Despite the fact that they are frequently turned to for relief, prescription drugs cause over 100,000 deaths per year and place nearly 1.5 million people in the hospital due to severe side effects (1).

Top 3 Types of Meds That Cause Memory Loss

Some side effects of these drugs are so severe that they have been found to affect the brain and cause memory loss. Here we cover the three categories known to cause memory loss and cognitive problems.


1. The “Anti” Drugs

Drugs such as antihistamines, antidepressants, antipsychotics, antibiotics, antispasmodics, or antihypertensives, inhibit the activity of the neurotransmitter acetylcholine, which plays a critical role in memory and cognitive function.

Unfortunately, many of these drugs are available over the counter, therefore causing even further damage to those who have not had proper doses measured out for them (2) .

2. Sleeping Pills

A common side effect of sleeping pills is both short and long term memory loss. In fact it has been found that all sleeping pills produce some level of impaired memory and performance. Sleeping pills suppress the action potentials of a wide variety of brain cells and reduce our alertness, vigilance, and judgement (3).


Sleeping pills have been known to create a state similar to “blacking out”, which occurs when a person has too much alcohol in their system and are unable to recall previous events due to damaged brain cells (4)

3. Statin Drugs

The FDA has recently began to advise consumers and professionals to monitor their use of these cholesterol-lowering medications due to reports of cognitive impairment and memory loss.

It’s been reported that the drug can cause patients to feel “fuzzy” or unfocused in their thinking, along with a sudden frequency of feeling forgetful (5).
