Before PRP injections, it’s important to avoid taking blood-thinning medications, such as aspirin or ibuprofen, for at least a week to reduce the risk of bruising. Alcohol should also be avoided 24-48 hours prior to treatment. After the procedure, it’s essential to avoid touching or massaging the treated area for 24-48 hours, and refrain from strenuous activities, excessive heat, and sun exposure for a few days to minimize swelling and irritation. Keeping the area clean and following the practitioner’s aftercare instructions will help ensure optimal results.
