The question of whether discontinuing hormonal contraception (HC) can cause depression is a significant concern for many people and a recognized area of research. Hormones have a profound influence on the brain, and any major shift in hormone levels—whether starting or stopping a medication—can impact mental health. This connection is rooted in the complex biological interplay between synthetic hormones and the body’s neurochemical systems.
The Connection Between Hormones and Mood
The synthetic hormones found in birth control, which often include a progestin, function by suppressing the body’s natural reproductive cycle and stabilizing hormone levels. When this steady, external source of hormones is removed, the brain and body must rapidly adjust to the sudden withdrawal and the return of natural, cyclical hormone production. This transition can lead to a temporary state of neurochemical imbalance.
A key mechanism involves the interaction of synthetic hormones with neurosteroids, which are steroids produced in the brain that influence mood. One such neurosteroid is allopregnanolone, a metabolite of progesterone that acts on GABA-A receptors, enhancing the calming effect of the neurotransmitter GABA. The synthetic progestins in hormonal contraception can interfere with or suppress the body’s natural production of allopregnanolone.
When hormonal contraception is stopped, it takes time for the natural production of neurosteroids to fully resume and stabilize. This lag in the return of a natural calming agent can lead to symptoms of anxiety, irritability, and depressive mood. Furthermore, hormonal changes can indirectly affect the serotonin system, which regulates mood.
Identifying the Source of Mood Changes
Experiencing a dip in mood after stopping hormonal contraception is common, but it is important to accurately identify the source of the change, as there are three main possibilities. The first is a purely physiological adjustment, representing a short-term reaction as the body clears the synthetic hormones from its system. The second possibility is the return of a pre-existing condition that was masked by the birth control.
Hormonal contraception, by stabilizing hormone levels, can effectively manage or suppress symptoms of conditions like premenstrual dysphoric disorder (PMDD) or underlying anxiety. If a person’s mood changes are severe and cyclical, particularly in the week or two before their expected period, it may indicate that the underlying condition has resurfaced. A helpful question to ask is whether symptoms like severe mood swings or depression were present before starting the hormonal contraception. Finally, not all mood changes are biologically linked to the cessation of hormonal contraception, and they may be related to unrelated life stressors.
Timeline and When to Consult a Professional
The adjustment period after stopping hormonal contraception is typically a temporary phase as the body works to stabilize its natural endocrine cycle. For most people, the physical and emotional symptoms of adjustment, including mood changes, will begin to subside within one to three months. This timeframe is necessary for the body to reliably resume its own hormone production and establish a regular menstrual cycle.
While waiting for stabilization, certain self-care strategies can support the transition, such as maintaining good sleep hygiene, engaging in regular physical activity, and ensuring adequate nutritional support. However, it is important to recognize when symptoms cross the line from temporary adjustment to a more serious concern. If depressive symptoms, anxiety, or irritability persist beyond the three-month mark, professional consultation is warranted.
Immediate consultation is necessary if a person experiences thoughts of self-harm, suicidal ideation, or if the mood changes are so severe that they interfere with daily functioning, such as the ability to work, study, or maintain relationships. Seeking help is a proactive step, as a healthcare provider can evaluate the symptoms, rule out other causes, and discuss treatment options.
