Celexa and excessive sweating (or reduced sweating)
Changes in sweating — both excessive (hyperhidrosis) and reduced (hypohidrosis) — are common but underreported side effects of many medications. Celexa (Citalopram) at 10mg, 20mg, 40mg may shift sweating depending on how Citalopram affects autonomic and thermoregulatory pathways.
Why Celexa can change sweating
Sweating is regulated by the sympathetic nervous system, primarily through cholinergic signalling at sweat glands. Citalopram can affect this directly (cholinergic agonism or blockade) or indirectly through changes in body temperature setpoint, vasodilation or anxiety. Citalopram selectively inhibits the serotonin reuptake transporter, increasing synaptic serotonin availability with limited affinity for noradrenaline transporters or other receptors. Some medications increase night sweats specifically; others reduce sweating and increase heat-intolerance risk.
Practical guidance
Excessive sweating on Celexa at 10mg, 20mg, 40mg is rarely dangerous but can affect quality of life. Mild cases are managed with antiperspirants, lighter clothing and trigger avoidance. Reduced sweating is more concerning in hot weather because it impairs cooling — care with hot environments, hydration and avoiding strenuous heat exposure is the practical response. Persistent or severe cases warrant prescriber review.
Frequently asked questions
Can Celexa cause excessive sweating? ▾
For some users, yes — sweating changes on Celexa at 10mg, 20mg, 40mg are listed in the prescribing information for Citalopram when documented. Night sweats and exercise-related sweating are common patterns; persistent severe sweating warrants review.
Will reduced sweating on Celexa cause overheating? ▾
Reduced sweating impairs the body's natural cooling and can raise the risk of heat exhaustion in hot weather or strenuous exercise. People on medications that reduce sweating should be cautious with heat exposure, hydrate well and consider activity timing.
