Infliximab And Rituximab : Recognizing Allergic Reactions
Any infused or injectable medication could possibly cause an allergic reaction .
But some medications may be more likely to cause reactions than others. Two common biologics to be aware of are infliximab and rituximab .
Infliximab is a commonly prescribed biologic that can cause allergic reactions in some patients. Symptoms of a reaction during or after the infusion include:
- A weak and rapid pulse
- Nausea, vomiting, or diarrhea
- Loss of consciousness
The CDC recommends that people who have had a severe reaction to the first vaccine not receive a second dose of that vaccine .
Those who had a non-severe immediate reaction to the first dose should also not receive a second dose, but your doctor may refer you to a specialist in allergies and immunology to provide more care or advice.
Ask your doctor if you should get the Johnson & Johnson vaccine if you are unable to get the second dose of an mRNA vaccine because of an allergic reaction to the first dose, per the CDC.
Should You Take Pain Relief Medications Such As Tylenol Or Motrin Before Getting The Covid
The U.S. Centers for Disease Control and Prevention does not recommend taking pain relief medication before vaccination. It is unknown if those medications will decrease the effectiveness of the vaccine.
For pain, discomfort or fever after the vaccine, you may take these medicines as long as you have no medical reason to avoid them.
What Should People With Allergies Know About Allergic Reactions To The Covid
In December 2020, health officials in the United Kingdom issued a very broad warning on the Pfizer-BioNTech vaccine because two people had adverse reactions to the vaccine. Initially they stopped giving the vaccine to people with a history of any severe allergies. But the U.K. Medicines and Healthcare products Regulatory Agency which is similar to the Food and Drug Administration later updated their guidelines. The UK recommendations are now similar to the U.S. recommendations and only people with certain allergies should not get the vaccine.
According to Dr. June Raine, MHRAs Chief Executive, Anaphylaxis is a known, although very rare, side effect with any vaccine. Most people will not get anaphylaxis and the benefits in protecting people against COVID-19 outweigh the risks.
In April 2021, the CDCs Advisory Committee on Immunization Practices, the FDA and the CDC paused the use of the J& J vaccine. The pause was based on extreme caution. There were reports of a rare and severe type of blood clot in individuals after getting their COVID-19 vaccine. During the pause, medical teams from the CDC and FDA examined the data to assess the risks. The two agencies determined that the J& J vaccine was safe and effective in preventing COVID-19 and should resume in the United States.
Only a very small number of allergic reactions about two to five people per 1 million to the vaccines have been reported. Most people have not had allergic reactions to the vaccines.

Aafa: What Do People With Allergies Need To Know About Vaccine Ingredients And Allergic Reactions
Dr. Matthew Greenhawt: The main ingredient I think people are suspicious of is something called polyethylene glycol or PEG. We eat this. It is in a decent amount of food. Orally this doesnt really cause problems, but injecting it was the one thing that came up and people zeroed in on that.
We have absolutely no causative data. We have absolutely nothing that says this did or didnt cause it. I dont see this as a risk for somebody with food allergy. This could be a general risk for reasons we dont know and that will emerge. Theres no egg. Theres no peanut.
There are a lot of reasons why people can have a reaction to a vaccine. Some of it can be non-allergic. Just because you had an adverse reaction, thats the larger umbrella, and allergy is a specific type of an adverse reaction. It happens through a very specific pathway.

Reasons To Avoid The Vaccine
Its recommended that if youve had an allergic reaction any of the ingredients in the vaccine, you should not get it. If you had an allergic reaction to the first dose of a COVID-19 vaccine, the CDC doesnt recommend getting the second dose. But overall, having allergies doesnt exclude you from getting the vaccine.

And If You Have Allergies Make Sure To Tell Staffers At The Covid Vaccination Site
If you’re one of the 50 million Americans who have allergies, according to the American College of Allergy, Asthma& Immunology, you should tell staffers at the COVID vaccination site. According to a Mar. 4 update from the CDC, the agency suggests “people get vaccinated even if they have a history of severe allergic reactions not related to vaccines or injectable medicationssuch as food, pet, venom, environmental, or latex allergies.” The same goes for people who have a history of severe allergic reactions or have a history of allergies to oral medications, the CDC explains.
For those with a history of a severe immediate allergic reaction to another vaccine, a contraindication to a different type of COVID-19 vaccine, or a history of anaphylaxis due to any cause, expect to be observed for 30 minutes after you get your shot. For anyone not in those three categories, a 15-minute observation period will be implemented, after which, you’ll be one step closer to building immunity to COVID-19.
Q& a With Aafa’s Medical Scientific Council
Now that the COVID-19 vaccine has reached the U.S., many people with asthma and allergies have questions about it. The Asthma and Allergy Foundation of America talked with three doctors on our Medical Scientific Council on Dec. 10, 2020, about the Pfizer-BioNTech COVID-19 vaccine. Please note this was recorded shortly before the FDA authorized the COVID-19 vaccines.
Here are a couple of the questions we asked the doctors and text excerpts from their answers. Please watch the videos below to hear their full answers.

What We Know So Far About Allergic Reactions To Covid
The FDA has issued emergency use authorization for three COVID-19 vaccines. The Pfizer-BioNTech vaccine, which has been recommended by the CDC for people age 16 and older, is 95% effective at preventing COVID-19 illness according to clinical trial results. The Moderna vaccine, which has been suggested by the CDC for people age 18 and older, is 94.1% effective.
A third vaccine, produced by Johnson & Johnson via Janssen Pharmaceutical Companies, was just recently approved for an Emergency Use Authorization by the FDA. In clinical trials, this vaccine was shown to be 66% effective in preventing moderate and severe COVID-19 disease 28 days after vaccination. Overall, the vaccine was also 85% effective in preventing hospitalization and 100% effective in preventing death, 28 days after vaccination.
The CDC has since reported that between Dec. 14 and Dec. 23, 2020, there were 21 cases of anaphylaxis after the administration of a reported 1,893,360 first doses of the Pfizer-BioNTech COVID-19 vaccine . Of these cases, 71% of these occurred within 15 minutes of vaccination.
Even though there is a risk of anaphylaxis, its still very small and the potential benefit from the COVID-19 vaccination clearly exceeds the potential for harm, says Dr. Lang. The situation is evolving, however, and well learn more as we gain more experience with these vaccines.
/13asthma And Allergic Medications
Allergies have been a talking point with the COVID-19 vaccines since it can make some prone to developing anaphylaxis, which is a worrisome, severe allergic reaction.
However, Dr Pandit says that most medications, or antihistamines used by those suffering from allergies have been found to be safe when used with the COVID-19 vaccine. “Vaccine is safe amongst those with food allergy and common allergic conditions like Asthma, Allergic Rhinitis and Allergic Dermatitis. Only people who have an Anaphylaxis to any of the vaccine contents, should NOT take the vaccine.”

Is It Okay For People With A History Of Allergies To Get The Vaccine
People with a history of allergies or allergic reactions can receive the vaccine. People who are allergic to any of the vaccines ingredients or had an allergic reaction to a first dose should not receive the vaccine. They should receive the vaccine at a medical facility where they can be monitored for 30 minutes post-vaccination. Learn more on our COVID-19 Vaccine Allergic Reactions page.
Should You Stop Taking Routine Medications Before Your Vaccination
According to Dr. Vyas, medications for blood pressure, diabetes, asthma and other common health conditions arent things to be concerned about.
The studies for the vaccines were done with a number of people who had many of these common conditions. If you have hypertension or another common medical condition, you can have a little more peace of mind knowing that they did studies and trials on the COVID-19 vaccines which included people with the same conditions. The good news is that they responded well to the vaccines. So, dont change any of your regular medications, she says.

COVID vaccines work to generate a robust immune response upon injection. The potential effectiveness of the vaccines may come down to how well your body responds to it.
For the ones suffering from comorbidities, a slow immune response may be a possibility, in some extreme cases. Usage of some drugs may also make the body ‘busy’, leading to a delayed immune response to the vaccine.
That being said, if you are someone enlisted to get the vaccine in the coming while, there are certain medicines and therapies which may make you want to double-check with the doctor or postpone an appointment right now.
If You Are Allergic To An Ingredient In A Covid
If you have had a severe allergic reaction or an immediate allergic reactioneven if it was not severeto any ingredient in an mRNA COVID-19 vaccine, you should not get either of the currently available mRNA COVID-19 vaccines .
If you have had a severe allergic reaction or an immediate allergic reaction to any ingredient in Johnson & Johnsons Janssen COVID-19 vaccine, you should not get the J& J/Janssen vaccine.
If you arent able to get one type of COVID-19 vaccine because you are allergic to an ingredient in that vaccine, ask your doctor if you should get a different type of COVID-19 vaccine. Learn about the different types of COVID-19 vaccines.

While COVID vaccines are still subject to ongoing research, doctors, right now, warn beneficiaries to comprehend the risk factors associated with some steroid medications.
Chronic steroids can be taken as needed. However, steroid injections and medications for other therapies which need to be taken regularly can pose problems. It’s best to consult with your healthcare provider first to know the right way to proceed with the vaccination.
Severe dose painkillers are also best avoided before vaccination, as they may cause unpleasant reactions. “Wait until after the vaccination to take a painkiller like ibuprofen or aspirin to make symptoms subside”, says Dr Pandit.
What Ingredients Are In The Vaccines
Heres a breakdown of whats in the three COVID-19 vaccines that have been approved for emergency use.
Pfizer BioNTechs COVID-19 vaccine ingredients
According to Pfizer, the Pfizer BioNTech COVID-19 vaccine is a messenger RNA vaccine was made with synthetic and chemically produced components as well as enzymatically produced components from naturally occurring substances like proteins. This vaccine does not have a live virus in it.
Inactive ingredients in the Pfizer BioNTech COVID-19 vaccine include:
- Potassium chloride.

Can You Take Otc Allergy Medications Before Or After The Vaccine
In short, yes. Over-the-counter antihistamines and nasal steroid sprays will not affect vaccine efficacy, says Purvi Parikh, M.D., an allergist with the Allergy & Asthma Network who specializes in infectious disease. So if you regularly rely on meds like Claritin, Flonase, or Zyrtec, you can keep taking themeven on the day of your appointment.
These medications help block your bodys reaction to allergens like pollen and dust, keeping swelling, itching, and congestion to a minimum they dont interfere with the production of antibodies spurred by the COVID-19 vaccines.
However, if you dont take allergy medications daily, the CDC advises against taking them to try to mitigate potential side effects before your shot .
You can take these medications to relieve post-vaccination side effects if you have no other medical reasons that prevent you from taking these medications normally, the CDC explains.
However People Treated For Autoimmune Conditions Produce Weaker Responses Than Healthy People
- Washington University School of Medicine
- Nearly 90 percent of people taking immunosuppressants to treat autoimmune conditions produce an antibody response to COVID-19 vaccination, but the response is weaker than those generated by healthy people, according to a new study.
COVID-19 vaccination elicited antibody responses in nearly nine out of 10 people with weakened immune systems, although their responses were only about one-third as strong as those mounted by healthy people, according to a study by researchers at Washington University School of Medicine in St. Louis.
The study, published Aug. 30 in the Annals of Internal Medicine, looked at people taking immunosuppressive medications to treat chronic inflammatory diseases such as inflammatory bowel disease and rheumatoid arthritis. Since a minimum level of antibodies needed for protection hasn’t been established, it has been difficult to say whether the levels achieved by people on immune suppressing drugs are high enough to protect them from severe COVID-19, the researchers said. The Centers for Disease Control and Prevention recently recommended that people taking immunosuppressants receive a third dose of the vaccine to strengthen their immune responses.
Nonetheless, the discovery that COVID-19 vaccination elicits a response in people with compromised immune systems — even if not quite as strong a response — is encouraging news for a population that faces a high risk of serious illness.

Will People Need A Covid
The U.S. Centers for Disease Control and Prevention has announced that COVID-19 booster shots for people who received both doses of the Pfizer/BioNTech and Moderna mRNA vaccines will be made available starting the week of Sept. 20. People are eligible to receive a COVID-19 booster shot eight months after they received the second dose of their vaccine.
Research shows that mRNA vaccines decline in effectiveness against infection over time. It continues to maintain strong protection against hospitalization, however.
The current protection against severe disease, hospitalization, and death could diminish in the months ahead, especially among those who are at higher risk or were vaccinated during the earlier phases of the vaccination rollout, says CDC Director Rochelle Walensky. For that reason, we conclude that a booster shot will be needed to maximize vaccine-induced protection and prolong its durability.
Its expected that people who received the single-dose Johnson & Johnson vector vaccine will also need a booster shot.
Dr Fauci Said Do Expect Some Side Effects Especially After The Second Dose
“If you are really having discomfort that usually would occur rarely after the first dose, you likely would get a pain in the arm and maybe a little bit of an ache, not very much of an issue there. That’s what I went through personally, when I got it,” he said. “But the second dose of either the Madonna or the Pfizer in some people do get about a 24 hours worth of achiness, maybe some chills, occasionally a fever, a headache. You feel under the weather, as it were taking something appealed to youlike two Tylenol, every six or eight hours or soI can see is going to have a major difference that might make you feel much better.”

Should I Stop Taking My Allergy Medicine Before My Vaccine Appointment
You dont need to stop taking your regular allergy medicines if youre getting the COVID-19 vaccine.
If every springtime you take your Zyrtec and use your nose sprays, absolutely you should continue taking those, says Shirley Fung, an allergy and immunology specialist at Jefferson Health. Theres no concern it will interfere with the efficacy of the vaccine.
If youre taking stronger, immune-suppression medications, like prednisone, talk to your doctor before getting vaccinated. The vaccine is considered safe if youre immunocompromised, but research is still underway on the efficacy of the vaccine for immunocompromised people.
Over-the-counter allergy medicines, like Zyrtec, Flonase, Claritin, and Allegra, however, dont require a discussion with your doctor. You may even want to set a reminder to take your medicine, especially if you see a high pollen count on the day of your appointment.
Obviously the benefit of getting your COVID vaccine as soon as possible is important, but if youre already stuffy and sneezy, and you add to that the potential of more side effects later, that might not feel good, says Scott Feldman, a physician and assistant professor of medicine in the section of allergy and immunology at Penn Medicine. You may want to take your maximum allergy medication to control your allergies if its a particularly bad day.
