Heidi Fleiss is shrugging off her arrest in Nevada on charges of illegal possession of prescription drugs. The former Hollywood madam admits she didn’t have prescriptions for Vicadin and Xanax when cops pulled over Thursday. “But I will produce them,” she tells us. As for John Owen, the passenger busted for marijuana possesion, she says, “He’s my plumber. He didn’t even have enough pot to roll a joint.” Despite her arrest, Fleiss likes living in the desert town of Pahrump, where she’s installed her 20 parrots on her 10-acre spread. She still hopes to open a legal brothel but, for now, is satisfied with her fancy laundermat, Dirty Laundry. “There’s a sweet older religious woman working there,” she says. “I told her to give the customers whatever they want — that includes [oral sex] in the bathroom. She’s getting used to my sense of humor.”

Gwyneth Paltrow is still staying mum about what put her in the hospital last month, but she assures us, “I feel great. People made a big deal out of nothing.” The Oscar winner certainly looked in the pink last week at the benefit for Madonna’s Raising Malawi charity. Paltrow said that, like Madonna, she and hubby Chris Martin are open to adopting a baby, but “we might get one from Brooklyn. No baby is more helpless than another baby. And I’m a New York girl.” Paltrow supported her pal’s cause by paying $75,000 for a trip to the Maldives. The evening was underwritten by Gucci, which just opened its fab Fifth Ave. store.

“I was high from age 11 to 35,” singer and reformed pothead Lenny Kravitz says in the new issue of Blender mag. The crooner starting smoking weed because “I didn’t touch alcohol. I drank Manischewitz wine at a Chanukah party when I was 7 and threw up all over the house. I was in bed for a week.”

Rudy Giuliani has been serving John McCain well on the campaign trail — increasing speculation that America’s Mayor could be rewarded with a major post in a McCain administration. But according to a well-placed source, McCain’s staff was cool to Giuliani when he raised the possibility of a cabinet post a few days before Giuliani dropped out of the race. “He mentioned four posts,” claims the source. “McCain’s people said, ‘No, no, no, and no.’” Two senior McCain advisers said they had no knowledge of such a meeting. A Giuliani insider concurs: “The mayor would never meet with staff and engage in that kind of conversation. He’s supporting McCain because he believes he’s the right guy for the job.”

Sharon Bush doesn’t need tips on how to deal with her former in-laws, but Lauren Bush’s mom showed up at Touch for the party for lawyer and best-selling author Mark W. Smith’s latest book, “The Official Handbook of the Vast Right-Wing Conspiracy.”

Hmm … what large-egoed playwright could Paul Rudnick be talking about in the new book “Writing: Working in the Theatre,” a compilation of the best moments from the American Theatre Wing’s famous forums? “I met [a] playwright who was not really a very good playwright, but one of the most confident human beings I’ve ever met. She was so sure of her own genius that at the end of each day of writing, she would put the pages she’d worked on in the freezer, so in case her apartment caught on fire, they would be saved — or at least chilled.”

XANAX should not be used if you have a condition called acute narrow angle glaucoma. It can be used if you have open angle glaucoma. Ask your doctor if you have questions.

Side effects, if they occur, are generally observed at the beginning of therapy and usually disappear upon continued use. The most commonly reported side effects in clinical trials were drowsiness, fatigue, impaired coordination, irritability, light-headedness, memory impairment, insomnia, and headache.

To assure safe and effective use of benzodiazepines make sure that you:

Inform your physician about any alcohol consumption and medicine you are currently taking, including medication you may buy without a prescription.
XANAX is not recommended for use in pregnancy. Inform your physician if you are pregnant, if you are planning to become pregnant, or if you become pregnant while taking this medication.
Inform your physician if you are nursing.
Until you experience how the medication affects you, do not drive a car or operate hazardous machinery.
Do not increase the dose even if you think the medication isn’t working, without consulting your physician.
Benzodiazepines, even when used as recommended, may produce emotional and/physical dependence.
Do not stop taking this medication abruptly or decrease the dose without consulting your physician, since discontinuation symptoms may occur.
Important Considerations for Patients Diagnosed with Panic Disorder
At doses greater than 4 mg per day, XANAX has the potential to cause severe emotional and physical dependence in some patients and these individuals may find it exceedingly difficult to terminate treatment. It is important that your physician help you discontinue this medication in a careful and safe manner to avoid overly extended use of XANAX. In addition, the extended use of XANAX at doses greater than 4 mg per day appears to increase the incidence and severity of withdrawal reactions when the drug is discontinued. These are generally minor but seizure can occur, especially if you reduce the dose too rapidly or discontinue the medication abruptly. Seizure can be life-threatening.
