Sun Allergy (Photosensitivity)

Almost every person is at least slightly allergic to the sun. The symptoms vary from person to person, but the most common symptoms are a rash, hives, red, itchy, or watery eyes. The treatment for sun allergy is usually antihistamines or ointments to soothe the itching. In addition, certain medications, including NSAIDs (non-steroidal anti-inflammatory drugs) and Antipsychotics, can be used to treat it. However, these drugs are not always effective and can cause unwanted side effects.


Symptoms of sun allergy photosensitivity are typically a rash, redness, or itching. In severe cases, people may develop blisters, swelling, or hives. These skin reactions occur when the immune system reacts to UVA and UVB rays.

Photosensitivity can be triggered by sunlight, certain drugs, or diseases. The immune system makes an antibody called IgE. When IgE reacts with light, the body releases chemicals into the bloodstream. This chemical reaction is sometimes referred to as phototoxicity.

The best way to prevent photosensitivity is to wear sunscreen. A broad-spectrum sunscreen with an SPF of 30 or higher should be used. This will help prevent the rash from forming. You can also use sunscreen that blocks ultraviolet light.

Sun allergies can be treated with corticosteroids, which work to control the immune system. If the rash is severe, oral cortisone may be used. If the rash is mild, prescription antihistamines can be used.

Medications can also trigger an allergic response. Typical medications that cause a reaction include tetracyclines, which are used to treat urinary tract infections and respiratory tract infections. Some of these drugs can also make your skin more sensitive to the sun.

People who have an allergic reaction to sunlight should protect their skin by wearing a wide-brimmed hat, long sleeves, and sunglasses. It is also a good idea to cover your skin with a clear plastic mask.


Various factors can affect your exposure to UV radiation. These include your age, gender, skin type, and season. If you have a medical condition that makes you more sensitive to the sun, you may be at risk of developing a reaction.

Photosensitivity occurs when the immune system overreacts to sunlight. The body releases chemicals that cause a rash. If the rash is severe, it may spread to other areas. If you suffer from photosensitivity, you should avoid sun exposure as much as possible.

Symptoms of photosensitivity vary from mild to severe. Most reactions occur within the first 24 hours after exposure. The rash is usually itchy and red. Some people experience peeling and blistering. Some types of photosensitivity can result in permanent scarring.

Photoallergic reactions can also be triggered by medications, fragrances, and sunscreens. Your doctor may perform a skin patch test to help determine if you are allergic to sunlight.

If you are prone to developing photosensitivity, you should talk to your doctor about the rash. They can discuss ways to prevent new rashes from forming and to ease the itchiness. They may also review any medications that you are taking.


Symptoms of photosensitivity include itching, swelling, redness, numbness, blisters, and burning. They may also be accompanied by wheezing, nausea, and headaches.

Photosensitivity is an extreme sensitivity to ultraviolet radiation. It can be triggered by a number of factors, including genetics, medications, and medical conditions. In some cases, the reaction will clear up on its own. Depending on the underlying condition, however, treatment may be necessary.

Doctors can use several different techniques to treat photosensitivity. One method is to reduce the amount of sunlight on the affected skin. Another method involves using UV light therapy.

In some cases, a patient may need to take oral beta-carotene. This vitamin is essential for bone health. It also helps the immune system.

If a patient is experiencing a mild rash, antihistamines can be prescribed. In more severe cases, the doctor may prescribe a topical corticosteroid preparation. This can be used for hives and blotchy rashes.

Other remedies include ultraviolet (UV) light therapy, omalizumab, and histamine (H1) blockers. In some cases, phototherapy may be combined with a patch test. In this procedure, a small area of the skin is exposed to ultraviolet light. The patch is then removed after two days.


Medications can increase your sensitivity to the sun. In some cases, you may even experience an allergic reaction. The best way to prevent this is to avoid prolonged sun exposure and wear sunscreen on a daily basis.

If you are taking medications, talk with your healthcare provider about your responsibilities. He or she will review your medical history, current medications, and skin creams. The doctor will also determine if you are at risk for photosensitive reactions.

If you have an autoimmune condition, you may be more at risk for a photosensitive reaction. In addition, your body may be less able to regulate its own temperature, which can increase the risk.

Medications that may make your skin sensitive to the sun include antibiotics, antidepressants, blood pressure medications, and some acne treatments. Several drugs can also inhibit your body’s ability to cool itself.

If you take one of these medications, it’s a good idea to drink plenty of fluids to avoid dehydration. Another option is to wear a wet dressing on your affected area.

The photo-patch test is a simple way to detect if a medication causes a reaction. During the test, your dermatologist shines a light on different areas of your skin. If a reaction occurs, it’s a good idea to remove the patch.


Several different types of antimalarials are used to treat sun allergy photosensitivity. Depending on the nature of the reaction, the symptoms may range from mild redness to blistering. For more severe cases, topical cortisone creams or oral steroids may be needed.

There are two main types of photosensitivity: chemical and polymorphic light eruption (PLE). Both reactions can cause an itchy rash. PLE affects men and women aged 20 to 40, but can also affect children.

Typically, a chemical photosensitivity reaction occurs within 24 hours of exposure. The reaction usually resolves with the peeling of the skin. However, some medications can be absorbed through the skin, causing a stinging sensation and an itchy rash. The rash may appear anywhere on the body, but most commonly it is limited to the exposed areas.

The best way to avoid sun allergies is to stay out of the sun as much as possible. If you must be in the sun, use broad-spectrum sunscreen with an SPF of at least 30, and wear a wide-brimmed hat. If you have a medical condition, be sure to ask your doctor about special precautions for protecting yourself from the sun.

Antipsychotic medications

Several antipsychotic medications increase the body’s sensitivity to sunlight. It’s a good idea to ask your doctor about the risks associated with taking these drugs.

Antipsychotics can also increase the risk of heart rhythm problems. If you notice an irregular heart rate or pulse, talk to your doctor. This is particularly true if you are taking more than one of these drugs.

Some medications can also make you less thirsty. This can cause dehydration in hot weather. Some people who take these drugs have a higher chance of getting metabolic syndrome, a condition that increases the risk of heart disease.

Photoallergy is a medical condition that develops after exposure to the sun. When UV rays hit the skin, the shape of a molecule changes, causing an immune system response. It’s often called the “sun-sensitivity reaction.” The exact symptoms depend on how much you have been exposed. In some cases, it can be a painful, erythema-like rash.

A recent review included two reports of suspected drug-induced photosensitivity. This includes clozapine, tamoxifen, levothyroxine, colesevelam, and phenobarbitone.

The most important thing to remember is that you don’t have to be a sun worshipper to have a photoallergic reaction. It’s a good idea to wear sunscreen or sunglasses whenever you’re outside.

Polymorphous light eruption

Symptoms of polymorphous light eruption, a skin disease, include a rash that usually begins within a few hours of exposure to intense sunlight. It typically affects the upper chest, arms, and shoulders. The rash usually settles after a few days, but it may recur at some time in the future.

It’s important to avoid direct contact with the sun and to wear protective clothing and sunglasses. If the rash becomes very painful or bothersome, seek medical attention. There are medicines that can help reduce itching and swelling.

Some doctors may also recommend phototherapy. This is a treatment that uses ultraviolet A (UVA) or ultraviolet B (UVB) light to treat the rash. It involves exposing the skin to small doses of either light and subsequently testing the reaction. A positive reaction may be confirmed by a skin biopsy.

Patients with PMLE are at greater risk of developing vitamin D deficiency. To prevent this, they should use high-SPF sunscreen, and wear protective clothing. They should also try to stay in the shade or in a covered area when outdoors.

People who have a history of polymorphous light eruption are at risk of developing a second episode. It is important to avoid sunlight during the spring and summer when the disease is most likely to occur.
