The main things to avoid before Botox are alcohol, anti-inflammatory painkillers, and several common supplements, all of which thin your blood and raise the chance of bruising at injection sites. Most of these need to be stopped well before your appointment, not just the day of.
Pain Relievers to Stop 10 to 14 Days Before
This is the one that catches people off guard because the timeline is so long. Aspirin and NSAIDs like ibuprofen (Advil, Motrin) and naproxen (Aleve) interfere with how your blood clots. Weill Cornell Medicine’s pre-procedure guidelines recommend stopping these 10 to 14 days before your appointment, not just a day or two. That means if your Botox is scheduled two weeks from now, you should already be switching to acetaminophen (Tylenol) for any headaches or pain, since acetaminophen doesn’t affect clotting.
If you take a low-dose aspirin daily for heart health, don’t stop it on your own. That’s a conversation with whoever prescribed it. The good news: research on patients receiving Botox while on blood-thinning medication found that hematoma rates were only marginally higher (3% versus 1.8% in patients not on blood thinners), and none of the bruises that did occur were medically serious. So being on a prescribed blood thinner doesn’t automatically disqualify you from getting Botox, but your provider needs to know about it.
Supplements That Thin Your Blood
Several popular supplements act as mild blood thinners, and they need the same 10 to 14 day window as NSAIDs. The list includes:
- Vitamin E
- Fish oil (omega-3 fatty acids)
- Ginkgo biloba
- Ginseng
- Ginger supplements
- Garlic supplements (concentrated capsules, not normal cooking amounts)
These are easy to forget about because people don’t think of vitamins and herbal supplements as “real” medications, but their blood-thinning effects are well documented. If you take a daily multivitamin that contains vitamin E, check the label. A standard multivitamin dose is usually fine, but high-dose standalone vitamin E supplements should be paused.
Alcohol: At Least 24 Hours Before
Alcohol thins the blood and makes bruising more likely. Stanford Medicine’s pre-treatment instructions specify avoiding alcoholic beverages for at least 24 hours before your appointment. Some providers recommend 48 to 72 hours for extra caution, especially if you bruise easily.
This applies to all types of alcohol. Wine, beer, cocktails, and even small amounts can temporarily reduce your blood’s ability to clot. If your appointment is on a Saturday morning, skip Friday night drinks entirely.
Caffeine on the Day Of
Limit caffeine for 24 hours before treatment. Coffee, energy drinks, and caffeinated sodas temporarily raise blood pressure, which makes small blood vessels more fragile and more likely to break when a needle punctures the skin. The effect is temporary, but it overlaps perfectly with the worst possible time: right when you’re getting injected.
If you’re a heavy coffee drinker and worried about a withdrawal headache, a small amount is better than your usual large coffee. The goal is to keep your blood pressure from spiking, not to go through full caffeine withdrawal on treatment day.
High-Sodium Foods
Salty foods cause your body to retain water, which can worsen any swelling at injection sites. While there’s less formal clinical guidance on this compared to alcohol or NSAIDs, many providers recommend cutting back on high-sodium meals for 24 hours before your appointment. That means going easy on processed foods, fast food, soy sauce-heavy dishes, and salty snacks the day before. Staying well hydrated alongside lower sodium intake helps your body manage post-injection swelling more efficiently.
A Quick Timeline to Follow
Pulling it all together, here’s what the pre-Botox timeline looks like:
- 10 to 14 days before: Stop aspirin, ibuprofen, naproxen, and blood-thinning supplements (fish oil, vitamin E, ginkgo, ginseng, ginger, garlic capsules).
- 24 to 48 hours before: No alcohol. Cut back on salty foods and stay hydrated.
- Day of treatment: Skip or significantly reduce caffeine. Stick with acetaminophen if you need a pain reliever.
None of these restrictions are complicated, but the supplement and NSAID timeline is the one most people underestimate. If you realize you took ibuprofen three days ago and your appointment is tomorrow, mention it to your provider. They can assess your individual bruising risk and decide whether to proceed or reschedule.
