Dilaudid, Ambien, Adderall: Lindsay Lohan's Dangerous Medicine Cabinet?

(CBS) Lindsay Lohan is having a bad week.

Tuesday, the scandal-ridden actress was sentenced to 90 days jail time for violating her parole. Today, the tabloids are claiming her medicine cabinet is filled with prescriptions for Dilaudid, Ambien, and Adderall. 

CBS News doesn't know if those claims are true, but according to experts, the drugs are powerful and potentially dangerous if taken together.

If you're taking Dilaudid and Ambien "both at the same time it had better be under the close supervision of a doctor because otherwise you're asking for trouble," says CBS News medical correspondent Dr. Jon Lapook.  "The combination of the two can depress your breathing and cause the oxygen in your blood to become dangerously low.  The combination of these two types of drugs is what I give to patients intravenously during a colonoscopy!"  

We're pretty sure Lilo is getting one of those, but TMZ suggested her dentist prescribed the Dilaudid.

Dilaudid is a powerful opiate similar to morphine which is used to treat moderate to intense pain. The drug is very addictive and in high doses can be fatal, according to WebMD. It is never recommended to mix it with alcohol.

Lohan has been banned from drinking alcohol by court order and was wearing an alcohol monitoring bracelet as part of her probation.

Ambien is typically prescribed for sleep disorders. Some report sleep walking or even sleep driving on it. In rare cases, it can be addictive, according to WebMD, which says withdrawal symptoms include nausea, vomiting and shakiness.

Adderall is a popular stimulant used to treat attention deficit hyperactivity disorder. It's also popular with students trying to stay up all night to study and is often abused as a party drug. Potential side effects, according to WebMD, include agitation, aggression and terrible mood swings.  Like Dilaudid, Adderall can be highly addictive, says the site.

Lohan was sentenced to 90 days in jail and 90 days in a drug rehabilitation center.  The ruling judge felt she violated her parole stemming from a 2007 drunk driving case by not attending alcohol education classes.
