Tenecteplase falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Your doctor and you will decide if the benefits outweigh the risk of using tenecteplase.
