Starting CPAP therapy is an important step toward managing obstructive sleep apnea, but many first-time users experience minor side effects during the adjustment period. The good news is that most of these issues are temporary and can often be managed with simple changes to your equipment or therapy routine.

One of the most common complaints is dry mouth or a dry nose. This can happen when airflow dries out the airways or when someone sleeps with their mouth open while using a nasal mask. Increasing the humidifier setting or using a heated tube may improve comfort. Some people also benefit from using a chin strap or switching to a full-face mask after discussing options with their healthcare provider.

Another frequent concern is mask leaks. A poorly fitted mask can allow air to escape, making therapy less effective and creating noise that disrupts sleep. Regularly checking the mask fit, adjusting the headgear, and replacing worn cushions can help maintain a proper seal.

Some users notice redness or pressure marks on their face after wearing the mask overnight. This may indicate that the mask is too tight or not the correct size. Using mask liners, trying a different cushion style, or consulting a CPAP supplier for a better fit can improve comfort.

Bloating or swallowing air, known as aerophagia, may also occur in some people. If this becomes frequent, it is important to discuss it with a healthcare provider, who may recommend adjusting pressure settings or enabling comfort features such as ramp mode.

Although these side effects can be frustrating, they rarely mean that CPAP therapy is failing. Most users find that their comfort improves after making a few adjustments and giving themselves time to adapt. Consistent use, proper equipment maintenance, and regular follow-up with a sleep specialist can help ensure successful long-term therapy.
