Real Housewives of Beverly Hills' Kim Richards in Rehab

Sister of Kyle Richards and aunt to Paris Hilton talked about various prescription meds she was taking on Nov. 7 episode

Kim Richards appears interested in dialing down the drama.

The Real Housewives of Beverly Hills star has checked into an undisclosed treatment facility to address her issues, multiple sources tell Entertainment Tonight.

While Bravo has yet to comment, Richards' behavior on the controversial hit show has been notable for its trainwreck-reminiscent qualities. The sister of Kyle Richards and aunt to Paris Hilton did present a plausible explanation on the Nov. 7 episode...

During a visit to a plastic surgeon, Kim tells the doctor that she's taking a prescription drug cocktail of the antiseizure medication Topomax, Trazodone and Lexapro to combat depression and anxiety—and the doc tells her that the effects of all three could be giving her an intoxicated vibe.

Topomax, while technically an antiseizure med, has multiple other uses as well, such as migraine prevention, and has been known to be prescribed to treat alcoholism.

After a sisterly blowup at castmate Taylor Armstrong's birthday party last season, Kyle yelled at Kim: "You are an alcoholic! Yeah, that's right. I've said it now and everybody knows."

And on tonight's Watch What Happens: Live!, host Andy Cohen asked Taylor about Richard's reported check-in to rehab.

"You know, I didn't know that, "Armstrong tells Cohen. "But I adore Kim and I stand behind her and if there's anything I can do to support her. But if she's getting healthy, you know, what more could we ask?"

Whatever Kim's problem is, first step is admitting that she has one, right?
