MALLINCKRODT PROVIDES NEAR-TERM OUTLOOK
IN CONJUNCTION WITH THIRD QUARTER EARNINGS REPORT

ST. LOUIS, Mo., April 21, 1998 - During a conference call earlier
today to discuss third quarter results with analysts, Mallinckrodt
Inc. (NYSE:MKG) Chief Financial Officer Michael A. Rocca commented on
the near-term outlook for fiscal years 1998 and 1999.  While stating
that earnings for all of fiscal 1998, ending June 30, will be in line
with overall market expectations, he indicated that certain factors
will impact fiscal 1999 earnings growth.

     The three factors noted by Rocca that will have an influence on
fiscal 1999 are a decrease in ongoing earnings, resulting from the
divestiture of the company's specialty industrial chemical
businesses; continued price deterioration in the X-ray contrast
business, resulting in reduced imaging business results; and the
delay the company experienced in marketing OPTISON(*), due to later-
than-planned regulatory approval, which is pushing the cardiac
ultrasound contrast imaging agent's ramp-up and earnings contribution
out by about a half year. 

     While the company's revised long-range forecast and fiscal 1999
operating plan, currently being prepared under the normal planning
process, will not be complete for the next several months, it is
likely that FY99 earnings per share will be below $2.60, which is at
the lower end of the range mentioned by investment analysts in their
previous projections.

     Based in St. Louis, Missouri, and operating in more than 100
countries globally, Mallinckrodt had fiscal 1997 net sales of $1.9
billion.  The Mallinckrodt web site address is(www.mallinckrodt.com).

testing, and marketing of products; difficulties or delays in
receiving required governmental or regulatory approvals; market
acceptance issues, including the failure of products to generate
anticipated sales levels; difficulties in rationalizing acquired
businesses and in realizing related cost savings and other benefits;
the effects of and changes in trade, monetary and fiscal policies,
