 Frequent nosebleeds can be prevented in part by keeping the nostrils moist , and by applying saline solution , estrogen @-@ containing creams or tranexamic acid ; these have few side effects and may have a small degree of benefit . A number of additional modalities has been used to prevent recurrent bleeding if simple measures are unsuccessful . Medical therapies include oral tranexamic acid and estrogen ; the evidence for these is relatively limited , and estrogen is poorly tolerated by men and possibly carries risks of cancer and heart disease in women past the menopause . Nasal coagulation and cauterization may reduce the bleeding from telangiectasias , and is recommended before surgery is considered ; often , several sessions are needed . It may be possible to embolize vascular lesions through interventional radiology ; this requires passing a catheter through a large artery and locating the maxillary artery under X @-@ ray guidance , followed by the injection into the vessel of particles that occlude the blood vessels . The benefit from the procedure tends to be short @-@ lived , and it may be most appropriate in episodes of severe bleeding .
