What are side effects of alpha blockers?

The side effects for alpha blockers (very potent medications often used for people whose blood pressure doesn't respond to less strong drugs) are mostly about headaches, and about weight gain and heart failure.

Some men on alpha blockers experience dizziness, lack of energy, swelling of the ankles, or retrograde ejaculation, which occurs when semen flows back into the bladder rather than out through the penis upon orgasm. You may need to make several visits to your doctor and try several prescriptions to arrive at the appropriate medication and the right dose.

Side effects may include headaches, drowsiness, weakness, fainting, nasal congestion, and nausea. Other side effects may include frequent urination or loss of bladder control, and a rapid, strong, or irregular heartbeat. Alpha blockers can make it dangerous to drive or to operate machinery.
