Your injector needs information you might not think to volunteer. Most first-time filler patients arrive focused on what they want—more volume in the cheeks, softer nasolabial folds, fuller lips—without understanding that undisclosed health history, current medications, and recent dental procedures can turn a safe appointment into a preventable complication.
The consultation is a two-way process. Yes, you're evaluating the provider. But the provider is also building a clinical picture of you. The more accurate and complete that picture, the safer your treatment.
Medications That Change Everything
The most consequential category of pre-appointment disclosure is current medications and supplements. Several common ones meaningfully increase your risk of bruising, affect healing, or create contraindications that most patients never anticipate.
Blood thinners and anticoagulants. Warfarin, Eliquis, Xarelto, Plavix, and similar medications are absolute disclosures. Fillers involve needles passing through tissue, and patients on anticoagulants can develop significant bruising or hematomas that wouldn't occur in anticoagulated patients. Your injector may need to consult with your prescribing physician before proceeding, or time the appointment around your medication schedule. Never stop anticoagulants before an aesthetic appointment without explicit guidance from your cardiologist or primary care provider.
NSAIDs, aspirin, and common pain relievers. Ibuprofen (Advil, Motrin), naproxen (Aleve), and aspirin inhibit platelet function and increase bruising risk. These aren't prescription medications—they're over-the-counter drugs most people don't think to mention. Providers typically ask patients to avoid NSAIDs for 7-10 days before treatment, but only if the patient discloses they're taking them.
Supplements with blood-thinning effects. Fish oil, vitamin E, garlic supplements, ginkgo biloba, ginseng, turmeric capsules, and St. John's Wort all have antiplatelet properties. These feel innocuous because they're "natural," but they can significantly increase bruising. Your injector should know what you're taking.
Herpes medications and antiviral history. Hyaluronic acid fillers can trigger cold sore outbreaks in patients with herpes simplex virus (HSV-1) history, even if you haven't had a cold sore in years. Lip filler is a common trigger. If you have any history of oral or facial cold sores, disclose this before treatment—your provider should prescribe prophylactic antiviral medication (typically valacyclovir) to take before and after lip or perioral filler injections.
Immunosuppressants. Patients on medications that suppress immune function—for autoimmune conditions, organ transplants, or certain inflammatory conditions—have different healing profiles and higher infection risk. This affects timing, aftercare, and whether filler is appropriate at all.
Retinoids. Prescription tretinoin and high-strength retinol products thin the skin and increase sensitivity. Some providers ask patients to discontinue retinoids for several days before treatment to reduce irritation risk at injection sites.
Medical History Disclosures That Matter
Beyond current medications, certain medical conditions affect whether and how you can safely receive filler.
Autoimmune conditions. Lupus, rheumatoid arthritis, Sjögren's syndrome, and similar conditions can affect how your body responds to filler. Some autoimmune conditions are associated with higher risk of granulomas—inflammatory nodules that form around filler material and require treatment to resolve. This isn't always a contraindication, but it changes the risk conversation.
Bleeding disorders. Hemophilia and other clotting disorders significantly increase complication risk. Disclose any diagnosed bleeding disorder before treatment.
History of severe allergic reactions. If you've had anaphylaxis or severe allergic reactions to any injectable product, medication, or lidocaine (commonly included in filler formulations), this must be disclosed. Many fillers contain lidocaine for patient comfort—and that makes lidocaine allergy clinically significant.
Previous filler treatments and complications. Tell your provider what products you've had injected previously, where, and when. Layering different filler products in the same area or injecting over filler placed at another practice can cause unpredictable results. If you experienced any adverse reactions to previous filler—swelling that seemed disproportionate, firmness that didn't resolve, inflammation—describe it in detail.
Active skin infections or acne breakouts. Filler should not be injected through actively infected skin. Even a pimple at an intended injection site can carry bacteria into deeper tissue. Active facial cellulitis, shingles outbreaks on the face, or infected skin conditions are contraindications until resolved.
Recent dental procedures. This one surprises most patients: dental work—teeth cleaning, fillings, extractions, root canals—introduces bacteria into the bloodstream transiently. Biofilm around filler material can become a nidus for infection if bacteria are circulating post-procedure. Most providers recommend waiting at least two weeks after dental procedures before lip or perioral filler.
Lifestyle Factors That Affect Your Results
Smoking. Nicotine impairs circulation and collagen synthesis, affecting healing quality and longevity of results. You don't need to disclose your smoking status to receive treatment, but your provider may adjust expectations about how long results will last and how your skin will recover.
Alcohol. Drinking the night before or day of treatment increases bleeding risk and affects hydration. Most providers advise avoiding alcohol 24-48 hours before appointments.
Upcoming events. This seems obvious, but many first-time patients don't understand that bruising is normal and can last 1-2 weeks. If you have an important event—wedding, reunion, professional presentation—within two weeks of your appointment, your provider needs to know. They may adjust the timing of treatment or be more conservative with injection technique to minimize bruising risk.
Intense exercise plans. Vigorous exercise in the 24-48 hours following filler increases heart rate, elevates blood pressure, and can accelerate filler migration or worsen bruising. If you're a daily gym-goer, this affects your post-treatment instructions.
Red Flags During the Consultation
The pre-appointment conversation should flow both ways. While you're disclosing your history, you should also be evaluating whether the provider is asking the right questions. A competent injector conducts a thorough intake before any needle touches your face.
They should ask your full medication list. Providers who go straight to discussing your aesthetic goals without asking about medications are skipping a safety step.
They should ask about previous treatments. "Have you had filler before, and what product was used?" is a required question. If they don't ask, they're potentially injecting over unknown material.
They should examine your facial anatomy. Good injectors spend time looking at your face before discussing treatment plans—studying facial symmetry, skin quality, and how volume has changed with aging. Providers who immediately agree with whatever you describe wanting without physical assessment aren't doing a real consultation.
They should explain risks specific to you. Blanket statements like "bruising is possible" aren't adequate. Competent providers discuss which injection sites carry higher complication risk, how your specific anatomy affects technique, and what to watch for afterward.
They should not guarantee specific outcomes. Filler results depend on facial anatomy, product selection, technique, and how your individual tissue responds. Any provider guaranteeing specific millimeter changes or transformation timelines is overpromising.
They should discuss the dissolution option. Hyaluronic acid fillers (the most common type) are dissolvable with hyaluronidase. If your provider doesn't mention this when discussing lip filler, cheek filler, or under-eye filler, they're withholding information that significantly affects your informed consent.
What to Ask Your Injector
Beyond what you disclose, come prepared with questions that help you evaluate provider competence and safety standards:
What product are you using and why? Different HA fillers (Juvederm, Restylane, Belotero) have different properties—thickness, spreadability, hydrophilicity. Your provider should explain why a specific product is right for your concern and anatomy.
How much product do you plan to use? Overfilling is a real phenomenon and a significant problem in aesthetic medicine. A good provider gives you their recommendation in syringes with clinical reasoning, not pressure to buy more.
What is your reversal protocol if I don't like the results? Understand before injection whether the practice carries hyaluronidase and whether they would dissolve product that doesn't meet your expectations.
What are the signs of vascular occlusion and what do you do if it happens? This is the serious complication question. Vascular occlusion—filler blocking a blood vessel—is rare but can cause tissue necrosis or blindness in the worst cases. Providers who know exactly how to recognize and respond to this complication will answer clearly and confidently. Those who fumble the answer are telling you something about their emergency preparedness.
Arriving Prepared
On the day of your appointment:
Arrive with a clean face. Makeup, sunscreen, and products at injection sites complicate prep and can introduce contaminants. Come in clean.
Bring your medication list. A photograph of your current prescriptions is sufficient if you haven't memorized doses.
Eat beforehand. Fasting makes some patients light-headed or prone to vasovagal responses. Having a small meal before your appointment reduces this risk.
Don't arrive rushed. Feeling pressured for time increases anxiety and can prompt decisions you'll second-guess. Plan to spend 60-90 minutes for a first-time filler consultation and treatment.
The information you share before treatment is what allows your injector to do their job safely. Providers who ask thorough questions and take your disclosures seriously are demonstrating the standard of care you deserve. Providers who rush through intake or don't ask about your medications are signaling how they approach the rest of the treatment.
Your first filler appointment should feel like a medical consultation—because that's exactly what it is.
