Cautions

• Even though it may be rare, some people may have very bad and sometimes deadly side effects when taking a drug. Tell your doctor or get medical help right away if you have any of the following signs or symptoms that may be related to a very bad side effect:
• Signs of an allergic reaction, like rash; hives; itching; red, swollen, blistered, or peeling skin with or without fever; wheezing; tightness in the chest or throat; trouble breathing, swallowing, or talking; unusual hoarseness; or swelling of the mouth, face, lips, tongue, or throat.
• Avoid getting this medicine in your eyes, nose, mouth, rectum, vagina, or urethra.
• Avoid touching or allowing another person to touch the treated skin areas after you have applied the ointment.
• Avoid exposing treated skin to sunlight or artificial UV rays (sunlamps or tanning beds).
• Avoid using other medicine or skin products on the areas you treat with sinecatechins.
• Avoid sexual intercourse while you have sinecatechins on your skin. Wash off the ointment before intercourse, even if you are using a condom. Sinecatechins can weaken the latex in a rubber condom and it could break.
• Using this medicine will not prevent you from passing genital or anal warts to another person during skin-to-skin contact or sexual intercourse. Talk with your doctor about safe ways to prevent transmission of genital warts during sex.
