Allergy medication side effects: drowsiness, dry mouth, urinary retention, altered mental state
Allergy medications, such as antihistamines, can cause a range of side effects, including drowsiness, dry mouth, urinary retention, and altered mental state. While these medications can help alleviate allergy symptoms, it is important to be aware of their potential side effects and take them appropriately.
Drowsiness is a common side effect of allergy medications, particularly first-generation H1 antihistamines. These older antihistamines more easily cross the blood-brain barrier and interact with the central nervous system, causing drowsiness. While this side effect may be desirable for those seeking a good night's sleep, antihistamines are not recommended for this purpose due to a lack of research supporting their effectiveness and the potential for harmful long-term side effects. Additionally, daytime drowsiness can impact alertness and cognitive function, with studies showing increased fatigue, decreased motivation, and impaired driving performance.
Dry mouth is another potential side effect of allergy medications, including antihistamines and decongestants. While dry mouth may be caused by underlying medical conditions, the use of these medications can exacerbate the issue. Dry mouth can have a negative impact on oral health, and it is recommended to consult a dentist or doctor if this side effect occurs.
Urinary retention and incontinence are also possible side effects of allergy medications. Antihistamines, such as diphenhydramine (Benadryl) and chlorpheniramine (Chlor-Trimeton), can relax the bladder, impairing its ability to expel urine effectively. This can lead to a frequent urge to urinate as the bladder fills up quickly and sends signals to the brain. Additionally, decongestants can constrict the bladder's sphincter and prostate, making it difficult for urine to pass.
Allergy medications have also been associated with an altered mental state, particularly in older adults. Diphenhydramine, a common antihistamine, has been linked to dizziness, confusion, sedation, blurred vision, and impaired cognitive function. Multiple studies have shown that diphenhydramine can negatively impact alertness, attention, memory, executive function, reaction time, and vigilance. An observational study reported that diphenhydramine treatment in older hospitalized patients increased the risk of delirium symptoms, including inattention and disorganized speech. Anticholinergic medications, including some allergy drugs, have been associated with an increased risk of dementia and Alzheimer's disease.
In conclusion, while allergy medications can effectively manage allergy symptoms, it is crucial to be aware of their potential side effects. Drowsiness, dry mouth, urinary retention, and altered mental state are among the possible adverse effects of these medications. It is recommended to consult a healthcare professional before taking any allergy medication to ensure safe and appropriate use.

Natural sleep aids: melatonin, L-theanine, CBT, exercise, diet
While antihistamines and other over-the-counter sleep aids may help you fall asleep faster, they are not recommended for long-term use due to potential side effects, especially in older adults. Instead, natural sleep aids such as melatonin, L-theanine, CBT, exercise, and diet adjustments can help improve your sleep quality without the same risks associated with antihistamines.
Melatonin
Melatonin is a hormone that is naturally produced by the body in response to reduced light exposure, helping to promote sleep. However, exposure to artificial light from electronic devices can prevent its release, making it difficult to fall asleep. Taking melatonin supplements of 1 to 3 milligrams two hours before bedtime can help regulate your sleep-wake cycle, especially when dealing with insomnia, jet lag, or adjusting your sleep schedule. It is recommended to use melatonin short-term and consult a healthcare provider if sleep issues persist.
L-Theanine
L-theanine is an amino acid found naturally in green and black tea, as well as certain types of mushrooms. It has been shown to improve mental focus and promote better sleep quality by influencing serotonin, dopamine, and cortisol levels in the brain. A daily dosage of 450-900 mg for 8 weeks has been associated with improved sleep satisfaction, particularly in individuals with generalized anxiety disorder.
CBT (Cognitive Behavioral Therapy)
CBT-I is a recommended first-line treatment for insomnia that focuses on cognitive and behavioral interventions. It aims to change unhelpful thoughts about sleep and establish healthy pre-sleep habits through relaxation techniques such as breathing exercises and meditation. CBT-I also educates individuals about the impact of diet, exercise, and sleeping environments on their sleep quality. Typically, treatment involves 6-8 sessions, but the length may vary depending on individual needs.
Exercise
Engaging in at least 30 minutes of moderate aerobic exercise can improve sleep quality by increasing the amount of slow-wave sleep you get. Exercise helps stabilize your mood, reduce stress, and decompress the mind, making it easier to transition to sleep. However, it is important to time your workouts right, as exercising too close to bedtime may interfere with sleep due to the release of energizing endorphins. Aim to finish your workout at least 1-2 hours before bedtime to allow your body and mind to wind down.
Diet
A balanced diet is essential for overall health and can also impact your sleep. While specific dietary recommendations may vary, some natural sleep aids include warm milk, chamomile tea, and tart cherry juice. Warm milk is believed to contain chemicals that simulate the effects of tryptophan in the brain, promoting sleepiness. Chamomile tea is thought to contain flavonoids that interact with benzodiazepine receptors in the brain, aiding the sleep-wake transition. Additionally, tart cherry juice may support melatonin production and enhance your sleep cycle.

Safety concerns: cognitive impairment, risk of dementia, Alzheimer's, parasomnias
Allergy medications can cause drowsiness, but they may not be the best solution to help you sleep. Long-term use may lead to harmful side effects, especially in older adults.
Some allergy medications can cause cognitive impairment and increase the risk of dementia and Alzheimer's disease. A 2021 review of 14 studies found that anticholinergic medications, including antihistamines, increased the risk of dementia and Alzheimer's disease, with higher exposure increasing this risk. Anticholinergic drugs block acetylcholine, a neurotransmitter important for brain functions like learning and memory. Diphenhydramine (Benadryl), a first-generation antihistamine, has been associated with an up to 54% increased risk of dementia. Multiple studies have found that diphenhydramine impairs cognitive functions such as alertness, working memory, psychomotor speed, reasoning, and computation. Other studies have found no increased risk of dementia from antihistamines.
If you are concerned about the risk of cognitive impairment, dementia, or Alzheimer's, consider alternative allergy medications such as topical nasal sprays and allergy shots, or non-drug treatments such as cognitive behavioral therapy (CBT). It is always a good idea to discuss your options with a medical professional.
I found no information on parasomnias in relation to allergy medications.

Diphenhydramine: a sedating antihistamine, long half-life, potential side effects
Diphenhydramine is a sedating antihistamine that has been used since 1946 to treat allergies. Its sedative properties have also led to its use as a sleep aid, with many companies marketing it for insomnia under different brand names. However, it is important to note that diphenhydramine has a long half-life, which is the time it takes for the drug's effects to reduce by half. This half-life is 9 hours in adults and 13.5 hours in elderly individuals, meaning that the drug's effects are still active long after a person wakes up. This can cause grogginess, confusion, and memory loss, especially in older individuals.
The long-term use of diphenhydramine and other sedating antihistamines may lead to harmful side effects, including an altered mental state, dry mouth, urinary retention, constipation, blurred vision, and a drop in blood pressure upon standing. These side effects can pose health risks, especially for older adults. Additionally, antihistamines can lead to sleepwalking and other parasomnias. Anticholinergic antihistamines have also been linked to an increased risk of dementia and Alzheimer's disease, with higher exposure correlating with a higher risk.
While diphenhydramine may provide short-term relief from insomnia, it is not recommended as a long-term solution due to the potential side effects and health risks. Instead, it is advisable to consult a physician to determine the most suitable medication or treatment for sleep difficulties. Cognitive behavioral therapy (CBT), for example, is recommended by the American Academy of Sleep Medicine as a first-line treatment for insomnia. Improving sleep hygiene, such as using the bed only for sleep and avoiding television or screen time in bed, can also help improve sleep quality.
If you are considering taking diphenhydramine or any other antihistamine as a sleep aid, it is important to consult your doctor first to discuss the potential benefits, risks, and alternative treatments. Additionally, it is worth exploring natural sleep aids, such as melatonin or L-theanine, and making lifestyle changes, such as regular exercise and a balanced diet, to improve sleep quality.

Allergies can significantly impact sleep quality, with allergic rhinitis causing symptoms like sneezing, an itchy or runny nose, and watery eyes, leading to insomnia and other sleep disturbances. While antihistamines and over-the-counter sleep aids may induce drowsiness, they are not recommended for long-term use due to potential side effects and limited research on their effectiveness.
Steroid Nasal Sprays
Nasal corticosteroid sprays are a common treatment for allergic rhinitis, helping to alleviate symptoms such as congestion, a runny nose, sneezing, itching, and swelling of the nasal passageway. They are generally safe for adults, including pregnant women, and some are even suitable for children aged two and older. Regular use is recommended for optimal results, and they are most effective when started at the beginning of pollen season. Before using a nasal corticosteroid spray, it is advisable to consult a healthcare provider, who can recommend a suitable type and daily schedule.
Saline Nasal Flushes
Saline nasal sprays are another safe and effective option for treating allergy symptoms. They can be used to cleanse the nose, removing thick mucus, debris, and allergens like pollen, thereby relieving congestion. Saline nasal sprays are available over the counter or can be easily made at home. They are generally safe for adults and children, but it is recommended to consult a doctor for children under four. Hypertonic saline solutions may be more effective in improving nasal symptoms but may also cause mild irritation.
Improved Sleep Hygiene
- Use air purifiers to clear bedroom air of allergens like mold, dust mites, pet dander, and pollen.
- Keep windows and doors closed to prevent allergens from entering the home.
- Use blackout curtains to block outside light.
- Minimize noise or use a white noise machine to block unwanted sounds.
- Exercise regularly during the day and maintain a balanced diet.
- Consider natural sleep aids like melatonin or L-theanine, but always consult a doctor first, especially if you are pregnant or nursing.
