Zoloft and hyperthyroidism

Zoloft is the brand name for sertraline, an antidepressant. Hyperthyroidism can itself cause a racing heartbeat, tremor, sweating, bowel changes, anxious feelings and disturbed sleep. Some of these symptoms can also occur when starting sertraline or when its dose is changed, so it can be difficult to tell which factor is contributing.

An overactive thyroid can change how you feel emotionally and physically. Feeling more restless does not by itself show that either the thyroid condition or the medicine is worsening. A clinician can consider the timing of symptoms, your thyroid treatment and any recent blood-test results.

Tell the prescriber and thyroid-care clinician about every medicine, supplement and herbal product you use. Take Zoloft exactly as prescribed and do not stop it suddenly unless a clinician tells you to do so. Keep a brief note of when symptoms began, dose changes, sleep, bowel habit and pulse sensations; this gives the review a clearer starting point.

Arrange follow-up if symptoms are new, troublesome or changing. Thyroid treatment may require adjustment separately from mental-health treatment, so avoid changing either plan on your own.

Seek urgent medical assessment for chest pain, fainting, severe shortness of breath, a very fast or irregular heartbeat, marked confusion, or severe agitation. Get prompt support if you develop thoughts of harming yourself or feel unable to keep yourself safe. Persistent vomiting, diarrhoea or inability to drink can also need timely care because dehydration may add to dizziness and palpitations.

Ask whether your current symptoms fit thyroid activity, a Zoloft effect, anxiety, or another cause; when thyroid tests should be checked; and which symptoms should prompt a same-day call. Bring the names and doses of all medicines, including thyroid tablets and any over-the-counter products.
