afterwards, a sore throat from being intubated, and nausea.

Regional Anesthesia

Regional anesthesia numbs a larger area of the body by blocking the sensation from specific nerves. You may remain awake with regional anesthesia, though additional medications are often given to help you feel relaxed and comfortable during the procedure. It’s commonly used for surgeries involving limbs or childbirth.

Common regional anesthesia medications include:

• bupivacaine
• ropivacaine
• lidocaine

Common forms of regional anesthesia you might have heard of include epidurals, spinal anesthesia, and nerve blocks. One of the benefits of regional anesthesia is that it can significantly reduce pain after surgery and may lessen the need for stronger pain medications during recovery.

Common side effects can include numbness or weakness in the affected area, tingling as sensation returns, and mild soreness at the injection site.

Local Anesthesia

Local anesthesia numbs a small, specific area of the body while you remain fully awake and aware. It’s commonly used for minor procedures, such as placing stitches, removing a mole, or performing small outpatient surgeries. In some cases, local anesthesia may be combined with light sedation to improve comfort.

Common medications include:

• bupivacaine
• lidocaine

Local anesthetics are typically injected directly into the skin or applied topically as a cream or solution. The numbing effect is temporary and wears off gradually after the procedure.

Common side effects may include brief stinging during injection, localized numbness, or mild swelling at the site where the medication was given.

Medications After Surgery

After surgery, you’ll be monitored closely as you wake up and begin recovery. Once you’re stable and awake, you’ll either be discharged home or moved to a hospital room with a whole new list of medications.

Pain Management (Analgesics)

Analgesics, more commonly known as pain medications, are used after surgery to help manage discomfort and support healing. Pain control is individualized, and many recovery plans use a combination of medications rather than relying on just one.

Pain medications may be given through an IV while you’re in the hospital and later transitioned to oral medications once you’re able to eat and drink. This transition helps your care team understand which medications will work best for you at home.

Common medications may include:

• morphine
• hydromorphone
• fentanyl
• ketorolac
• oxycodone
• tramadol
• acetaminophen

Some surgeries limit the use of anti-inflammatory medications due to bleeding or healing concerns, so it’s important to follow your surgeon’s guidance. Pain medications can have side effects, and your care team will help you balance comfort with safety as you recover.

Blood Clot Prevention (Anticoagulants)

After certain surgeries—especially those that limit movement—medications may be prescribed to reduce the risk of blood clots. These medications are called anticoagulants and work by decreasing the blood’s ability to clot.

Anticoagulants may be given as injections under the skin, through an IV, or as oral medications, depending on your surgery and overall risk factors.

Common medications include:

• heparin
• enoxaparin

It’s normal to notice mild bruising at injection sites, particularly around the abdomen. Your care team will provide instructions on how and when these medications should be taken and how long they’re needed during recovery.

Nausea Prevention (Antiemetics) & Other Symptom-Relief Medications

In addition to pain control, other medications are often used to manage common side effects related to surgery or pain medications. These medications help keep you more comfortable as your body heals.

Common symptom-relief medications may include:

• Anti-nausea medications: ondansetron, prochlorperazine
• Acid-reducing medications: famotidine, pantoprazole
• Stool softeners and laxatives: docusate, senna, polyethylene glycol

Constipation is a common side effect after surgery, particularly when opioid pain medications are used. Starting stool softeners early can help prevent discomfort and delays in recovery.

Final Thoughts

Medications are just one part of the surgical experience, but they play a meaningful role in how safe, comfortable, and supported recovery feels. Your surgical medication plan is designed specifically for you. Be sure to follow the discharge instructions provided, and contact your care team if pain isn’t well-controlled or symptoms change. 

It’s completely normal to feel overwhelmed by the amount of information and responsibility that comes with recovering from surgery at home. Medications, symptom changes, and daily routines can feel harder to manage without the constant support and monitoring from healthcare professionals in a hospital setting. 

Knowing when—and how—to ask for additional support after surgery can make recovery feel more manageable. For some individuals and families, working with nurses during recovery at home provides added reassurance.
