Hi Good271127, I am Sarah, a medical assistant at Anil Shah Facial Plastic Surgery. While there are no specific contraindications against drinking coffee while receiving PRP injections, it is generally recommended to avoid caffeine consumption for a few hours before and after the procedure. This precaution is to help reduce the risk of potential side effects related to caffeine, such as increased heart rate or blood pressure. During a PRP injection procedure, a patient's blood is drawn and processed to concentrate the platelet-rich plasma, which is then injected back into the body, typically the scalp for hair growth treatment. The process of drawing blood and undergoing injections can be mildly stressful for some individuals. Caffeine can further increase stress responses in some people, leading to potential discomfort during or after the procedure. To ensure a smooth and comfortable experience during PRP injections, it's advisable to avoid caffeine-containing beverages such as coffee, tea, energy drinks, and soda for at least a few hours before and after the procedure. Instead, opt for water or other non-caffeinated beverages. As always, it's best to follow the specific instructions provided by your healthcare provider or the medical professional performing the PRP injections. If you have any concerns or questions about your specific case, don't hesitate to discuss them with your healthcare provider before the procedure. They can provide personalized guidance based on your health status and medical history
