I’ve googled around about this, but can’t find a satisfactory answer, so I come here.
I need to go in in the next few days for a routine fasting blood test, but I’ve been getting nighttime headaches - mild migraines, actually. I take ibuprofen or Imitrex for these, and can’t find out if I ought not to take them during the night of my fast.
Actually, it’s more the kind of test to find out if my liver’s tolerating the statin drug now. We already know that my cholesterol’s down.
Ibuprofen or Sumatriptan (Imitrex) shouldn’t causes any changes in a cholesterol test. However, I don’t know if Sumatriptan can causes a change in a Liver Function test or not, so if you are actually getting a LFT then I wouldn’t take the Sumatriptan just in case.
Ibuprofen is not metabolized or excreted by the liver, so it would be safe to take if needed.
Welp, I had planned on doing the blood draw this morning. I woke up at 3:30 a.m. just starting to hatch a migraine, and said “Screw it. I can’t not take any Imitrex”, and took it. I went to the lab as scheduled, and told the phlebotomist what I had taken, and she said it wouldn’t be a problem. So you have it from the horse’s mouth, as far as Imitrex goes, anyway.
Oops, I had better belatedly take my omeprazole now.
