Condom Allergy or Irritation? Symptoms and How to Choose the Right Condom

Condoms are essential for preventing sexually transmitted infections (STIs) and for birth control. Today, many types of condoms are produced and available on the market in a wide variety of forms. They come in colorful designs, smooth or textured surfaces, scents, and fruit flavors, along with increasingly unusual shapes, and each type is designed with a different purpose in mind.

What is a condom?

The word "condom" comes from Latin and means a container that holds. Condoms are made from materials such as latex or polyurethane, and are worn over the penis. They are one of the most popular tools for preventing pregnancy and protecting against sexually transmitted infections. Today, many types of condoms are produced and available on the market in a wide variety of forms, including colorful designs, smooth or textured surfaces, scents, and fruit flavors, along with increasingly unusual shapes, and each type is designed with a different purpose in mind.

How many types of condoms are there?

• Latex condoms. The advantages are that they are inexpensive and easy to find. In addition to being effective at preventing pregnancy, they also protect against HIV and sexually transmitted infections. The disadvantage is that they can only be used with water-based lubricants. They should not be used with oils such as baby oil, cold cream, lotion, petroleum jelly, or any type of vegetable oil, because these cause the condom to break down and can make it tear during use.
• Natural-membrane condoms. This type makes up less than 5% of the market and is produced from sheep intestine. Unlike latex condoms, they have the advantage of working with all types of lubricant without breaking down. The disadvantages are that they are hard to find and not widely sold, and the animal membrane used to make them has tiny, invisible pores that viruses can pass through, so they do not protect against viruses such as HIV as well as latex condoms, even though they still block sperm and prevent pregnancy.
• Synthetic condoms, made from materials such as polyurethane or nitrile, make up about 15% of the market. Most internal condoms are made from these materials. The advantages are that they are less likely to cause allergies or irritation and, like natural-membrane condoms, can be used with all types of lubricant, while lasting longer. Besides being highly effective at preventing pregnancy, they also protect well against HIV and sexually transmitted infections, similar to latex condoms. The disadvantage is that they can be noisy from friction during use.

Advantages of using condoms

• Easy to buy and no prescription needed. Condoms are distributed at hospitals and in public places, and they do not have the side effects that come with women's birth control pills.
• They help prevent sexually transmitted infections, because semen, pathogens, and bacteria cannot pass through a condom, though viruses can still pass through condoms made from animal membrane.
• They allow sexual intercourse during a woman's menstrual period, sometimes called "running the red light" (though this is not recommended).
• They help protect women against cervical cancer.
• They are inexpensive and safer than other contraceptive methods. Wearing and using a condom correctly reduces the risk of pregnancy by up to 98%.
• With many shapes, scents, and colors, they can easily add to the pleasure of intimacy.

Condom allergy has two main causes

• An allergy to a coating on the condom, such as a lubricant. If you are allergic to the coating, switching to a different brand of condom may make the reaction go away.
• A latex allergy. At first there is often itching, pain, or burning, along with a hive-like rash or a thick red rash on the skin that touched the condom. In severe cases (which are very rare), some people may have difficulty breathing, airway spasms, and even fainting, lightheadedness, or seizures.

How to choose a condom

• Always read the label before buying. Reading the label tells you whether the product has been approved by the Food and Drug Administration, as well as other information such as the expiration date or the date by which it should be used.
• Choose the right type and size. In Thailand, condoms are commonly sold in sizes of 49 mm, 51 mm, and 52 mm. Choose a size that fits well so protection is as effective as possible, because the wrong size can cause the condom to break.
• Check the packaging and how the product is stored. Before buying, make sure the box is not damaged or torn, because the condom inside may be damaged and should not be used. The product should also be kept out of direct sunlight.
• Today many kinds of condoms are made and sold, but several have not been confirmed as safe by the Food and Drug Administration. Pay close attention to this, because instead of making sex safer, an unverified product could put you at risk.

If you suspect you are having an allergic reaction to a condom and it is mild, you can take an antihistamine or apply a topical medication. If it does not clear up after several days, see a dermatologist or a doctor who treats sexually transmitted infections. For most people, burning or itching of the genitals after using a condom is not actually a condom allergy but a yeast infection, herpes, or another sexually transmitted infection that has flared up or worsened after friction.
