Whether pregnant women can take Compound Ferrous Sulfate and Folic Acid Tablets should be determined by considering the drug's effects and the characteristics of pregnancy.

Compound Ferrous Sulfate and Folic Acid Tablets are a combined formulation used for iron supplementation and folic acid replenishment. Ferrous sulfate helps correct iron deficiency anemia, while folic acid prevents fetal neural tube defects. These tablets are commonly used for treating iron deficiency anemia. During pregnancy, the demand for both iron and folic acid increases. If diagnosed with iron deficiency anemia, it is generally safe for pregnant women to take this medication appropriately under a doctor's guidance.

However, it is important to follow the principle of medical necessity when using medications during pregnancy. In the early stages of pregnancy (a critical period for fetal development), self-administration of the drug is not recommended unless there is a clear medical indication. Additionally, the iron in the medication may irritate the gastrointestinal tract, causing side effects such as nausea, vomiting, and constipation. Pregnant women, being more sensitive to medications, should monitor their reactions after taking the drug. If severe gastrointestinal reactions or allergic symptoms occur, the medication should be discontinued immediately and medical advice sought.

Before taking the medication, a clear diagnosis must be made through blood tests such as a complete blood count. The dosage must strictly be controlled under a doctor's supervision to avoid iron toxicity caused by excessive iron supplementation or the risk of excess folic acid intake masking symptoms of vitamin B12 deficiency.
