If Terazosin is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your physician before combining Terazosin with the following:
Nonsteroidal anti-inflammatory painkillers such as Motrin and Naprosyn
Other blood pressure medications, such as Dyazide, Vasotec, Calan, and Verelan
Special information if you are pregnant or breastfeeding
The effects of Terazosin during pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, notify your physician immediately. Terazosin is not recommended during pregnancy unless the benefit outweighs the potential risk to the unborn baby. It is not known whether Terazosin appears in breast milk. Because many drugs do appear in breast milk, your physician may advise you to stop breastfeeding until your treatment with this drug is finished.
