Use Of Benadryl While Pregnant

Does A Lower Heart Rate Mean You’re Fitter? | GTN Does Science

Allergies are pretty common during pregnancy. It is reported that 20-30% of women who are of childbearing age are affected by allergies, and in a subset of women, pregnancy can even aggravate some preexisting allergy symptoms such as allergic rhinitis. As a result, antihistamine drugs are often employed to treat these allergic symptoms. This gives birth to a question of whether the use of antihistamines or specifically Benadryl while pregnant is safe?

Although alternative methods, such as fluids and rest, should be attempted first to treat the; symptoms of allergies during pregnancy. First-generation antihistamines like Diphenhydramine are drugs of choice, especially during the first trimester, for the relief of allergy symptoms in pregnant women. The U.S. Food and Drug Administration lists Benadryl as category B, which means that the drug has failed to demonstrate a risk of birth defects or congenital anomalies to the fetus in animal reproduction studies but there are no adequate and well-controlled studies in pregnant women, OR, animal studies have shown adverse effects, but adequate and well-controlled studies in pregnant women have failed to demonstrate a risk of birth defects or anomalies to the fetus in any trimester.

The Faster The Heart Rate The Shorter The Lifespan

True: In a large study of people going for a health checkup in China, those who had a high-normal resting heart rate of 80 bpm to 90 BPM had a 40 percent shorter lifespan than those with a desirable heart rate of 60 BPM to 69 BPM.

However, the good news is that 15 minutes to 30 minutes of daily moderate exercise, such as brisk walking, could eliminate the increased mortality and reverse the life-span loss, the researchers say.

The study underlines;the important role that;physical activity can play in keeping your heart healthy and giving you a longer life, Dr. Laffin says.

Even moderate activity has benefits, he says. So there is no longer any reason to stay on the couch.

Melatonin And Cardiac Diseases

Melatonin induces multiple actions in various cardiac pathologies . In this paper, only relevant evidence in myocardial infarction, myocardial ischemia/reperfusion injury and heart failure is included .

Table 1. The effect of melatonin supplementation on cardiac diseases: animal studies.

Table 2. The effect of melatonin supplementation on cardiac diseases: human studies.

Melatonin supplementation protects the heart in several experimental models of myocardial infarction and myocardial I/R injuries . Tan and co-workers were first to demonstrate the beneficial effects of melatonin in isolated rat hearts subjected to cardiac I/R-induced arrhythmias: infusion of melatonin reduces premature ventricular contraction and ventricular fibrillation due to occlusion and reopening of the anterior descending coronary artery . This finding is also reported in other animal models of cardiac arrhythmias , confirming the therapeutic potential for melatonin in reducing the incidence of sudden cardiac death . Additional studies show that short-and long-term melatonin supplementation is cardioprotective in various in vivo and ex vivo myocardial models of I/R injury . In these studies, administration of melatonin before or after ischemia preserves the microstructure of the cardiomyocyte and reduced myocardial I/R injury as indicated by a reduction in myocardial infarct size .

Evidence For Cardiovascular Benefits Of Endogenous Melatonin And Melatonin Supplementation

A strong inverse relationship exists between endogenous melatonin levels and cardiovascular disease . Epidemiological studies report that both nocturnal melatonin synthesis and circulating levels are reduced in patients with coronary heart disease , hypertension , heart failure and cardiovascular risk conditions such as diabetes and obesity . Incidence for adverse cardiac events, including myocardial infarction , sudden cardiac death and cardiac arrhythmias increases in the early morning, when circulating melatonin levels are considerably lower . Similarly, low melatonin secretion levels are associated with a greater risk of incidence for myocardial infarction in women with increased body mass index , supporting the crucial role of endogenous melatonin in cardiovascular pathologies.

Solid evidence supports the beneficial effects of melatonin supplementation in various cardiovascular pathologies . Since the cardiovascular benefits of melatonin have recently been reviewed elsewhere , only the evidence for the benefits of melatonin supplementation in hypertension, pulmonary hypertension and ischemic heart disease is summarized below.

Oftentimes, the heart doctor may overlook this topic because there are so many other things that they must bring to the patients attention, Dr. Kaminski says.

His advice? If you have high blood pressure, atrial fibrillation, supraventricular tachycardia or congestive heart failure, you should avoid OTC medicines that contain a ;.

Dr. Kaminski specifically recommends against using pseudoephedrine.

Can Benadryl Be Used In Babies Or Toddlers If So What Are The Possible Side Effects

Over-the-counter forms of Benadryl shouldnt be used in babies or toddlers. This is because children younger than 6 years old have an increased risk of side effects from Benadryl.

Children can have the same side effects of Benadryl as adults, such as dizziness or drowsiness. But Benadryl can also cause more serious side effects in children, such as a fast heartbeat or seizures. The drug may also cause children to become more excitable or hyperactive.

You should never use Benadryl to help your child fall asleep. This can be very dangerous.

Due to these risks, you shouldnt give Benadryl to your baby or toddler without the direction of their doctor. If your child has symptoms of an allergy or cold, talk with their doctor about the best way to treat those symptoms.

Do Seniors Have A Higher Risk Of Side Effects From Benadryl

Yes, older adults likely have a higher risk of side effects from Benadryl than younger adults. This is because their bodies may get rid of the drug more slowly.

Older adults may have more side effects from Benadryl, including sleepiness, dizziness, or heart problems. Sleepiness and dizziness can increase the risk of falling, which can be very serious.

If youre an older adult interested in taking Benadryl, talk with your doctor. They may recommend that you take a lower dose of Benadryl to reduce your risk of side effects. Or they may suggest that you take a different medication to treat your allergy or cold symptoms.

Which Allergy Medications Affect My Blood Pressure

You should;avoid decongestants if you have high blood pressure;or heart problems. Decongestants constrict blood vessels to open nasal passages and facilitate breathing. Because decongestants constrict blood vessels throughout your body, they can worsen hypertension. Additionally, decongestants stimulate the release of norepinephrine in your body, which raises your blood pressure and your heart rate.

When choosing an allergy medication, be aware of combination products that contain decongestants. Products that contain a decongestant typically have the words;sinus,;cold,;congestion, or;;on the label. They may also be labeled with the letters;D, PD,;or;PE;after the name.

Examples of allergy medicines that contain decongestants include the following:

  • Allegra D
  • Benadryl D
  • Clarinex D
  • Claritin D
  • Sudafed Sinus and Allergy
  • Zyrtec D

The list above is a small sample of allergy medications that contain decongestants. Always check with your pharmacist before choosing allergy medications.

Dietary Melatonin And Pulmonary Hypertension

Pulmonary hypertension is associated with an increased oxidative stress and leads to right ventricle hypertrophy and cardiac fibrosis with the hallmarks of the heart failure . A single subcutaneous injection of monocrotaline induces pulmonary hypertension with RV hypertrophy and dysfunction, increase in interstitial fibrosis and plasma oxidative stress . In this model, a chronic dietary melatonin treatment reduces RV hypertrophy, improves RV function, reduces plasma oxidative stress and reduces cardiac interstitial fibrosis, therefore supporting the beneficial effects of curative and preventive treatments of dietary melatonin in pulmonary hypertension . These effects of melatonin are associated with a reduction in oxidative stress and an increase in enzymatic and non-enzymatic antioxidant capacity .

Should Exercisers Lay Off The Antihistamines

Pollen levels are high and you have a 10-K run ahead of you. Do you pop a couple of antihistamines to avoid an allergic reaction? Or not?

Sorry, a definitive answer is not provided here.

However, a newly published study from the UO lab of John Halliwill has raised such questions. The research found that 795 of 3,000 genes activated after vigorous exercise become blunted in their responses during a three-hour recovery period if exercisers had taken strong doses of antihistamines.

Audio: Halliwill’s personal take on using antihistamines during extensive exercise:

Halliwill, a professor in the Department of Human Physiology, discovered in 2005 that naturally occurring histamines in the body relax blood vessels, increasing blood flow that aids post-exercise recovery. That emerged from his original focus on why some people, including athletes, pass out after vigorous physical exertion. He later found a link between an overactivation of two histamine receptors to drops in blood pressure.

The new study led by doctoral student Steven A. Romero and in collaboration with Hans Dreyer, a departmental colleague who studies muscle physiology expanded the research to a wider genetics level. Researchers sequenced RNA, molecules essential for making proteins and sending signals among genes, with state-of-the-art equipment in the UO’s Genomics Core Facility.

The study is now online ahead of print in the Journal of Physiology. The NIH and American Heart Association supported the research.

Two Studies: Cbd Reduces Heart Inflammation

Vital Signs Nursing: Respiratory Rate, Pulse, Blood Pressure, Temperature, Pain, Oxygen

In this 2013 review of several studies , CBD was found to positively influence white blood cell survival and migration related to heart disease. The researchers concluded that A common theme throughout these studies is the anti-inflammatory and antioxidant effect of CBD. In the heart, in vivo CBD treatment protects against ischaemia-reperfusion damage and against cardiomyopathy associated with diabetes.

The second 2016 study published in the Journal of Molecular Medicine CBD reduced markers of inflammation in individuals with autoimmune myocarditis, a condition which causes inflammation of the heart.;

So, while its far too early to determine how exactly CBD influences cardiovascular function, there is promising evidence that CBDs known anti-inflammatory properties apply to the heart as well, and that CBD can potentially reduce heart-related inflammation.

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.

Detection In Body Fluids

Diphenhydramine can be quantified in blood, plasma, or serum.Gas chromatography with mass spectrometry can be used with electron ionization on full scan mode as a screening test. GC-MS or GC-NDP can be used for quantification. Rapid urine drug screens using immunoassays based on the principle of competitive binding may show false-positive methadone results for people having ingested diphenhydramine. Quantification can be used to monitor therapy, confirm a diagnosis of poisoning in people who are hospitalized, provide evidence in an impaired driving arrest, or assist in a death investigation.

Does Cbd Only Affect Heart Rate In Stressful Conditions

This suggests that CBD may only reduce heart rate if heart rate has otherwise been increased by; stressful conditions. This makes sense because increased heart rate and blood pressure is a result of autonomic arousal, aka the fight or flight response that is activated upon stress. Autonomic arousal is also the mechanism behind anxiety and panic attacks, and CBD is well-known as an effective anxiety reliever: one 2019 study in The Permanente Journal and another in the Journal of Neurotherapeutics both found that CBD reduced anxiety.;

So, CBD anxiolytic effects are likely related to its potential ability to reduce heart rate.;

Possible Benadryl Side Effects

The following are some known Benadryl side effects. Keep in mind that the actual side effects will differ from person to person. Some individuals may as well suffer certain side effects which are not necessarily listed here. Whether the side effects are mild or severe will depend on the dosage taken and other factors that may or maybe unknown.

  • ;;; Constipation
  • ;;; Blurred vision or any change in vision
  • ;;; Confusion
  • Test : Resting Heart Rate

    This is the simplest test we conducted: each day over a period of three days, at the same time each day, we measured my heart rate without CBD, and then I took a 40mg dose of NuLeaf Naturals organic full-spectrum CBD oil, we waited 30 minutes, and we measured my heart rate again. We then took the average of all three measurements. Here are the results:

    Day 1
    65 66.67

    As you can see, I did experience a modest reduction in heart rate after taking the CBD, though the reduction wasnt consistent and it wasnt outside the normal variation in my heart rate.;
