Anyone take Trental/Pentoxyfylline??

[sunfish]

Neurosurgeon prescribed 400 mg. of trental (generic name pentoxyfylline) three times per day.  Looking on the internet shows this drug has been used quite successfully in combatting radiation-induced side effects in cancer patients.  Especially for treating radiation-induced fibrosis after therapy for breast cancer.

I have lots of disequilibrium/balance problems, some increased hearing loss, and high blood pressure since CK.  The doctor says he hopes trental may help with any/all of these.

Anyone else take this stuff before?  Internet makes it sound like a safe, reasonable course of action.
