For effective protection with Durex Invisible Super Ultra Thin Condoms, follow these steps: 1. **Check Expiry:** Always verify the expiry date on the individual wrapper. Do not use expired condoms. 2. **Open Carefully:** Tear the wrapper from the serrated edge. Be gentle and avoid using fingernails, teeth, or any sharp objects, as this can damage the ultra thin condom. 3. **Place Correctly:** Once the penis is erect, place the condom on the tip with the rolled rim on the outside. 4. **Squeeze Air:** Pinch the tip of the condom to remove any trapped air. This prevents air pockets that could cause the condom to break and leaves space for seminal fluid. 5. **Roll Down:** With the tip pinched, roll the condom down to the base of the penis. If it doesn't unroll easily, it might be inside out. Discard it and use a new one. 6. **After Ejaculation:** Immediately after ejaculation, while the penis is still erect, hold the rim of the condom firmly against the base of the penis and withdraw. 7. **Dispose Safely:** Carefully remove the condom from the penis and wrap it in tissue before disposing of it in a waste bin. Never flush condoms down the toilet. 8. **New Condom Every Time:** Use a new Durex Invisible Super Ultra Thin Condom for each act of sexual intercourse.

While Durex Invisible Super Ultra Thin Condoms are generally safe for use, potential side effects or issues can occur: - **Allergic Reactions:** Some individuals may have an allergic reaction to natural rubber latex, which is the primary material in these condoms. Symptoms can include itching, redness, rash, or swelling. If an allergic reaction is suspected, discontinue use immediately and consult a healthcare professional. Latex-free condoms are available as an alternative. - **Irritation:** Minor irritation may occur due to friction or sensitivity to lubricants or spermicides (if present). - **Breakage:** Although rare and rigorously tested, condoms can break or slip, which may reduce their effectiveness in preventing pregnancy and STIs. Factors contributing to breakage include improper use, damage from opening, using oil-based lubricants, or using an expired condom. - **Discomfort:** Improper fit or application can lead to discomfort during use. Always ensure correct application and check the condom for any damage before use to minimize risks.
