Lorazepam is a short half-life benzodiazepine. On average, the dose reaches its peak blood levels in about seven to eight hours. As I came to understand how quickly the concentration of the drug in my bloodstream was falling each day, my experience of the previous five years started to come into focus. Because I had been taking the medication only in the morning and in the evening, I had been going through interdose withdrawals on a daily basis, with all the same symptoms that would attend my eight-month taper.

That’s right: I had been having withdrawal symptoms every single day for four years. No one had ever warned me about how the medication worked, so I couldn’t figure out why I was on such a physical and emotional roller-coaster ride. Nothing in my life seemed to account for it, and the only response from my prescribing doctors was to increase my dosage.

These increases did not work. In addition to the impact of falling blood concentrations, daily withdrawal symptoms occur because of the tolerance that the body develops, very quickly, to the drug itself. As Dr. C. Heather Ashton writes in Benzodiazepines: How They Work and How to Withdraw, these drugs “lose much of their efficacy because of the development of tolerance. When tolerance develops, ‘withdrawal’ symptoms can appear even though the user continues to take the drug.” (Chapter II)

Because they quickly become ineffective and trigger daily withdrawal symptoms, benzodiazepines cause a host of problems, many of which they were intended to manage. In early 2009, after four years of benzodiazepine use, I exhibited difficulties common to benzodiazepine users. I was crying on a regular basis. I was falling into a depression unlike anything I had ever experienced. My anxiety was nearly paralyzing. And I had become almost housebound. The outside world felt overwhelming, and going out triggered both fear and exhaustion.

All of these symptoms amount to a textbook case of the impact of benzodiazepines. In her research, Dr. Ashton determined that people who use these drugs become ill with a number of psychiatric conditions. “Many patients,” she writes, “find that anxiety symptoms gradually increase over the years despite continuous benzodiazepine use, and panic attacks and agoraphobia may appear for the first time after years of chronic use.” She adds that long-term benzodiazepine use can cause depression in people with no history of it and can aggravate depression in people already suffering from it.
