Alcohol before PRP: preparation questions
If you drank alcohol before a PRP appointment, tell your treating clinician what you drank, how much and when, and ask whether the appointment should go ahead. Alcohol can affect platelet function, but the alcohol review does not establish a waiting period before PRP.[1]

Before treatment
Ask for preparation instructions before the appointment. If you have already had a drink, contact the treating team with the amount and timing rather than choosing a waiting period yourself. Include any medicines or supplements you take in that conversation.
A review of alcohol and blood clotting describes effects on both platelet activation and inhibition. It examines clotting mechanisms, not whether a particular amount of alcohol changes cosmetic PRP results.[1]
- What preparation instructions apply to my treatment area and appointment?
- Does the amount and timing of my alcohol intake change the plan?
- Which medicines and supplements do you need to review?

After treatment
Follow the aftercare plan from the treating clinician. The clinic’s PRP service page lists avoiding alcohol during the first week after treatment (checked 18 October 2026). That is an aftercare instruction; it does not set a one-week rule before PRP.

Medicines: ask your treating clinician
Bring the generic names, doses and reasons for taking your medicines, including occasional painkillers. Some anti-inflammatory painkillers affect platelet clumping; the effect varies by medicine and dose.[2] Ask the clinician whether any change is needed and who should make that decision.
In a laboratory study of 12 healthy men, low-dose aspirin reduced the release of several growth factors when PRP was activated through one pathway. The study did not establish how aspirin changes skin or hair treatment results.[3]

Do not stop prescribed aspirin or a blood thinner on your own for PRP. A review of medicines in skin surgery describes clotting risks when antithrombotic treatment is stopped.[4] Any change needs a decision from the prescribing clinician and treating team.
| What you take | What to discuss |
|---|---|
| Prescribed aspirin or blood thinners | The name, dose, reason for treatment and prescribing clinician. |
| Occasional painkillers | The active ingredient, dose and when you last took it. |
| Vitamins and herbal supplements | A complete list, including products taken only occasionally. |
Bring the packets or photos of their labels if you are unsure of the generic names. Ask the clinician or pharmacist to identify the ingredients and discuss pain relief for your own treatment plan.
What should I tell my clinician if I drank alcohol before my appointment?
Tell them what you drank, roughly how much and when, along with your medicines and supplements. Ask whether to keep or reschedule the appointment and which preparation instructions to follow.
Does a week without alcohol after PRP mean a week before it too?
No. An aftercare interval does not establish a preparation interval. Ask the treating clinician for the instructions that apply before your appointment.
Should I stop aspirin or change painkillers before PRP?
Do not change prescribed aspirin or blood thinners on your own. Give the treating team your medicine list and ask the prescribing clinician about any proposed change.[4]
