A primigravid client visits the clinic for a routine examination at 35 weeks’ gestation. The client’s blood pressure is near the baseline of 120/74 mmHg with no proteinuria or evidence of facial edema.
The client asks the nurse, “What should I take if I get an occasional headache after looking at my computer at work all day?” The nurse instructs the client that she can occasionally take which of the following?
1. Acetaminophen (Tylenol).
3. Ibuprofen (Advil).
4. Naproxen (Aleve).
The nurse should instruct the client that symptoms from an occasional headache due to eye strain or continuous work at a computer can be relieved by acetaminophen. Although this drug causes prostaglandin inhibition, this effect is rapidly reversed and cleared with no apparent harmful effects in pregnancy.
If the headaches become more frequent or severe, the client should be instructed to contact her health care provider immediately. Aspirin should be avoided during pregnancy because it inhibits prostaglandin synthesis. It also decreases uterine contractility and may delay the onset of labor or prolong pregnancy and labor.
Aspirin decreases platelet aggregation, possibly increasing the risk of bleeding. Ibuprofen and naproxen can lead to premature closure of the fetal ductus arteriosus and decreased amniotic fluid with prolonged use. They may alsoprolong pregnancy or labor because of their antiprostaglandin effects.
