For most individuals dealing with vaginal dryness or pain from cancer and/or cancer treatments, the use of a vaginal moisturizer by itself does not entirely solve the symptoms. A vaginal lubricant can be used in addition to the vaginal moisturizer to help maximize the results. Unlike a vaginal moisturizer, lubricants are used right before engaging in sexual activity. The addition of a water-based or silicone-based vaginal lubricant can help decrease pain or irritation with penetration.  

How are vaginal lubricants used? 

• Most vaginal lubricants are clear, thin liquids that look and feel like vaginal secretions. 

• For vaginal penetration, spread a lot of lubricant around your vaginal entrance and vulva, as well as on your partner’s finger, the head of your partner's penis, or the tip of a sex toy if you are using one. 

• Keep your lubricant nearby in case you need to reapply during sex. 

• Communication with your partner about why you are using a vaginal lubricant may help with any concerns about incorporating this new product.  

How do I know which vaginal lubricant to use? 

• Try and find a vaginal lubricant that is pH balanced. This will help the vagina stay slightly acidic like the natural pH before menopause. 

• Try and avoid lubricants that have perfumes as they can irritate the lining of the vagina and vulva. 

• Some lubricants contain a preservative called glycerin. In some women, glycerin can increase your risk of vaginal yeast infections. 

• Avoid lubricants that contain oils or petroleum jelly (like Vaseline). 

• In certain cases, coconut oil may be used as a lubricant under physician guidance.  

• Water or silicone-based lubricants work well.  

• Water-based lubricants are safe to use with latex condoms or sex toys. 

• Silicone-based lubricants are safe to use with latex condoms but can damage silicone-based sex toys. 

• Many commercial water-based lubricants are outside of the limits for osmolality. A lubricant that is too high in osmolality will pull water from the cells and leave the lining dryer. Aim to find a product with 380 mOsm/kg or less. This is not an issue for silicone-based lubricants. 

• A minority of vaginal lubricants and moisturizers have gone through the process of getting 510K approval from the United States Food and Drug Administration (FDA). This type of approval means the product has gone through testing to show it is safe and does not irritate the vagina or vulva. 

Good to know: Vaginal lubricants do not protect against pregnancy or sexually transmitted diseases. 

Where can I purchase vaginal lubricants? Since vaginal lubricants do not require a prescription, they can be purchased over the counter. These products can usually be found in drugstores or online. Make sure to talk to your physician before starting any new vaginal lubricants.
