Hyperhidrosis may look like “just a sweating problem,” but if you struggle with chronic sweating, you know it’s a life-altering medical issue. Basic treatments don't work, and you may need to explore prescription medications. Before you talk to your doctor about medication, educate yourself on the side effects of hyperhidrosis drugs.

Side Effects of Hyperhidrosis Drugs

The most common drugs used to treat hyperhidrosis are anticholinergics and beta blockers.

So what are they and how will they help you? In this post, we’ll go over the types of hyperhidrosis drugs and their side effects.

Anticholinergics

Anticholinergics stop sweat by blocking the neurotransmitter acetylcholine. Acetylcholine tells the body to sweat and perform other involuntary functions.

Common anticholinergics used to treat hyperhidrosis include glycopyrrolate, benztropine and oxybutynin. Let’s take a closer look at each.

Drug Description Side Effects
Glycopyrrolate Traditionally used to reduce excessive drooling, but it’s anticholinergic properties make it a viable hyperhidrosis medication. Dizziness, blurred vision, dry mouth, stuffy nose and constipation.
Benztropine Parkinson’s Disease medication that just so happens to decrease sweating and other involuntary body functions. Commonly prescribed to hyperhidrosis patients. Same as above plus drowsiness and nausea.
Oxybutynin Normally used to treat over activity of the bladder, but also stops sweat. Dry mouth, belching, diarrhea, heartburn, indigestion and irregular heartbeat.

The most serious side effect of anticholinergics is overheating.

Because sweat is necessary for regulating body temperature, patients could experience fainting or fever if they can't sufficiently sweat.

Beta Blockers

Beta blockers attack another source of sweat: anxiety. If you sweat profusely in tense situations, these medications may work best for you.

Here's an in-depth look at the most common beta blocker for hyperhidrosis, propranolol.

Drug Description Side Effects
Propranolol Treats high blood pressure, controls heart rhythm and other things that can trigger your body’s sweat response. Common side effects include a slower heart rate, hair loss, nausea, and tiredness. More serious side effects include hallucinations, sudden weight gain, and breathing problems.

Both beta blockers and anticholinergics can be effective if used correctly, but sometimes the side effects aren’t worth the risk.
