Do Allergy Pills Make You Sleepy

Take Your Allergy Medication In The Evening

Histamine: The Stuff Allergies are Made of

Antihistamines are a common and effective way to manage seasonal allergies, and modern allergy medicines are less likely to cause drowsiness than older antihistamines. However, some people may still feel tired after taking an allergy pill, especially if they havent taken one in a while.

To help reduce drowsiness and feel more alert during the day, take your daily antihistamine in the evening rather than first thing in the morning.

Consistency is also key to reducing the drowsiness caused by antihistaminesthe longer you take a daily allergy medication, the more easily your body will be able to tolerate those side effects.

Not all antihistamines are intended for daily use, so talk with your doctor before starting or changing any allergy medications to make sure its a good fit for you.

In General Using A Dph Product To Help You Fall Asleep Occasionally Is Fine But It Shouldnt Become A Habit

As long as you dont mind the potential next-day drowsiness, then sporadic use of the recommended daily dose of these drugs typically wont have serious medical repercussions for a healthy adult, Dr. Rapoport says. However, if you feel the need to turn to a sleep aid every night, you should seek treatment to address the underlying cause of your insomnia.

While its normal to have short periods of time where you cant sleep well , regularly having trouble falling or staying asleep is a sign that something deeper is going on. If you need to take something more than twice a week and the problem has gone on for more than three months, then you need to see someone, Dr. Pelayo says.

A primary care doctor or sleep specialist can help you identify any underlying conditions causing your urge to reach for something in your medicine cabinet, such as anxiety. Theres a pretty good chance that if you talk to somebody who knows what theyre talking about, we can find out whats going on, Dr. Rapoport says. Treating that condition can in turn help relieve the insomnia.

A doctor can also help you figure out if there are habits you may not realize are disturbing your sleep, like drinking tea late in the day, and help you work on establishing good sleep hygiene, like sticking to a consistent bedtime.

Allergies Can Worsen Sleep Apnea

Allergies can make certain sleeping conditions worse. Symptoms like inflammation and stuffy nose often cause you to breathe improperly, which can cause or worsen snoring and sleep apnea. When your airways are blocked or restricted, the lungs and even the heart struggle to get enough oxygen. The lack of air causes your body to wake itself up, interrupting your sleep sometimes hundreds of times in a given night. This explains the exhaustion that most people experience when suffering from sleep apnea, especially if allergies are making things worse.

Whats The Difference Between First

Just like the name implies, the first generation antihistamine were the first type approved by the Food and Drug Administration . They began to be approved in the United States in the 1930s and are still prescribed today.

They work on histamine receptor in the brain and spinal cord along with other types of receptors. Most notable about this generation of antihistamines is that they cross the blood-brain barrier, which results in drowsiness.

Second-generation antihistamines were approved by the FDA and first came to market in the 1980s. The second-generation antihistamines do not cross the blood-brain barrier to the extent that first-generation do and therefore do not cause drowsiness at standard dosage levels. Second-generation antihistamines are considered to be safer than first generation antihistamines because they dont cause drowsiness and interact with fewer drugs.

Transitions Between Prescription And Otc

As a general rule, over-the-counter drugs have to be used primarily to treat a condition that does not require the direct supervision of a doctor and must be proven to be reasonably safe and well tolerated. OTC drugs are usually also required to have little or no abuse potential, although in some areas drugs such as codeine are available OTC .

Over time, often 3â6 years, drugs that prove themselves safe and appropriate as prescription medicines may be switched from prescription to OTC. An example of this is diphenhydramine , an anti-histamine which once required a prescription but now is available OTC nearly everywhere. More recent examples are cimetidine and loratadine in the United States, and ibuprofen in Australia.

It is somewhat unusual for an OTC drug to be withdrawn from the market as a result of safety concerns, rather than market forces, though it does happen occasionally. For example, phenylpropanolamine was removed from sale in the United States over concern regarding strokes in young women. A study has been done examining consumer’s perceptions about the risk of and access to nonprescription medication. The study concluded that a small percentage of consumers prefer having access to medication over potential risks of taking non-prescribed medication.Ranitidine was suspended in multiple markets due to concerns over the presence of the carcinogenN-nitrosodimethylamine .

How Are Antihistamines Classified

Antihistamines are divided into two major subtypes. The first subtype is called H-1 receptor antagonists or H-1 blockers. This subtype of antihistamines is used to treat allergy symptoms. The second subtype is called H-2 receptor antagonists or H-2 blockers. They are used to treat gastrointestinal conditions, including gastroesophageal reflux disease , peptic ulcers, gastritis, motion sickness, nausea and vomiting. The naming structure tells doctors and scientists the cell type the location of the histamine receptor that the antihistamine medication blocks.

The H-1 blocker subtype is further broken down into two groups first-generation antihistamines and second-generation antihistamines.

The Immune Response Is Tough On Your Body

Allergies cause bodily inflammation, and when your immune system is inflamed, your body uses up a fair amount of energy and resources to make an immune response, says Kara Wada, M.D., an allergist and immunologist at The Ohio State Wexner Medical Center. Plus, when youre having an allergic reaction and histamines are released, that can make you feel tired, notes Dr. Monteleone.

Are There Other Things I Can Do If I Feel Drowsy During The Day

Hergert: Sure. I recommend practicing good sleep hygiene at night. That starts with a consistent sleep schedule, and you should avoid caffeinated drinks late in the day.

Also, if you take over-the-counter medications, try to avoid any that may contribute to drowsiness. And avoid alcohol while taking medication. It could make you even drowsier.

In addition to that, eat a healthy diet and make sure you get regular exercise but not too close to bedtime. A 30-minute walk is a good way to boost your energy. If you cant get outside, try walking around your house 2 or 3 times a day for 10 or 15 minutes each time. That can really help.

What Causes Allergies Anyway

How do allergy medications work?

An allergic reaction is a chain reaction that starts in your genes and is expressed by your immune system, according to the American Academy of Allergy Asthma & Immunology .

When you have an allergy to something, like pollen or grass, your immune system views it as an invader . It then overreacts by producing antibodies called Immunoglobulin E , which travel to cells that release chemicals called histamines, Dr. Monteleone explains. Cue the stuffy nose, coughing, sneezing, and other uncomfortable symptoms.

Why Do Antihistamines Make You Drowsy

16 December 2013

Drowsiness is one of the major side effects of some antihistamines, such as diphenhydramine and doxylamine succinate . And because of their powerful sedating qualities, antihistamines are also the active ingredients found in numerous over-the-counter sleep aids.

But why do antihistamines make you sleepy?

The story begins with histamines, which are chemical compounds that play a couple of roles in the body, though theyre best known for their involvement in the bodys local immune responses.

When you get injured or your immune system detects a potentially dangerous foreign substance, certain white blood cells and tissue cells release histamines that seek out and attach to other cells that have a histamine receptor.

Here, the histamines induce an inflammatory response they dilate the blood vessels, increasing blood flow to the site of injury or invasion. They also make blood vessels more permeable, allowing proteins and white blood cells to seep into the damaged or infected tissue.

But there are side effects to this healing process. For example, when youre fighting a cold , histamines widen the blood vessels in your nasal cavity, causing nasal congestion.

Additionally, the increased fluid leakage from your blood vessels, combined with an increased mucous production also caused by histamines can result in a runny nose.

Why Do Some Antihistamines Make You Sleepy

Sedation is a prominent side effect of older antihistamines, what we call first-generation antihistamines. Examples include:

The first-generation antihistamines can make you drowsy because they cross the blood-brain barrier, an intricate system of cells that regulates what substances pass into the brain. In fact, these older antihistamines are often marketed as sleep aids. The first-generation antihistamines are also used in cold-and-flu formulations to provide a side benefit of drowsiness when youre feeling ill and need plenty of rest.

Drowsiness is something to be aware of with first-generation antihistamines. They may increase the risk of falls or fracture in people 65 years or older. According to the Canadian Society of Allergy and Clinical Immunology, first-generation antihistamines are also linked to impaired driving as well as fatal car and flying accidents. These drugs can also cause dry mouth, constipation, and difficulty urinating.
