Cetirizine 20 Mg For Sleep

Histamine And Sleep Relationship

Cetirizine 10 mg Overview | Includes Use, Dose, Side Effects, and Alcohol

Before we delve any deeper we have to understand what role histamine plays in our sleep. Sleep is a complex process that involves numerous neurotransmitters. Among them Histamine is considered a master wakefulness-promoting neurotransmitter, exhibiting high activity during waking hours, decreasing in activity during the non-REM sleep, and is at its lowest during REM sleep. It is safe to say that histamine acts a stimulant.

Next question is what controls histamine levels in circulation and what controls histamine levels at night? This gets very complicated but if I had to simplify this into a short theory it would be like this: there is a gate-keeper in our brain which controls the release of histamine necessary for our normal sleep/wake cycle. The released histamine does its job and is subsequently broken down by our liver. During sleep time the gate-keeper should be signaling for low histamine levels to allow our brains to shut off. If you want to study this in detail, read: How Sleep Works Neurological Mechanisms Of Sleep.

Thing is, histamine also comes from food. It is degraded by the gut and the leftovers are broken down by the liver. If either the gut, the liver or both are compromised you might start circulating extra histamine in your system without the gatekeeper having any say over it.

The Main Ingredient In That Fast

Its the active ingredient in Benadryl, an antihistamine meant to treat symptoms of an allergic reaction like itchiness, watery eyes, and sneezing. The sleepy part is really just a side effect listed on the box.

Histamine is a chemical that produces the inflammatory response behind allergy symptoms, but it also plays a key role in promoting wakefulness. So, along with soothing allergy symptoms, when antihistamines counteract the histamine in your body, they have the side effect of making you feel tired, Rafael Pelayo, M.D., a sleep specialist with the Stanford Sleep Medicine Center, tells SELF.

But this ingredient wont necessarily knock everyone out. David Rapoport, M.D., director of the Sleep Medicine Research Program and professor of pulmonary and sleep medicine at the Icahn School of Medicine at Mount Sinai, tells SELF that these drugs arent very powerful as sleep aids. A 2017 review of the research in the Clinical Practice Guideline for the Pharmacologic Treatment of Chronic Insomnia in Adults examined 46 studies in an attempt to recommend clinical guidelines for treating insomnia. The researchers determined that the evidence behind DPH-based drugs leading to better sleep were clinically insignificant, suggesting that people shouldnt try to use these medications to fall asleep more quickly or stay asleep longer.

Frequently Asked Questions About Zyrtec

Does Zyrtec-D cause trouble sleeping?

It can. If taken too close to bedtime, some people find Zyrtec-D makes it hard for them to get to sleep. The best way to prevent this is to take your dose in the morning or in the early afternoon.

Can Zyrtec-D help with a cough?

Zyrtec-D doesn’t relieve chest congestion or directly treat a cough, but it can help with post-nasal drip. Post-nasal drip is when you have mucus from your nose drip down to your throat. This can also cause a cough. Antihistamines and decongestants can help stop this draining into your throat and then relieve your cough.

What is the difference between Zyrtec-D and Mucinex DM?

Zyrtec-D and Mucinex DM both have “D” in their name which may make them sound similar, but they actually don’t contain any of the same medications. Mucinex DM contains guaifenesin and dextromethorphan , while Zyrtec-D contains cetirizine and pseudoephedrine . Mucinex DM is better for coughs and chest congestion, and Zyrtec-D is better for sneezing, itchy/watery eyes, and a stuffy nose.

Will Zyrtec-D raise my blood pressure?

It can cause a temporary rise in your blood pressure. This is usually only a concern for people who have high blood pressure . If you have high blood pressure, avoid Zyrtec-D unless you’re following directions specifically given to you by your healthcare provider.

    Histamine And Its Receptors

    Histamine is produced as a biological amine from L-histidine through the action of histidine decarboxylase. Histamine-producing cells include histamine neurons, gastric enterochromaffin-like cells, mast cells, and basophils . The action of histamine is exhibited through four types of histamine receptors ) and is related to neurotransmission, smooth muscle contraction, vascular permeability, gastric acid secretion, basophil functions, etc. . H1 receptors, to which antihistamines for allergy treatment mainly bind, are distributed in various cells, such as central nervous system cells, smooth muscle cells , endothelial cells, chondrocytes, hepatocytes, dendrocytes, monocytes, neutrophils, and lymphocytes . Incidentally, antihistamines targeting H1 receptors are not structurally related to histamine they are inverse agonists binding to receptor sites that are different from those of histamine . Precise information on histamine and its receptors can be obtained from the web site of IUPHAR/BPS Guide to Pharmacology .

    Pharmacological Studies Of Cetirizine In Patients With Ar

    Several studies have investigated the pharmacological effects of cetirizine in patients with AR. An early study by Watson et al. evaluated the pharmacokinetic and pharmacodynamic properties of cetirizine 5 or 10 mg daily for 5 weeks in children with seasonal AR , using a randomized, double-blind, and parallel-group study design. The authors demonstrated that cetirizine was absorbed rapidly at both the 5- and 10-mg doses which were similarly and significantly effective in suppressing the mean histamine-induced wheal and flares, 1-24 h after the first dose, an effect maintained over the entire study period. Similarly, the symptoms and signs of AR were suppressed throughout the study, with no patient reporting sedation, dry mouth, or any other adverse effect at either dose of cetirizine investigated.

    When Should A Person Use Sleeping Pills

    The best time to take melatonin will depend on the nature of the sleep problem:

    • Sleeping pills for insomnia: A person with insomnia should take a sleeping aid, which includes valerian and sedative antihistamines, just before or at bedtime.
    • Sleeping pills for jet lag: Melatonin is a good option if tackling jet lag. Take melatonin several hours before the intended bedtime every day throughout the trip and a few days afterward.
    • Sleeping pills for shift work: Melatonin may also be the best option for people managing shift work. Taking melatonin at the end of a shift can help prepare the body for bed.

    Who Should Take Sleeping Pills

    When a person has insomnia, they may have trouble falling or staying asleep, wake up too early, or not feel refreshed upon waking.

    However, many people may not need sleeping pills to treat insomnia. Lifestyle adjustments, such as exercising and avoiding alcohol and nicotine, can often improve a persons sleep cycle and prevent insomnia. Changing the sleep environment, such as replacing an old mattress, might also help.

    If making these adjustments does not help treat severe insomnia, a sleeping pill may be a good short-term solution.

    There is a range of sleeping pills available to buy, including supplements and other over-the-counter medications. Anyone with ongoing insomnia should consult their doctor about the best approach.

    In a 2-year carcinogenicity study in rats, cetirizine was not carcinogenic at dietary doses up to 20 mg/kg . In a 2-year carcinogenicity study in mice, cetirizine caused an increased incidence of benign liver tumors in males at a dietary dose of 16 mg/kg . No increase in the incidence of liver tumors was observed in mice at a dietary dose of 4 mg/kg . The clinical significance of these findings during long-term use of cetirizine hydrochloride is not known.

    Cetirizine was not mutagenic in the Ames test, and not clastogenic in the human lymphocyte assay, the mouse lymphoma assay, and in vivo micronucleus test in rats.
