In its fourth day of business, the American Drug Club of Lansing is putting up larger signs while federal officials are trying to find ways to shut it down.

Staff at the prescription drug service center, 1456 E. Michigan Ave. provide price information and assist customers in ordering drugs from Canadian pharmacies to save at least 40-50 percent from U.S. prices.

The store is under scrutiny by U.S. Rep. Mike Rogers, R-Mich., who asked the Food and Drug Administration to investigate the businesses he says are a "prescription for disaster."

Rogers, whose Michigan office is across from the new store, said Thursday he's concerned with the absence of a pharmacist.

"Everyone who walks in the door is taking a risk," Rogers said. "There should be a link between the doctor and the mailman."

But the store has already seen 200 customers in its first days, some of them leaving the store in tears after seeing the savings, said Robert Zeineh, president of the Lansing store.

The company has stores in multiple states, including four in Michigan - none of which have been forced to shut down yet.

American Drug Club spokesman Mike Pirages says the complaints result from Republican ties to drug industries.

"It's all about money, it's not about safety," Pirages said. "We urge that the buyer beware just like Rogers does. "We're open to answering all questions."

The Lansing-based advocacy group Michigan Pharmacists Association also has interest in the company, sending a complaint Thursday to the state Consumer and Industry Bureau of Health Services.

Larry Wagenknecht, CEO of the Michigan Pharmacists Association, said he asked the bureau to either make the company obtain a pharmacy license or cease and desist.

The Michigan Public Health Code requires a license to distribute prescription drugs and federal law prohibits importing prescription drugs into the country, he said.

"The reality is they can't guarantee what you're going to get," Wagenknecht said. "There are a lot of little white pills out there."

Pirages said that since the American Drug Club employees only offer information on ordering the prescription drugs, they are not in violation. The association sent a letter to the state bureau Aug. 6 and there has been no order to shut down, Pirages said.
