Frequent insomnia may be caused by medication
Introduction: Sleepiness arrives, but you just can't fall asleep no matter how much you toss and turn in bed, which is truly agonizing. Yet, every day, more than just one or two people find themselves trapped in the predicament of insomnia. In fact, besides some common causes of insomnia, it is very likely that medication is the culprit. After adjusting the dosage or switching medications, the insomnia can be cured without special treatment.
Common medications that can cause insomnia include:
Antihypertensive drugs
Patients taking antihypertensive drugs who frequently experience insomnia might consider looking for the cause in their medication. If the antihypertensive drug is not chosen appropriately or the dosage is improper, it can lead to low blood pressure at night, causing insomnia. Patients should proactively inform their doctors about their insomnia problem, so the doctor can decide whether to adjust the drug dosage or switch to a different medication.
Glucocorticoids
Long-term, high-dose use of glucocorticoids can increase the body's excitability, leading to insomnia.
Diuretics
Their use can increase the frequency of urination. If taken before bedtime, it often affects sleep due to increased urination. Therefore, diuretics are best taken during the day. Additionally, diuretics can cause electrolyte imbalances; for example, potassium-excreting diuretics (like hydrochlorothiazide) can cause a potassium deficiency in the body, which can induce cardiac arrhythmias and also lead to insomnia.
Asthma medications
Drugs like ephedrine and theophylline, due to their central nervous system stimulant effects, can excite the cerebral cortex and subcortical centers. Some patients may become agitated and experience insomnia after taking them. An excessive dosage can also lead to delirium and convulsions. When these medications are taken in the evening, it is advisable to also take a sedative-hypnotic drug to prevent insomnia.
Antidepressants
Commonly used antidepressants such as imipramine, clomipramine, fluoxetine, and paroxetine can all cause insomnia.
Antibiotics
Most antibiotics can irritate the gastrointestinal tract, and taking them can easily lead to gastrointestinal reactions like acid reflux, nausea, and vomiting, so it's best not to take them on an empty stomach. If taken before dinner or before bedtime at night, they can affect sleep due to nausea and upper abdominal discomfort. Furthermore, quinolone antibiotics have a strong central nervous system effect, and can cause headaches, dizziness, and poor sleep after ingestion, so they should be avoided before bedtime.
