Orthostasis warning: tamsulosin may cause dizziness or a decrease in blood pressure when you wake up after sitting or lying down.

After taking your first dose or a larger dose, be sure you know how tamsulosin affects you before doing any activity that may cause you harm.

Priapism warning: Rarely, tamsulosin may cause priapism. This is a persistent and painful erection that is not related to sexual activity.

If you have priapism, contact your doctor immediately. If priapism is not treated, it could cause permanent impotence (not being able to have an erection).

Skin reactions warning: Although it is rare, this medication can cause serious skin reactions, including a serious condition called Stevens-Johnson syndrome .

These skin reactions can cause elevated welts, facial swelling, fever and shortness of breath. See a doctor immediately or call 911 if you have signs of a sudden or severe skin reaction after taking this medication.

Warning intraoperative flaccid iris syndrome (IFIS): IFIS is a complication that can occur during surgery for cataracts or glaucoma .

Although it is rare, this problem has been reported with people taking tamsulosin. If you need to undergo cataract or glaucoma surgery, be sure to tell your doctor or surgeon that you are taking tamsulosin.
