question: Hello, My husband (age 44) just began taking Levemir Flexpen last night. This morning, about 9 hours after administering the medicine, he woke up with a nosebleed. This is an unusual occurrence for him. The pharmacist said this is not an expected side effect and suggested we call the doctor when the office opens. We are waiting for that to happen. Is this a side effect you are familiar with? His bp is 141/91. He is on bp medication and this is a slightly high read for him. His blood sugar is 226 which is a typical read for him. No other symptoms except slightly shaky feeling but he is nervous.
