LANSING, Mich. — Manufacturing delays at several pharmaceutical companies are causing nationwide shortages of two critical chemotherapy medications – forcing Michigan hospitals and health systems to find alternative treatments for patients, some of which may be less effective. The two drugs are cisplatin and carboplatin and are used to treat several types of cancer, including bladder, lung, ovarian, and testicular cancers.
