Treatments for PMDD vary according to the symptoms, and some therapies work better for some people than others. If treatment does not succeed at first, a person should not give up and keep working on a treatment plan with their doctor.
A doctor may suggest one or more of the following to help alleviate PMDD symptoms:

The main difference between PMDD and PMS is the severity and type of symptoms a person experiences. For example, someone with PMDD may experience more affective symptoms more often than someone who doesn’t have it. These symptoms include depressed mood or mood swings days before their period starts.
A person should talk to their doctor if they are experiencing PMDD or PMS symptoms that interfere with their daily lives. A doctor should be able to help distinguish between the two conditions and suggest a treatment plan.
Keeping a journal of symptoms can help a doctor reach a diagnosis, especially if the symptoms are severe and regular enough to indicate PMDD.
A person should also talk with their doctor if their symptoms worsen or treatment is no longer effective, as they can make adjustments to the treatment plan.

It may take a while for someone to find an effective treatment plan, so they must stay in touch with their doctor and provide updates on what works well and what does not.
