Drug Allergy - What All Should You Know?

A drug is used to treat a health issue or a disease, but it can rarely happen that the drug itself can cause an allergic reaction. Read on to know more about important things you must know about drug allergy.

What leads to a drug allergy?

The body’s immune system identifies any trigger as an antigen and produces “antibodies” to fight the antigen. It can, however, rarely happen that the drug itself can turn out to be an antigen and trigger the production of antibodies. There is a slight difference between side effect and allergy caused by a drug.

While a side effect will be seen in almost any person who takes it, the allergic reaction to a drug is based on the person’s immune system. A weakened immune system has a higher chance of triggering a drug allergy. For instance, steroids have the side effect of increasing sugar levels, whereas penicillin causing anaphylaxis is an example of a drug allergy.

A side effect may sometimes be positive too; however, a drug allergy is almost always negative.

Another aspect also is to note that a drug allergy may disappear over a period of time.

Possible drugs causing allergies:

  1. Antibiotics like penicillin and sulfa drugs
  2. NSAIDs (nonsteroidal anti-inflammatory drugs)
  3. Chemotherapy drugs
  4. Aspirin

Kinds of drug allergies: While there are many drugs which can cause minor allergies like a rash, there are some which could have a life-threatening effect. Anaphylaxis, for instance, can be very dangerous, and if not immediately attended to, can even cause death. Most often though symptoms include irregular heartbeat, swelling, and difficulty breathing.

Treatment of drug allergies:
For mild drug allergies, if the drug is critical for improving health, then the doctor can choose to continue the drug and give another drug to control the reaction.

However, if the reaction is severe, then an alternate needs to be given so that the health is taken care of, without causing a severe allergic reaction. Some common agents used to treat drug allergies are listed below:

  1. Antihistamines: Most allergic reactions are associated with the release of increased amounts of histamine. Therefore, antihistamines are used which can be used to control symptoms like swelling, redness of eyes, itching, and rashes. These can be used as eye drops, nasal spray, creams, or tablets.
  2. Corticosteroids: Often used to control overall inflammation and used in managing symptoms related to airways.
  3. Bronchodilators: If there are issues relating to breathing and chest tightness, this class of drugs are used.

Be frank with your doctor and tell any reaction you might notice. When having future surgeries, including dental, let the doctor know about your allergy.  In case you have a concern or query you can always consult an expert & get answers to your questions!

Medications And Drug Allergic Reactions

All drugs carry within themselves the potential to treat and harm the skin. Side effects of medicines are a common phenomenon, with variation in the intensities. Sometimes they are minor and do not require medications; however at other times they may require urgent attention and treatment.

Some allergies caused due to medications that primarily affect your skin are:

  1. Itches and rashes: Sometimes your body may be allergic to certain type of medications. If these drugs are taken by you then the immune system treats them as foreign invasions and triggers a reaction against them. In certain cases, on consuming a drug that your body is allergic to, a kind of white blood cell called T cells expand. Itching, rashes on the skin are common repercussions in such a scenario.
  2. Swelling on the face and throat: Often it happens that, on being administered a medicine or an injection, you may experience severe swelling on face and throat. This is an extreme case of medicinal side effect and is commonly known as anaphylaxis. This must be immediately treated and brought to the notice of a trained doctor. 
  3. Blisters: This is also an important potential side effect of a drug. On being administered a drug, you may experience an erosion on the surface of lips and eyes as a reaction against it. Immediate treatment and a consult to the doctor is imperative if you experience these symptoms. 
  4. Swelling of the tongue: If you have high blood pressure and if you take angiotensin converting enzyme, a swollen tongue and persistent cough are the possible side effects. 
  5. Flushing and itching: You may suffer from symptoms of flushing and itching as a possible side effect of the intravenous dyes that are used in the X-rays.

Possible Causes Behind Allergy!

Allergies are the result of the immune system’s response to foreign objects such as pet dander, pollen, certain foods, bee venom etc. In response to the allergen, the immune system produces antibodies, anticipating that the allergen is harmful in nature, even though that might not be the case always. The immune system can inflame the digestive system, skin, airways or sinuses when it comes in contact with allergens. The severity of allergies can vary from anaphylaxis to a minor irritation. In most cases, allergies cannot be fully cured. It, however, can be controlled with medication.

What are the symptoms of allergy?

  1. Various allergies cause different kinds of symptoms.
  2. Hay fever can cause sneezing, fluffy nose, itching of the eyes, nose, and mouth, swollen eyes etc.
  3. Food allergy can cause hives, mouth tingling, anaphylaxis, body itching etc.
  4. Insect sting produces symptoms such as anaphylaxis, cough, swelling on the source etc.
  5. Drug allergy can result in a rash, wheezing, swelling of the face, hives etc.
  6. Atopic dermatitis often lead to flake, itching, and reddening of the skin.
  7. There are other allergies that are triggered either by food or by insect bite. These can lead to a medical emergency known as the anaphylaxis. Some symptoms include skin rash, loss of consciousness, weak pulse, vomiting and nausea, shortness of breath etc.

What are the possible causes of allergy?

  1. Air:  A number of allergies occur from the surrounding air. Examples of such airborne allergies include pollen, animal dander, mould etc.
  2. Food items: Certain foods are known to be causing allergy such as tree nuts, eggs, peanuts, soy fish etc.
  3. Medication: There are medications such as penicillin-based antibiotics that can lead to allergy.
  4. Insect bite: Bite from insects such as wasp or bee can trigger an allergy in adults and kids.

What are the possible complications?
Allergy often leads to complication such as asthma, infection of the lungs, sinusitis, infection of the ear and anaphylaxis. The risk of getting these conditions increase, provided no treatment is done for a long duration.

How is the diagnosis done?
To investigate the type of allergy a person has, the doctor might ask for the exact symptoms that a person is encountering. He may ask questions related to intake of food and the possible triggers. A skin test is often performed, followed by a blood test to confirm the presence of allergy in an individual.

What are the methods of treatment?
Depending on the type of allergy one has, a doctor might prescribe nasal spray, eye drops, and pills to reduce the symptoms. Apart from this, if the allergy is severe in nature, a doctor might suggest going for immunotherapy and emergency epinephrine. Certain lifestyle changes and food habits go a long way in cutting down the symptoms.

Symptoms and Causes of Allergies

Allergies, or allergic reactions, are common occurrences, which are caused by unnatural reactions between your body's immune system and foreign substances, which have gained access into the body. When these substances, known as allergens, enter your body, your immune system produces antibodies, which are responsible for warding off unwanted substances like harmful viruses or diseases and helping in the body's overall resistance.

However, when antibodies identify a particular allergen as harmful, when it really isn't, a reaction occurs which may lead to inflammation or infection of the skin, sinuses, the digestive tract and the respiratory tract, among others. Allergies usually differ from individual to individual and can vary from mild skin irritations to fatal life-threatening emergencies.

Symptoms
Symptoms of allergies depend upon a wide range of factors, which are subjective and vary from person to person and from allergen to allergen. Depending upon the type of allergen involved and the nature of the allergy, symptoms may include any of the following:

  1. Sneezing
  2. Running nose
  3. Severe itching
  4. Swollen or red and watery eyes
  5. Hives
  6. Rashes
  7. Facial swelling
  8. Wheezing
  9. Flaky skin which can peel off

These symptoms are common in mild to moderate allergies, such as atopic dermatitis, hay fever, drug or food allergies. There are certain rare cases (say, scorpion stings), however, in which the allergic reaction turns out to be potentially life-threatening. This type of reaction is known as anaphylaxis. Here are its signs and symptoms:

  1. Intense shortness of breath
  2. Lightheadedness
  3. Nausea and vomiting
  4. Loss of consciousness
  5. Skin rashes
  6. Weak pulse
  7. A significant drop in blood pressure

Causes
The main cause of allergy is the uncontrolled reaction between the immune system's antibodies and harmless allergens. Allergic reactions are triggered when antibodies, like histamine, come into contact with particular types of allergens. These may include:

  1. Airborne allergens: Pollen, mold, or dust mites
  2. Insect stings: Bee stings or scorpion stings
  3. Certain eatables: Peanuts or sea food
  4. Medications: Penicillin or penicillin-based antibiotics
  5. Latex: Latex or other substances,  which are responsible for causing allergic skin reactions

A Penis Rash May Develop Due to Fixed Drug Eruption!

A Penis Rash May Develop Due to Fixed Drug Eruption!

Many men begin their daily penis examination during their morning shower, and one of the last things they want to discover as the water cascades across them is a penis rash that wasn't there when they went to bed. Kudos are certainly due to these men for making penis health the priority it deserves to be; now they need to figure out what might be causing this unwelcome penis rash. That's why it's good to know about a fixed drug eruption and its relationship to a penis rash.

Fixed drug eruption

A fixed drug eruption is an allergic reaction to a particular medication or medications. If a person is allergic to multiple drugs and is taking them at the same time, multiple fixed drug eruptions may occur. The term "eruption" refers to the fact that the allergic reaction shows up on the skin in the form of lesions - or "erupts" onto the skin.

Most often, these lesions are round or oval patches of swollen skin, typically reddish in color at the start but often changing to brown or purple. There may be a blister accompanying the lesion, typically staying within the area of the lesion.

Why is it called a "fixed" drug eruption? The fixed refers to the fact that the lesion tends to show up in the same general area whenever the drug is taken. However, it should be noted that, with repeated use, the lesions may also start showing up on other parts of the body. So if a fixed drug eruption is first noticed on the penis, it may continue to recur there, but it may also show up on the lips, the hands, the feet, etc.

The lesions

In most cases, lesions will appear between 30 minutes to 8 hours after administration of the drug. Often one lone lesion will appear at first. With repeated doses of the drug, it may either grow larger or more lesions may appear. Over time, especially after cessation of the drug, the lesions will "scab over." In most cases, they will disappear altogether at some point after the drug is no longer taken.

When the lesions are in a group, it may give the appearance of a penis rash. If solitary, it may seem more like a blister or blemish. In either case, it tends to be unattractive. More importantly, it gives the appearance of something contagious and possibly infectious.

In fact, penis rash from a fixed drug eruption is neither contagious nor infectious. However, because it looks as if it could be, it can be off-putting to partners, who may wish to avoid touching the penis until the rash is gone.

Discomfort

The lesions can also cause some discomfort for the man on whose penis they reside. They can be itchy in some cases. For some, they make the skin feel tender, which may decrease a man's desire for or enjoyment of sex (whether with a partner or by himself).

Causes

There are many, many drugs that have been implicated in the appearance of a fixed drug eruption. These include many forms of aspirin, many antibiotics, non-steroidal anti-inflammatories, sedatives and quinine.

If a penis rash (or rash elsewhere on the body) results from a fixed drug eruption, a doctor should be consulted to determine if an alternative medication may be used that might not have this side effect.

As a fixed drug eruption heals and the penis rash goes away, the skin may be in need of repair. Once any blistering has disappeared, using a first class penis health crème (health professionals recommend Man1 Man Oil, which is clinically proven mild and safe for skin) may help. The skin may need to be rehydrated so that it regains elasticity and suppleness. Using a crème with a combination of a natural moisturizer (such as vitamin E) and a high-end emollient (like Shea butter) will produce better results. Also important: Be sure the crème includes vitamin C, due to the role it plays in proper collagen production.

Penis Pain: Fixed Drug Eruption or STI?

Penis Pain: Fixed Drug Eruption or STI?

When a man experiences some penis pain and then discovers a sore on his manhood, he may become anxious for his penis health. After all, doesn't that situation seem like it could be describing an STI? Certainly, it must be some health issue, but it could be due to a different cause, such as a fixed drug eruption. Learning the characteristics of certain penis health issues can help ease a man's worries until he can visit a doctor and get an informed and definitive answer.

What is a fixed drug eruption?

Essentially, a fixed drug eruption is a way of describing a specific allergic reaction to a particular drug. When a person takes a medication to which they are allergic, it may cause a reaction in one of several ways (itching, hives, sneezing, etc). With a fixed drug eruption, it means that a round or oval shaped lesion will appear. Typically, it is reddish in color although it may shade into brown or purple. The lesion will usually turn into an ulcer, which is tender to the touch.

When the fixed drug eruption appears on the manhood, it usually is accompanied by some penis pain, itching or burning; the burning sensation is more likely to occur during urination.

Although many fixed drug eruptions occur within a day or two of taking a drug, in some cases it may be up to two weeks before lesions appear. Ceasing the drug that causes the eruption may cause the sore to go away; in other cases, steroids may be recommended.

STI?

That description sounds an awful lot like an STI, at least on the surface. And because it is crucial to correctly identify causes of penis health issues, it's important that a physician be consulted to verify exactly why this lesion has occurred. However, that said, there are some reasons why this description indicates a fixed drug eruption rather than certain STIs.

- Syphilis. Take syphilis, for example. One of the most-feared social diseases, syphilis causes about 100,000 deaths worldwide each year - and newly infects about 6,000,000 people annually. One of the most common clinical characteristics of syphilis is a lesion on the penis. However, that lesion is typically much "harder" than the one involved in a fixed drug eruption. Additionally, penis pain is not a common characteristic with syphilis.

- Herpes. Genital herpes are also characterized with lesions; however, with herpes, the sores tend to be smaller and more numerous. They also tend to cluster, whereas fixed drug eruption lesions (when they are multiple) may not appear in an obvious grouping. The herpes lesions are also not pigmented in the same way. There is, however, a similar tendency to penis pain and itching.

- Chancroid. Chancroid is a penis health concern not just for itself but because it can also make a person more vulnerable to HIV infection. With chancroid, the ulcer can be more painful than with a fixed drug eruption. The coloration is much different, typically yellowish-gray, and turning to black when tissue cell destruction is complete. In addition, swelling of lymph nodes can create a swollen and sore area in the midsection.

- Gonorrhea. Gonorrhea often presents with no symptoms; however, when it does, ulcers are not among its common symptoms.

Once a physician has determined the cause of the sore, proper treatment can be initiated.

Whether caused by a fixed drug eruption or other causes, penis pain is not something most men look forward to. Keeping the member healthy through the daily use of a superior penis health crème (health professionals recommend Man1 Man Oil, which is clinically proven mild and safe for skin) can help with normal penis pain situations. A crème with soothing moisturizing abilities is especially desirable, so select one with both a high-end emollient (think Shea butter) and a natural hydrator (vitamin E is good). In addition, it pays to find a crème with vitamin D, the so-called miracle vitamin, which is beneficial for fighting diseases and improving cellular function.

Common Myths about Allergy and Asthma

Allergy and asthma are very common in India and the Asian subcontinent. Allergies have a significant impact on quality of life.

Myth 1 Allergy-related diseases are uncommon

Reality: Incidence of allergy-related diseases have doubled in the past few decades.

1 in 3 people suffers allergies at some time in their life.
1 in 10 people are suffering from Asthma.
1 in 100 has life threatening allergy known as anaphylaxis.

Myth 2 Allergies are harmless

Reality: Allergies negatively impact the quality of life for example tiredness, irritability, poor quality of sleep, poor scholastic performance in children.

Allergies to food, drugs and insect sting can cause a severe systemic reaction that can lead to death.

Myth 3 Moving to another place can cure Allergies

Reality: Moving away from the source of allergen may improve your allergy symptoms. But these allergy symptoms reappear after some time as allergic peoples prone to develop new allergies.

Myth 4 All Children grow out of their Asthma


Reality: Asthma can persist; some children have asthma symptoms that improve or disappear during adolescence, whereas other will worsen. Severe or severe asthma tend to remain much the same as an adult.

Myth 5 Allergy drugs are dangerous and make you drowsy

Reality: Non-drowsy antihistamines are readily available, rarely make people drowsy.

Myth 6 Damp houses are just as healthy as dry houses

Reality: Damp houses have higher mould content than dry homes and indoor mould is a common cause of perennial allergic rhinitis, sinusitis, bronchitis as well as asthma.

Myth 7 Colours and preservatives are a common cause of asthma

Reality: preservatives like sodium metabisulfite (220,221,222) in wine,dried fruits,vinegar,grapes and some fruit salad can worsen,but do not cause asthma. Inhalation of small amount sulphur dioxide may cause a reflex contraction of your airways. Monosodium glutamate may trigger asthma in some people ,but researchers have shown that it is relatively a rare problem
