Odactra vs Allergy Shots
Introduction
For individuals suffering from allergies, there are certain treatments that can help manage symptoms and even decrease sensitivity to allergens over time. Odactra and allergy shots are two such treatments often prescribed for people with allergic reactions, specifically those caused by house dust mites. Both work by exposing the body to a small amount of the allergen in order to build up tolerance.
Odactra is a type of sublingual immunotherapy (SLIT), which involves placing a tablet under the tongue where it dissolves and gets absorbed into your system. It's highly convenient as it can be taken at home after the first dose is administered under medical supervision.
Allergy shots or subcutaneous immunotherapy (SCIT), on the other hand, involve regular injections given at a doctor's office typically over three to five years. The advantage here lies in its broader application as these shots can be customized to treat multiple allergies simultaneously unlike SLITs like Odactra that only target specific allergens.
What is Odactra?
Odactra, a tablet taken orally to treat dust mite allergies, is the first drug of its kind and represents an important advancement over traditional allergy shots. The FDA approved Odactra in 2017 as a treatment for house dust mite-induced allergic rhinitis with or without conjunctivitis. It acts by inducing tolerance to allergens, essentially “trapping” them in the body and reducing their ability to trigger allergic reactions. It's typically prescribed for adults aged 18-65 years who suffer from these specific types of allergies. The major advantage of Odactra is its selective influence on allergen-specific T cells which results in it having fewer side effects than traditional allergy shots that tend to have broader systemic effects.
What conditions is Odactra approved to treat?
Odactra is approved for the treatment of various allergic conditions, specifically:
- House dust mite-induced allergic rhinitis, with or without conjunctivitis.
- It's recommended usage extends to adults aged 18 through 65 years.
Unlike traditional allergy shots which require injections at a healthcare provider's office, Odactra provides its dose in tablet form that dissolves under the tongue.
How does Odactra help with these illnesses?
Odactra works to manage allergy symptoms by helping the body become accustomed to allergens. It does this by exposing the immune system to small, gradually increasing amounts of an allergen—in this case, house dust mites—so that over time, the body becomes desensitized and less likely to react with allergies. Allergies are caused when your immune system responds abnormally to harmless substances like pollen or dust mites. This response often involves histamine release from certain cells in the body resulting in symptoms such as sneezing, itchy eyes and a runny nose. Odactra's mechanism of action is believed to involve modification of the immunological response responsible for these allergic reactions. Therefore, by promoting tolerance against house dust mites through its sublingual tablet form (dissolved under the tongue), Odactra can significantly reduce allergy symptoms and improve quality of life for patients suffering from house dust mite allergies.
What is Allergy Shots?
Allergy shots, also known as immunotherapy, are a long-term treatment that decreases symptoms for many people with allergic rhinitis, allergic asthma, conjunctivitis (eye allergy) or stinging insect allergy. They work by reducing your sensitivity to allergens over time via regular injections of increasing amounts of the allergen(s). The mechanism involves an increase in levels of specific antibodies and changes in immune system cells that help block the allergic reaction. Allergy shots have been used since 1911 and can provide relief when avoidance measures do not control symptoms and medications are insufficient or cause unwanted side effects.
Compared to Odactra - an under-the-tongue tablet designed to treat house dust mite allergies - allergy shots have a broader spectrum and can be customized to treat multiple allergies simultaneously including pollen, mold spores, pet dander and even some food allergies. This versatility offers benefits especially for those who suffer from multiple allergies where single-allergen treatments such as Odactra may not be sufficient. However, like all medical treatments they come with potential risks including local reactions (such as redness at the injection site) or systemic ones like hives or wheezing which need immediate medical attention.
What conditions is Allergy Shots approved to treat?
Allergy shots, also known as immunotherapy, are a long-term treatment option that decreases symptoms for people suffering from allergies. These shots are typically used to treat:
- Severe seasonal allergies when over-the-counter medications aren't sufficient
- Allergic asthma
- Life-threatening reactions to stinging insects such as bees and wasps
- Long-term allergic rhinitis (hay fever)
- Sensitivities or allergies towards certain indoor allergens like dust mites and pet dander
How does Allergy Shots help with these illnesses?
Allergy shots, also known as immunotherapy, play a similar role to Odactra in managing allergies, particularly those related to dust mites. However, they function quite differently and offer some distinct advantages. Allergy shots work by gradually desensitizing your immune system to the allergen over time using controlled exposure. This can lead not only to fewer allergy symptoms when you encounter that allergen in the future but also long-term benefits even after treatment has ended. While Odactra is specifically designed for dust mite allergies and involves taking a daily tablet under the tongue, allergy shots can be customized to treat multiple allergens at once - including pollen, mold spores, animal dander or insect stings- making them more versatile in their application. Given this flexibility along with their proven longevity of effect after completion of therapy; allergy shots are often recommended when patients do not respond adequately to typical oral medications such as antihistamines or corticosteroids.
How effective are both Odactra and Allergy Shots?
Both Odactra and traditional allergy shots have proven effective in managing symptoms of dust mite allergies. They were approved by the FDA around 40 years apart, with allergy shots being available since the early part of the 20th century and Odactra receiving approval in 2017. The two treatments work on similar principles but are delivered differently: allergy shots involve regular injections to build up tolerance over time, while Odactra is an under-the-tongue tablet taken daily.
The effectiveness of Odactra was evaluated through double-blind placebo-controlled studies that showed significant improvement in nasal and eye symptoms for patients suffering from house dust mite-induced allergic rhinitis/conjunctivitis. Similarly, a meta-analysis review on subcutaneous immunotherapy (allergy shots) revealed substantial benefits for individuals with allergic rhinoconjunctivitis.
A clinical trial conducted in 2016 demonstrated that individuals taking Odactra experienced a decrease in combined score assessing both symptoms and medication use compared to placebo. In terms of safety profile, most commonly reported adverse reactions included throat irritation or pain, mouth edema, ear pruritus, upper abdominal pain amongst others; however severe systemic reactions were rare.
On the other hand, research indicates that allergy shots can provide long-term symptom relief even after discontinuation - a clear advantage over many pharmacotherapeutic options including antihistamines or corticosteroids which only control symptoms temporarily while they are being used. Nonetheless, due to its convenience as oral treatment without need for frequent doctor visits has made it appealing choice among people who cannot commit to allergen injection schedules or fear needles. However efficacy data supporting shot-free desensitization remains slightly less robust than those for traditional immunotherapy.
At what dose is Odactra typically prescribed?
Odactra is a once-daily allergy tablet that dissolves under the tongue to treat house dust mite allergies. The initial dose should be taken under medical supervision, but subsequent doses can be taken at home. For adults aged 18-65 years, one tablet per day is recommended. It's important to note Odactra may not show immediate results and it needs to be used continuously for around eight weeks before assessing its effectiveness.
Allergy shots (immunotherapy), on the other hand, typically start with injections given 1-2 times a week with gradually increasing doses (build-up phase) until reaching a maintenance level which usually takes about three to six months. Once the effective therapeutic dosage is reached, the frequency of allergy shots reduces to once every two-to-four weeks. The length of treatment varies from person to person depending on how they respond but generally lasts between three and five years.

At what dose is Allergy Shots typically prescribed?
Allergy shots treatment typically starts with a build-up phase, which involves receiving injections with increasing amounts of allergens one to two times per week. The length of this phase generally ranges from three to six months. After the build-up phase, there's the maintenance phase where the frequency of allergy shots decreases to once every 2-4 weeks. During the maintenance phase, you'll likely begin noticing a reduction in your allergy symptoms. If after a year in the maintenance phase no noticeable improvement is seen, your doctor may suggest discontinuing treatment or adjusting dosage regime and/or allergens being treated.
What are the most common side effects for Odactra?
Common side effects associated with Odactra can include:
- Nausea
- Itching in the ears and mouth
- Swelling of the mouth and tongue
- Throat irritation
- Dry mouth
- Headache
- Chest tightness or discomfort
Conversely, allergy shots (immunotherapy) might cause slight swelling or redness at the injection site. Other potential reactions encompass:
- Sneezing, nasal congestion, hives
- A drop in blood pressure (hypotension)
- Wheezing
- Shortness of breath
In rare cases, both treatments may trigger a severe allergic reaction known as anaphylaxis. If you observe any signs of anaphylaxis such as trouble breathing, fainting or facial swelling after starting these therapies, seek immediate medical attention.
Are there any potential serious side effects for Odactra?
While both Odactra and traditional allergy shots are designed to help build up your body's tolerance to allergens, they can also cause potential side effects that you should be aware of:
- An allergic reaction: While it is rare, you could have a severe reaction to either treatment. Symptoms might include hives; difficulty breathing; swelling in your face, lips, tongue or throat.
- Local reactions: This includes redness, itching or swelling at the place where the shot was given (only applicable for allergy shots), mouth and throat irritation (for Odactra).
- Systemic reactions: More generalized symptoms may occur such as sneezing, nasal congestion or hives. In more severe instances this could escalate into wheezing or trouble breathing.
- A drop in blood pressure: Rarely some people may experience lightheadedness or loss of consciousness due to a sudden decrease in blood pressure.
If you notice any signs of these potentially serious side effects during your course of immunotherapy with either Allergy Shots or Odactra tablets under-the-tongue (sublingual) therapy, get medical attention immediately.
What are the most common side effects for Allergy Shots?
Allergy shots, known as immunotherapy, can potentially cause a variety of mild to moderate side effects. These include:
- Redness, swelling or irritation at the injection site
- Sneezing, nasal congestion or runny nose
- Watery, red or swollen eyes
- Nausea and stomach discomfort
- Headaches and dizziness
- A feeling of tightness in the chest and difficulty breathing It should be noted that severe reactions are extremely rare but possible; these may include hives across the body, severe shortness of breath and even anaphylaxis. If you experience any signs of a strong reaction after receiving your allergy shot, seek immediate medical attention. The comfort level with each treatment varies among individuals; some people report few side effects while others decide to stop taking them due to uncomfortable symptoms.
Are there any potential serious side effects for Allergy Shots?
While Allergy Shots are generally safe, they can lead to serious side effects in rare instances. Signs of a severe reaction include:
- Difficulty breathing or swallowing
- Swelling in your face or throat
- Hives, itching, redness at the injection site
- Rapid heart rate
- Dizziness and loss of consciousness
- Severe stomach pain or vomiting
These symptoms may occur during an office visit for your shots or hours later. If you experience any of these symptoms after receiving allergy shots, it's important to seek medical attention immediately. Remember that while allergy shots can provide long-term relief from allergens, they're not without risks and should be administered under a healthcare professional's supervision.
Contraindications for Odactra and Allergy Shots?
Both Odactra and allergy shots, also known as immunotherapy, are treatment options for certain allergies. If you notice your allergic reactions worsening or if you experience severe adverse effects such as difficulty breathing or swelling of the throat after starting these treatments, seek immediate medical help.
Neither Odactra nor allergy shots should be taken if you have uncontrolled asthma or a history of severe systemic allergic reactions. Always inform your healthcare provider about any medications you're taking; certain drugs like beta-blockers can affect the body's ability to cope with serious allergic reactions from these treatments.
Allergy shots typically require frequent clinic visits initially for administration and subsequent monitoring for possible side effects. On the other hand, Odactra is a tablet that can be self-administered at home but needs to be taken daily.
It's important to remember that both treat only specific types of allergies: traditional allergy shots can target various allergens while Odactra is specifically designed for house dust mite allergies. As always, consult with an allergist before deciding on which form of treatment is right for your individual circumstances and health profile.
How much do Odactra and Allergy Shots cost?
For the brand name versions of these allergy treatments:
- The price for a monthly supply of Odactra, which is taken daily, averages around $300. This works out to approximately $10/day.
- Allergy shots pricing varies widely depending on factors like geographical location and insurance coverage. An estimation would be between $25 to $150 per shot. Depending on your required dose (most people start with weekly injections), it can range from about $6-$40/day.
If you're in need of frequent allergy shots (i.e., multiple times per week), then Odactra may cost less on a per-day treatment basis. However, as frequency decreases over time with maintenance therapy for allergy shots, this cost could reduce significantly. It's important to note that cost should not be a primary consideration in determining which one of these allergy treatments suits you best.
No generic version exists either for Odactra or traditional immunotherapy through allergy shots at present – both are specialized therapies tailored towards individual allergen sensitivities and require medical supervision during administration.
Popularity of Odactra and Allergy Shots
Odactra, an under-the-tongue tablet for dust mite allergies, was approved by the FDA in 2017. It is one of a new class of drugs that can be used at home and tends to have fewer side effects than allergy shots. In its first few years on the market, Odactra has been slowly gaining acceptance among allergists and patients alike.
Allergy shots (immunotherapy), on the other hand, have been around for many decades. They are still considered a gold standard treatment for allergies because they target multiple allergens at once and provide long-lasting relief after completing a course of therapy. Allergy shots require frequent office visits initially but become less frequent with time as maintenance doses are reached. These injections remain very popular due to their proven efficacy across multiple types of allergies including environmental allergens like pollen or pet dander besides dust mites.
Conclusion
Both Odactra and allergy shots have been proven effective in managing house dust mite allergies, with numerous clinical studies and meta-analyses indicating that they are more successful than placebo treatments. In some instances, these therapies may be utilized simultaneously, but this should be done under a physician's careful supervision due to potential interactions. Their mechanisms of action differ: while allergy shots function through gradually increasing exposure to allergens to build up immunity over time, Odactra delivers a consistent dose of the allergen extract via a daily tablet taken under the tongue.
Allergy shots typically require frequent visits to an allergist for administration initially before tapering off over time whereas Odactra can be conveniently taken at home after the first dose is safely administered in a healthcare setting. This represents significant convenience especially for patients who cannot frequently visit their healthcare provider.
Like all medications, both treatments require an adjustment period; benefits may not become apparent immediately as it takes time for heightened immunity against dust mites to develop.
The side effect profiles are similar between these two treatment options - most commonly including local reactions such as redness or swelling at injection sites with allergy shots or oral itching or mild mouth sores with Odactra tablets. However, rare systemic reactions like difficulty breathing can occur with either therapy necessitating immediate medical attention. As always when starting new therapies for allergies, patients must monitor their symptoms closely and seek prompt help if they notice any worsening of allergic symptoms.
