What Can Cause Hand Tremors?

Certain Medications

Patients who take certain medications are at an increased risk of experiencing hand tremors as a side effect. Inhaled asthma medications such as albuterol, salmeterol, and formoterol increase levels of stress hormones in the body, and this might result in tremors. Amiodarone, a drug used to treat heart rhythm irregularities, is known to cause hand tremors in at least one-third of the patients who take it. Selective serotonin reuptake inhibitors are associated with hand tremors in roughly twenty percent of patients who use them, and lithium and tricyclic antidepressants might also cause tremors. Hand tremors caused by medications differ from those caused by neurological conditions. The tremors that stem from medication occur with voluntary movements such as when reaching for something or when performing a specific task. Unlike other kinds of tremors, medication-induced tremors tend to affect both hands, and they don't get worse over time. Tremors caused by medication tend to resolve if the dose is lowered or if the medication is switched or discontinued.
