DO NOT USE OIL BASED LUBRICANTS such as petroleum jelly, mineral oil and cold cream, as they may weaken the condom and cause subsequent failure of the product. So can some topical medicines, please contact your doctor or your pharmacist if you are unsure about the effect of any medications you’re using. Seek medical assistance as soon as possible, at least within 72 hours should a condom leak or burst during use. Do not use the condom if the rubber material is sticky or brittle or the individual container is obviously damaged.
