My doctor recently prescribed me Truvada as a PrEP, which I just started today. Throughout the day I have experienced various side effect symptoms, such as a slight headache, weakness, fatigue. However, overall, the most persistent symptom I have been experiencing is an itching/tingling/slight burning in my face and lips, even somewhat of my scalp. Is it normal to experience side effects when starting treatment, as if my body is adjusting to the medication, or is this a signal that I may not be compatible with Truvada.
