Side Effects vs. Allergic Reactions

kpprx1 • October 21, 2015

Side effects are expected results from taking medications. They are mild, short-term, and more of an irritation than a problem. There are many common ones that are expected and go away quickly or have easy fixes, such as taking with food or spreading out doses.

Nausea and vomiting, diarrhea, or stomach pain are common side effects, especially when they are being taken for the first time or on an empty stomach. Examples range from common drugs, like aspirin and ibuprofen, to antibiotics, such as Augmentin, used to treat infections. If these are the only symptoms, it may just be a sensitivity reaction and not an actual allergy. A true drug allergy is caused by chemicals processes in the body and produces a reaction with specific symptoms (listed below). Either way, caution should be used and consulting your Kearney Park Pharmacist would be beneficial.

Adverse (unwanted or unexpected) reactions to drugs are common and documented but different for each person. Almost any drug can have a negative effect on the body. Reactions range from mild side effects such as nausea and vomiting to life threatening shock to the entire body (anaphylaxis) or, even, death.

Anaphylaxis is serious emergency. It may be brought on by medication or something as simple as an insect bite/sting, pollen, or food. In some cases, the reaction can occur within seconds of exposure. There are signs and symptoms (listed below) that suggest this severe reaction is occurring, and, if so, requires immediate medical attention.

Symptoms

Drug allergy:

  • Itching of the skin or eyes (common) – some exceptions, including opioids
  • Skin rash/hives (common)
  • Wheezing

Anaphylaxis:

  • Swelling of the lips, tongue, or face
  • Difficulty breathing
  • Drop in blood pressure
  • Feeling the heart beat (palpitations)

Anaphylaxis may lead to death if left untreated for too long and should always be considered an emergency if a person appears to have the symptoms.

In many cases, the 1 st exposure/reaction is not as severe as the 2 nd and other subsequent times. The initial time, the body is attacking the cause but has not built strong defenses. If an allergic reaction is suspected at all, it is best to be cautious of the offending agent starting from the first time.  

Treatment

The goal of treatment for anaphylaxis and allergic reactions is to relieve symptoms and prevent further damage as quickly as possible.

Treatment may include:

  • Epinephrine (EpiPen) by injection to treat anaphylaxis
  • CPR (if heart stops)
  • Antihistamines (Benadryl, Zantac) to relieve mild symptoms such as rash, hives, and itching
  • Bronchodilator (Proventil, ProAir) for breathing symptoms (wheezing)
  • Corticosteroids (prednisone, hydrocortisone) to decrease inflammation and swelling

In some cases, the body may be desensitized to the offending agent. This treatment involves being given larger and larger doses of a medicine to improve your tolerance to the drug. The desensitization should be done by an allergist, who may also conduct tests to determine to what different things you may be allergic.

Testing

Skin testing may help diagnose an allergy to medications or certain foods. This is an indicator of how the body will react when exposed to different allergens.

Knowing whether a reaction is a side effect or an allergy is important with respect to medical care. It will determine what types of medications and materials need to be avoided when being examined and treated.

The evidence for low-dose atropine in pediatric myopia management has become difficult to ignore. Studies from the ATOM and LAMP trials have consistently demonstrated meaningful reductions in axial elongation at concentrations of 0.01% to 0.05%, with a favorable safety and tolerability profile that supports long-term use. As you integrate myopia management protocols into your practice, partnering with a reliable compounding pharmacy is one of the most important operational decisions you will make. Why Compounding Is Essential for This Treatment Category Low-dose atropine is not available as a commercially manufactured product in the concentrations most clinically utilized for myopia management. FDA-approved atropine formulations remain at 1% concentration, creating a significant gap between what the evidence supports and what is commercially available. Compounded atropine — prepared at 0.01%, 0.025%, or other prescribed concentrations — fills that gap. A 503A compounding pharmacy operating under USP 797 standards can prepare sterile, preservative-free atropine in unit-dose or multi-dose vials suitable for pediatric ocular use. What to Look for in a Compounding Partner Not all compounding pharmacies have the infrastructure or quality systems for sterile ophthalmic preparations. When selecting a pharmacy to compound atropine eye drops for your patients, verify that the pharmacy meets USP 797 sterile compounding standards, has an ISO-classified cleanroom environment, conducts sterility and potency testing, and offers shipping solutions that maintain product integrity. Kearney Park Pharmacy in Mesquite, Texas, compounds low-dose atropine under these standards and ships across the state of Texas with appropriate cold chain packaging. Streamlining the Prescription Workflow One of the most common barriers to incorporating compounded atropine into practice is the perceived complexity of the prescribing and ordering process. In practice, it does not have to be complex. Kearney Park Pharmacy accepts faxed prescriptions and works directly with patients on insurance questions and refill scheduling. We recommend providers clearly write the concentration, base vehicle, quantity, and refill authorization on the prescription to minimize callbacks. We also offer coordination with provider offices on prescription status and refill reminders. Concentration Selection and Monitoring Current evidence suggests that 0.05% atropine offers a stronger effect on axial elongation reduction compared to 0.01%, though with slightly higher rates of mild photophobia and accommodative effects. The LAMP2 trial data supports 0.05% as a viable first-line concentration in many patients. Clinical judgment regarding the starting concentration should incorporate the patient's baseline rate of progression, severity of myopia, and family history. Annual refraction and axial length measurements remain the standard for evaluating treatment response. Shipping Across Texas for Your Patients Many of your patients may not have convenient access to a compounding pharmacy near their home. Kearney Park Pharmacy provides shipping of compounded atropine eye drops directly to patients across Texas, making it easy for practices in Dallas-Fort Worth and beyond to offer this therapy without geographic limitations.

If your child has been diagnosed with myopia — commonly called nearsightedness — you may have heard their eye doctor mention low-dose atropine eye drops. For many parents, this sounds unfamiliar, maybe even a little alarming. But it is one of the most promising tools available today to slow down how quickly your child's vision worsens, and it all starts with a simple, nightly drop. What Is Myopia and Why Does It Progress? Myopia occurs when the eye grows too long, causing distant objects to appear blurry. It usually begins in childhood and can worsen steadily through the teenage years. Left unchecked, high myopia can increase the risk of serious eye conditions later in life, including retinal detachment and glaucoma. That is why eye doctors are increasingly focused not just on correcting vision with glasses or contacts, but on slowing down the progression itself. How Do Low-Dose Atropine Eye Drops Help? Atropine is a medication that has been used in eye care for decades, typically in higher concentrations to dilate pupils during exams. Researchers discovered that very low concentrations — often 0.01% or 0.025% — can slow the elongation of the eye without causing the side effects seen at higher doses, such as light sensitivity and blurry near vision. Multiple clinical studies have shown that low-dose atropine can meaningfully reduce the rate of myopia progression in children, making it one of the leading evidence-based options available today. Why Does My Child Need a Compounded Version? Low-dose atropine eye drops are not commercially manufactured in the concentrations used for myopia management. Standard atropine drops are made at 1% strength — far too strong for this purpose. That is where a compounding pharmacy comes in. Compounding pharmacies like Kearney Park Pharmacy can prepare atropine at the specific low-dose concentration prescribed by your child's eye doctor, in a sterile, preservative-free formulation that is safe for nightly use. The drops are made fresh, tested for sterility and potency, and carefully packaged to preserve quality. What Does Treatment Look Like? Most children use low-dose atropine drops once a day, typically at bedtime, in each eye. The routine is straightforward, and most kids tolerate it very well. Your child's eye doctor will monitor their prescription every six to twelve months to track whether the treatment is working. The goal is not to reverse existing myopia — glasses or contacts will still be needed — but to prevent the prescription from climbing higher and higher each year. Is It Safe? Low-dose atropine has a strong safety record in research studies involving thousands of children over multiple years. At the concentrations used for myopia management, the vast majority of patients experience minimal to no side effects. Your child's prescribing physician will be able to discuss whether this treatment is appropriate based on their age, prescription, and overall eye health. How Does Kearney Park Pharmacy Help? Kearney Park Pharmacy is a sterile compounding pharmacy located in Mesquite, Texas. We prepare low-dose atropine eye drops under strict sterile conditions, following USP 797 compounding standards.
