4 Precautions To Take

Go to all your doctor and lab appointments, so that your condition is regularly monitored and side effects can be avoided or treated. Watch out for signs and symptoms of a severe allergic reaction or to this medication.

Intravenous Factor XIII can cause anaphylaxis, which is a serious and life-threatening condition.

Since Intravenous Factor XIII is a clotting agent, you are prone to developing blood clots. Again, if you have a history of blood clots, inform your doctor.

Also, get in touch with your physician immediately if you or someone in your family has sudden or severe headache, vision or speech problems, shortness of breath, chest pain, or weakness or numbness while you are receiving this medicine.
