Thank you for your reply. My BP was high and when feeling light headed it was 161/74. I was well hydrated before the injection and drank a lot of water. I noted that one of the side effects of Evenity is dizziness...mine was temporary and subsided after more than one-2 hours. Yes, I was very anxious before my first injection. I am not sure that the light headedness was related to my anxiety and think it was a reaction to the drug as it occurred 30 minutes after the injection. I am feeling fine today. No side effects so far and tolerating the drug well. I am wondering if this will occur again for the next injection and how to manage feeling high headed. I sat in one place to rest and drank water. Having a friend meet me was of great help as well.
