will Nyquil affect liver test? Doc told me was one elevation on routine yearly blood test, so asked me to take another test in 30 days, no etoh 10 days before test, order reads ALT live test. Have had bad cough, been taking one dose Nyquil last about 4 nights, and today took one dose Dayquil. Wife pointed out that they have etoh in them. Question is, does that count as alcohol ingestion, so should I wait another ten days after I m done taking Nyquil (not going to stop until cold gone, it s a life saver at night!). Other useful data may be: Prior to blood test had been light etoh consumption say about 7 beer a week, but prior to that over the summer, too much beer, probably about 14 beer a week (beer I drink is rarely above 6%, usually below 5%. I exercise enough, but about 25 lb overweight, I ll lose weight I promise. And I have very good diet, though eat too much. I don t smoke. No drugs. Only med is Concerta, 36 mg, one 30 tab bottle lasts about 4 months. Thank so much in advance. And have a good day, take good care of yourselves, I wish you medical professionals didn t have to work so hard and didn t have to do so much paperwork. Thanks so much in advance!
