In general, acetaminophen (paracetamol, Tylenol) is usually considered acceptable before Botox or filler, while aspirin and anti-inflammatory painkillers such as ibuprofen or naproxen may increase bruising. At Re:berry Hongdae, we ask you to check with the clinic first and never to stop a prescribed medication without talking to the doctor who prescribed it.

Why do painkillers matter before injections?
Botox and filler are delivered with fine needles or cannulas, and every injection can nick a tiny blood vessel. Medications that affect platelets or blood clotting make it easier for blood to leak under the skin, which can increase bruising and swelling. Bruises are not dangerous in most cases, but they can be visible for a week, which matters if you have an event or are traveling.
Which painkillers are usually fine?
Acetaminophen, also called paracetamol or sold as Tylenol, does not significantly affect platelets, so it is usually considered acceptable before and after injections for headaches or general discomfort. Always follow the dose on the label.
Which painkillers may increase bruising?
- Aspirin: Affects platelets for several days after a dose.
- Ibuprofen (Advil, Motrin) and naproxen: Non-steroidal anti-inflammatory drugs (NSAIDs) that can increase bleeding tendency.
- Combination cold or pain products: Some contain aspirin or NSAIDs, so check the ingredients.
Many clinics suggest avoiding these for several days before treatment if they are taken occasionally and not for a medical reason. Ask Re:berry Hongdae when you book about timing for your specific treatment.
What if I take aspirin or blood thinners for a medical reason?
Do not stop prescribed aspirin, anticoagulants or antiplatelet drugs on your own. These protect against serious conditions such as clots and stroke. Tell the doctor at consultation; treatment can often still go ahead with extra care, or the plan may be adjusted.
Supplements and alcohol
Fish oil, vitamin E, ginkgo, garlic supplements and high-dose turmeric may also increase bruising. Alcohol the night before can do the same. Bring a list of everything you take. For more preparation tips, see what to avoid before a skin treatment and how to reduce bruising.
What about pain during treatment?
Most discomfort is managed with numbing cream, ice and fine needles, and many fillers contain lidocaine. If you are worried about pain, mention it at consultation. See Botox for wrinkles and Juvederm filler for what to expect.

Related questions
Can I take ibuprofen after filler for swelling?
Many clinicians prefer acetaminophen for discomfort in the first days after filler, because ibuprofen may increase bruising. Cold compresses and keeping your head raised also help with swelling. Check with the clinic before taking anything, especially if swelling is significant or painful, which should be assessed.
How many days before Botox should I stop aspirin?
If you take aspirin occasionally for pain, not for a medical condition, clinics often suggest avoiding it for about a week before injections, because its effect on platelets lasts several days. If aspirin is prescribed, do not stop it without your prescribing doctor's advice. Tell the clinic at booking.
Can I take antihistamines before treatment?
Antihistamines do not usually increase bruising and are often acceptable. However, tell the clinic about any allergy medication, as allergies may be relevant to products used during treatment. The doctor will review all your medications at consultation before injections are performed.
