I am 31 weeks pregnant can i take nighttime hylands cold and cough to help my cold symptoms so i can sleep?

Cold, Pregnant, Hyla: Yes, is safe. Generally speaking, in the early stages of pregnancy (the so-called "organ forming Period"), many obstetricians will carefully assess the risks of drug use, avoid the use of D, X-class levels of drugs and choose safer drugs to use; while pregnant middle and late, cold symptoms often more discomfort, such as fever causes tachycardia, headache, etc.; or because of nasal congestion causes shortness of breath, mild asthma, or severe cough causes uterine contractions or abdominal pain, and even unable to sleep, etc., so physicians as the case may give some analgesic antipyretics, antihistamines, or cough and phlegm drugs, relieve suffering, let Bulletin boards can get plenty of rest.

I would say NO: Herbs in Pregnancy is a huge topic. Hylands has about six herbs in it including Goldenseal which is generally considered to be contraindicated in pregnancy as it may cause premature contractions. Could use Robitussin, (guaifenesin) Hall's cough drops or cepacol lozenges, Vick's plain cough syrup or chicken soup. hope you feel better soon.
