Taking Phenergan While Pregnant
Phenergan® (promethazine hydrochloride) is a prescription medicine commonly used for treating nausea and vomiting. At this time, the full risks of taking Phenergan while pregnant are unknown. However, the medication is often used to treat severe morning sickness and can be used as a sedative during labor.
Based on limited information gathered from reports on pregnant women who used Phenergan, there is no strong evidence to suggest that the medication would cause any birth defects. Although the drug is approved to be used during labor, there is some evidence that it might increase the risk of breathing problems in newborns, although not all studies indicate that this is really a problem with Phenergan.
If you are pregnant or thinking of becoming pregnant, let your healthcare provider know. He or she will weigh the benefits and potential risks of using Phenergan during pregnancy before making a recommendation in your situation.
