Build one accurate list
Record prescription medicines, over-the-counter products, supplements, topical creams, acne treatments and recent courses such as antibiotics. Include dose or frequency where known, why you use them and the prescribing clinician. List allergies and describe the reaction rather than writing only ‘sensitive’. Add previous problems with adhesives, antiseptics, latex, anaesthetics, skincare, hair dye, tattoo pigment or procedures. A current photograph of labels can prevent spelling errors, but do not share credentials or unrelated private records.
Explain why the information can change a plan
Some medicines or products may increase light sensitivity, bruising, irritation or healing concerns; allergies may influence cleansers, dressings or topical products. The American Academy of Dermatology advises telling the treating dermatologist about medicines, supplements and skincare before laser treatment. FDA guidance for non-invasive contouring also highlights personal factors such as active or metal implants for some technologies. Disclosure allows the provider to modify, seek medical advice or postpone rather than discovering a conflict during treatment.
Do not create risk by stopping treatment yourself
A cosmetic appointment is not a reason to skip or discontinue prescribed medicine without the clinician who manages it. Sudden interruption can be harmful, and the person providing the aesthetic service may not be the prescriber. If a potential interaction is identified, ask for a clear, documented pathway: which clinician should advise, what information they need, and whether postponement is the safer option. Do not accept vague instructions to ‘stop blood thinners’ or ‘pause all actives’ without procedure-specific and medically appropriate direction.
Update the list and keep a reaction record
Repeat disclosure when medicines, supplements, pregnancy status, implants, allergies or skin condition change, even if you previously attended the same provider. Before consent, confirm the exact procedure, products, treatment area and aftercare. If a reaction occurs, record timing, symptoms, photographs and everything applied, and contact the provider or appropriate healthcare professional. Seek urgent help for breathing difficulty, facial or throat swelling, faintness or other signs of a severe allergic reaction. A complete record improves assessment; it cannot guarantee zero risk.
Common questions
Should I stop medication before treatment?
Not on your own. Tell the provider what you take. If there is a concern, the relevant prescriber or healthcare professional should advise whether modification is appropriate; otherwise postpone the elective procedure.
What counts as an allergy worth mentioning?
Report diagnosed allergies and previous rashes, swelling, breathing symptoms or other reactions to medicines, latex, adhesives, antiseptics, anaesthetics, cosmetics, dyes, pigments or procedure products. Describe what happened and when.
