Solid is intended for adults age 18 and older with perceived mild to moderate hearing loss. Do not use OTC hearing aids if you are under 18.
You should also seek professional care instead of self-treating if you have warning signs such as sudden hearing changes, drainage, pain, severe dizziness, hearing in only one ear, or certain ear conditions.
