Molluscum contagiosum is a viral infection that affects the skin. It is caused by a poxvirus and results in small, raised bumps that are usually white, pink, or flesh-coloured. These bumps mostly appear on the face, neck, arms, and hands but can also pop up on any other part of the body as well. The virus spreads through direct skin contact or by coming in contact with objects that are contaminated, like towels or toys. Although the condition is generally harmless and the bumps usually go away on their own, treatment can help speed up the process and prevent the virus from spreading.
What is Cantharidin?
Cantharidin is a substance that comes from an insect called the blister beetle. When used as a treatment for molluscum, it helps to dissolve the skin bumps. This action helps the bumps to heal and eventually disappear.
How is Cantharidin Cream Used?
A doctor applies cantharidin cream to the clean skin using a small stick. The treated area is usually covered for a few hours. Within 24 hours, a blister forms on the treated area. Healing typically occurs within seven days. Treatments are often repeated every two to four weeks until all the bumps are gone. It is important to note that cantharidin should not be used on the face or groin areas.
Doctor's Supervision is Necessary
Patients cannot take cantharidin cream home to apply themselves. Only a doctor should perform this treatment. After applying the cream, a small blister will form where the treatment was applied. The molluscum bump should disappear as the blister heals. Sometimes, there can be scarring, but it is not very common.
Effectiveness of Cantharidin Cream
Even though cantharidin is a popular treatment, its effectiveness can vary. A recent study involved 94 children with molluscum contagiosum. They were divided into groups: some received cantharidin with a cover, some without, and others received a placebo (a treatment that doesn't do anything) with and without a cover.
Results showed that after six weeks, 42% of children who had cantharidin with a cover had their molluscum bumps completely disappear. For those who had cantharidin without a cover, 30% saw complete clearance. Only 8% of children who had the placebo with a cover and 14% without a cover had their bumps disappear. A detailed analysis showed that cantharidin was more effective than the placebo, with 36% of those treated with cantharidin seeing complete clearance compared to 11% in the placebo groups.
Another study looked at 300 children treated with cantharidin without a cover. It found that 90% of the children had their bumps cleared, and 8% had improvements even if all the bumps did not disappear. On average, it took two visits to the doctor to achieve complete clearance. Most parents were happy with the treatment, and 95% said they would choose cantharidin again for their child.
Side Effects of Cantharidin Cream
Using cantharidin cream can cause some side effects. These include temporary burning, pain, redness, and itching. Some children may also experience darkening of the skin where the cream was applied, but this usually goes away after a few months. In rare cases, scarring can occur.
While cantharidin cream is widely used for treating molluscum, its effectiveness can vary. Some studies show good results, while others show only a slight improvement over a placebo. More research is needed to fully understand how well it works. If you think cantharidin cream might be right for treating molluscum, talk to your doctor. They can help you decide the best treatment plan.
Preventing the Spread of Molluscum
To stop the molluscum contagiosum from spreading, it is important to practice good hygiene. Here are some tips:
Avoid Touching the Bumps: Do not scratch or pick at the bumps, as this can spread the virus to other parts of the body.
Keep the Affected Area Covered: Use a bandage or clothing to cover the bumps, especially when around other people.
Wash Hands Regularly: Make sure to wash hands with soap and water, after touching the bumps or applying treatment.
Avoid Sharing Personal Items: Never share towels, clothing, or any other personal items with others, as these can spread the virus.
Clean and Disinfect Surfaces: Clean and disinfect the surfaces that may come into contact with the virus, such as toys and gym equipment.
Talking to Your Doctor
If you suspect that you or your child has molluscum contagiosum, it is important to see a doctor for a professional diagnosis. A doctor can help with the best treatment option based on the patient's condition and the location of the bumps. They can also provide advice on how to stop the spread of the virus and manage any side effects from treatment.
Conclusion
Cantharidin cream is a popular treatment for molluscum contagiosum, but its effectiveness can vary. Some studies show that it works well, while others suggest only a slight improvement over a placebo. Despite this, many parents and doctors continue to use cantharidin cream because of its ability to clear the bumps. If you are considering cantharidin cream as a treatment, it is important to discuss it with your doctor to determine if it is the right option for you or your child.
