High-quality research on the safety and effectiveness of over-the-counter medications in pregnancy is limited. Physicians should explore nonpharmacologic treatments before recommending medication. For nausea and vomiting in pregnancy, vitamin B6 (pyridoxine), H1 antihistamines, and ginger are safe and effective. ⋯ The safety of acetaminophen for the treatment of headaches and low back pain during pregnancy has come into question with recent studies; therefore, judicious use is advised. Physicians should screen all pregnant patients for their risk of developing preeclampsia and initiate low-dose aspirin from 12 weeks' gestation until delivery for those at increased risk. Data are limited on the safety and effectiveness of herbal supplements during pregnancy.

Hypertension is a leading modifiable risk factor for cardiovascular disease and the most common chronic condition seen by family physicians. Treatment of hypertension reduces morbidity and mortality due to coronary artery disease, myocardial infarction, heart failure, stroke, and chronic kidney disease. The use of ambulatory and home blood pressure monitoring improves diagnostic accuracy. ⋯ Evidence strongly supports reducing blood pressure to less than 140/90 mm Hg to reduce the risk of all-cause and cardiovascular mortality in adults with hypertension. Lowering blood pressure to less than 135/85 mm Hg may further reduce the risk of myocardial infarction. Clinical judgment and shared decision-making should guide treatment of patients with mild hypertension and older adults who may be more susceptible to adverse effects of antihypertensive medications and tight blood pressure control.
