A round blue pill with the imprint TEVA on the front, and 3927 on the back of it is 10mg of Diazepam (made by Teva Pharmaceuticals).
Diazepam is a benzodiazepine and anticonvulsant that is used to treat Alcohol Withdrawal, Night Terrors, Seizures, and Anxiety, among other illnesses. Abuse of this drug may lead to psychological or physical dependence.
This prescription-only medication is not classified as a risk during pregnancy, but should be used only under a doctor's supervision.
An article recently published in the journal Thorax warns that taking benzodiazepines may be associated with a 54% increase in the risk of pneumonia, and those that did contract the disease were found to be a fifth more likely to die within a month and a third more likely to die within three years.
