What is Zyclara?
Zyclara (imiquimod) is an immune response modifier.
Zyclara cream is a prescription medicine used to treat actinic keratosis (a condition caused by too much sun exposure) on the face and scalp of adults who are over 18 years of age.
Zyclara cream is also used to treat genital warts that appear on the outside of the body in adults and children who are at least 12 years old. This medicine is not a cure for genital warts.
Using too much Zyclara, or using it for too long can increase your risk of severe skin reactions. Follow your doctor's instructions.
Do not use Zyclara cream on areas of broken, wounded, or burned skin. Wait until these conditions have healed before using this medicine.
Before using Zyclara cream, tell your doctor if you have a weak immune system, an autoimmune disorder, graft-versus-host disease, or if you have recently received a bone marrow transplant or cord blood transplant.
When treating genital warts around the vagina, avoid getting the cream on the more sensitive inner layers of vaginal tissue. This could result in vaginal swelling or irritation and painful urination. Avoid exposure to sunlight or tanning beds. Imiquimod can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.
Zyclara ceam is not a cure for genital warts and it may not keep you from spreading this condition to others through vaginal, anal, or oral sex. You may develop new lesions during treatment with this medicine. For best results, keep using the medicine for the entire length of time prescribed by your doctor.
Zyclara cream will not protect against sexually transmitted diseases such as chlamydia, gonorrhea, herpes, HIV, syphilis, and trichomoniasis.
If you are treating the genital or rectal area with Zyclara, avoid sexual activity while the medicine is on your skin. Zyclara can weaken the rubber that condoms or diaphragms are made out of. If you use a condom or diaphragm for birth control, these items could break if the rubber weakens and an unplanned pregnancy could result.
