We all know the obvious drugs that can contribute to insomnia, so we're not going to harp on about alcohol, caffeine and nicotine again. Instead, we want to bring your attention to the following types of medication:
Medications for attention deficit disorder may cause insomnia
Children and adults who are on stimulant therapy for attention deficit disorder should be aware that if they take their medication too late in the day, or at too high a dose, it may make it more difficult to fall asleep.
Medications for depression may cause insomnia
Selective serotonin reuptake inhibitor (SSRIs) and selective norepinephrine reuptake inhibitor (SNRIs) can decrease REM sleep, cause an increase in restless leg syndrome and cause insomnia. Taking these pills earlier in the day may improve sleep, although sedatives such as mirtazapine and trazodone may be better alternatives.
Medications for hypertension or high blood pressure may cause insomnia
Anti-hypertensive drugs can not only cause insomnia, they can also cause nightmares and increase the number of times you awaken during the night to urinate.
A better alternative may be Angiotensin-converting-enzyme (ACE) inhibitors which appear to have no significant impact on sleep quality.
Never change your drug regimen without seeking your doctor's advice first.
