If you happen to’ve used Depo-Provera previously, Dr. D’Amico says you’re doubtless positive. “As soon as the drug is out of the system, the excessive dose of the hormone is gone and now not ‘feeds’ the tumor cells,” he says. “What issues in these sufferers is signs. If you happen to expertise persistent complications, imaginative and prescient adjustments, seizures, or new neurological issues, then it’s affordable to hunt medical analysis no matter contraceptive historical past.”
