Pregnancy
- 54%
of the 825 studies behind these common medicines did not allow pregnant women.
- 0
of those studies recorded whether anyone was pregnant.
- 2 of 10
common medicines have even one finished study focused on pregnancy with posted results.
Pregnant women take medicines like everyone else, often several at once, yet research treats them as invisible. Every report here makes them visible.

Pregnancy exposure registries follow women who take a medicine while pregnant. The FDA keeps the official list.
What is known for each common medicine
| Medicine | Studies that barred pregnant women | Pregnancy studies | What the FDA label says |
|---|---|---|---|
| pantoprazole | 68% | None found | Studies that followed women who took it while pregnant found no link to birth defects. Animal studies showed bone changes in babies, so the label still warns of possible harm. |
| methylphenidate | 54% | None found | Studies of pregnant women give mixed answers about birth defects and miscarriage. A national registry is collecting more data (1-866-961-2388). |
| simvastatin | 55% | None found | Stop taking it when you find out you are pregnant, or ask your doctor. Because of how it works it might harm the baby. It was never tested in pregnant women. |
| spironolactone | 49% | 1 found, 0 with results | In animal studies it changed how male babies developed. A few reports in pregnant women didn't show birth defects, but there is very little information. |
| losartan | 57% | 1 found, 1 with results | Can seriously harm or kill an unborn baby, especially in the 2nd and 3rd trimesters. Stop taking it as soon as you know you are pregnant, and talk to your doctor. |
| metoprolol | 46% | None found | Studies that followed pregnant women have not linked it to problems for the baby. Uncontrolled high blood pressure in pregnancy is risky in itself. |
| lisinopril | 47% | None found | Can seriously harm or kill an unborn baby, especially in the 2nd and 3rd trimesters. Stop taking it as soon as you know you are pregnant, and talk to your doctor. |
| amlodipine | 55% | 2 found, 2 with results | There is too little information to know if it causes birth defects or miscarriage. |
| atorvastatin | 57% | 3 found, 0 with results | Stop taking it when you find out you are pregnant, or ask your doctor. Because of how it works it might harm the baby. It was never tested in pregnant women. |
| zolpidem | 49% | None found | Taking it late in pregnancy can make newborns very sleepy and slow their breathing. It wasn't studied in pregnant women. |
Not conclusive. This sums up public study records — it can't tell you how a medicine will affect you, and missing data doesn't mean a medicine is unsafe. Talk to your doctor or pharmacist before changing anything.
