Burroughs Wellcome Co. Friday announced it is returning Sudafed 12-hour cold medication to the market in tablet form after cyanide-laced capsules killed two people in Washington state.

Burroughs Wellcome recalled Sudafed 12-hour capsules in March following the reports of three poisonings - two of them fatal - from tainted Suafed capsules. To date, there have been no arrests in the cases.Burroughs Wellcome plans to ship the first boxes of the solid coated-tablet form of Sudafed 12-hour Monday, and the pills should be available to consumers within two weeks.

The tablets, which like the capsules will be packaged in a foil-backed "blister pack," will be in the same price range as the capsules, company spokeswoman Sharon Haggerty said.

"We have to keep in mind that no product form is completely tamper-proof. However, history has shown that this (tablets) is not a form that has been tampered with," she said.

Sudafed products generated $109 million in sales in fiscal 1989, and the 12-hour capsules produced 15 percent of that total, Haggerty said.
