Answers about Antihistamine

Answers about Antihistamine

A cold can bring a variety of obnoxious symptoms that interfere with day to day lives. While there is no cure for the common cold, there are medications to help relieve the symptoms. The Cold FAid® kit is composed of many medicines to help lessen the duration and severity of symptoms. Antihistamines, commonly known as allergy relief, are an essential part of the Cold FAid® strategy for cold relief. 

Many resources show the benefits that antihistamines have on cold symptoms. The FDA lists antihistamines on their non-prescription drugs in order to relieve a runny nose and sneezing.  The study ‘Antihistamines for the common cold’ explored the effect of the drug to relieve symptoms. They studied adults and children with the common cold as well as the positive effects of antihistamines versus placebo pills. When comparing the benefits at the beginning, middle, and end of the cold, short-term effects were seen when the medications were taken on day one and two. Minimal benefit was found when taken in the middle or end of a cold. This study also found that the side effects such as sedation do not outweigh the benefits. 

Antihistamines work by stopping your body from releasing histamine, an inflammatory chemical. Histamine is most commonly known for causing allergic symptoms such as  a runny nose, watery eyes and sneezing. This occurs because the immune system misinterprets what can be a harmless substance such as food, dust, pollen as harmful. It then releases histamine upon contact with that allergen causing an allergic reaction. The blood vessels become leaky and weepy - causing the above noted symptoms. Antihistamines primarily stabilize the immune cells (mast cells, basophils, and eosinophils) that would otherwise release the histamine or invite inflammation.  

A study looked at how first- and second-generation antihistamines impact the common cold. When ingested, both types of antihistamines stop what are termed ‘histaminic’ receptors. However, only first-generation antihistamines pass through the blood-brain barrier and also affect the ‘muscarinic’ receptors. It is this neuropharmaceutical effect on the brain (theorized to be primarily in the medulla) that limits the symptoms of sneezing, rhinorrhea, nasal mucus, and occasionally coughs. Therefore, only first-generation antihistamines are effective. 

In addition, when treating a cold, first-generation antihistamines’ optimal therapeutic benefit is reached when they are used in conjunction with decongestants. Studies have shown that antihistamines work concomitantly with decongestants to provide significant short-term benefits for cold symptoms. 

In order to get back to ‘normal life’ sooner,  use your Cold FAid® kit. Let that antihistamine aid in reducing symptoms! Become healthier faster. 


Important Aspects of Zinc

Important Aspects of Zinc

As discussed in our previous blog, there are many benefits of zinc for shortening the length of a cold. In this blog, we will discuss the effects of zinc and COVID-19, important aspects to know about the supplement, and foods that contain zinc. 

Zinc supplementation for high-risk COVID-19 populations and COVID-19 patients is being studied. Based on the US National Library of Medicine National Institutes of Health, there is literature illustrating that it may be able to reduce lung damage and secondary infections particularly for older subjects with chronic diseases and other high risk groups. Continued studies and data are still needed to fully test the therapeutic effects for COVID-19.

In healthy individuals, zinc is a temporary supplementation, not an ongoing daily supplement without the oversight of a physician.  Regular use of zinc is to be taken at the advice of a physician to treat low zinc levels. Detrimental effects of sustained dietary zinc supplementation include copper deficiency, immune dysfunction, anemia, and decreased ‘good cholesterol’, as per the National Institute of Health.

Important things to know:  

  • Do not take zinc if you do not have symptoms as there is no evidence that it prevents colds. 
  • Intranasal zinc products were banned by the FDA in 2009. Zinc gel sprays and nasal swabs had caused people to have lost their sense of smell. Use of a zinc throat spray is not advised, notes Ted Cooperman, President ConsumerLab.com

Many foods provide natural sources of zinc. According to the National Institutes of Health, oysters, beef, crab, lobster, and baked beans have 2.9 or more milligrams of zinc. Poultry, pork, fortified breakfast cereals, and nuts also have zinc. Remember, the Recommended Daily Allowance (RDA) of zinc for women is 8 mg and for men is 11 mg. As noted in Harvard School of Public Health’s website, it is interesting to understand that legumes (such as beans, lentils, and peas) and whole grains have variably high zinc levels. Depending on the amounts of another essential mineral, phosphorous, in these foods, the zinc level may be lowered. Phytates (the collective term for food containing phytic acid or a phosphorus base) impairs zinc absorption. The amounts of phytic acid changes significantly even for the same food. It varies in reference to the seed type, environmental conditions, climate and soil, as noted in Harvard School of Public Health’s publication, The Nutrtition Source.

At Cold FAid®, we recognize the clinically proven value in using zinc supplements to help shorten the length of your cold and keep you healthy! 

Benefits of Zinc

Benefits of Zinc

When our founder, Julie Dickens, created Cold FAid®, her mission was to help provide an effective and efficient strategy for combating the common cold. Our strategy includes the use of 4 medications - zinc gluconate lozenges, antihistamine, nasal decongestant PE and a pain reliever. Within the next two blogs, we will be digging into the benefits of zinc.

Zinc is an efficacious homeopathic medication to treat a cold. How it works:  

  • First, a majority of colds are caused by rhinovirus.  
  • Zinc affects rhinovirus and certain other viruses. The Mayo Clinic writer, Bernt A. Bauer, M.D., along with many other researchers, theorize that zinc works by blocking the virus from
    • attaching to the cells lining the nose 
    • replicating if it enters a nasal cell. 

Lozenges should have 13 to 23 milligrams. The Best Health zinc lozenges used in the Cold FAid® kit contain 13.3 milligrams of zinc. To treat a cold, one lozenge every 2-4 hours is needed for a total of 6 lozenges per day. This delivers 79.8 mg (within the studied antiviral dose of over >75 mg/d).  While 40 milligrams per day is the recommended daily allowance (RDA) by the Food and Nutrition Board of the Institute of Medicine, Hallie Levine from Health.com mentions that exceeding the limit for three or five days is reasonable.

To fight a cold, suck on one lozenge every 2-4 hours at the first sign of a cold. Take the first lozenge within 24 hours of your symptoms beginning. While you may experience nausea or a metallic taste as side effects, the benefits result in a shorter and milder cold symptoms. Due to this, make sure to take a zinc lozenge after eating a meal as the lozenge coats your throat. Do not crush or swallow the lozenges whole. Citric fruits and citric juices deactivate the zinc if taken 30 minutes before or after. 

At Cold FAid®, we hope you and your families stay healthy this winter by reducing the length of your cold with zinc!
