Anticholinergics are drugs that function by blocking the neurotransmitter acetylcholine in the brain. They are derived from plants in the nightshade family, which are typically deadly. Specifically, they work by keeping acetylcholine from binding to its receptor in nerve cells. The nerves in the system affected (part of the automatic nerve system) are responsible for impulses while the body is at rest as well as the involuntary movements muscles in the gastrointestinal tract, lungs, urinary tract, and other parts of the body. They also can help balance the body’s production of dopamine and acetylcholine, and are used to treat a variety of different ailments.

Signs of an overdose are generally particularly (and/or dangerously) severe iterations of the various side effects. Possible side effects include:
- Dry mouth
- Blurred vision
- Difficulty urinating
- Memory Problems
These drugs should not be prescribed for anyone with myasthenia gravis, liver disease, hypertension, heart failure, hiatal hernia, Down’s syndrome, hyperthyroidism, urinary tract blockage, enlarged prostate, glaucoma, tachycardia, or severe constipation. Side effects are often significantly more severe in elderly patients, and doctors usually only prescribe these medications to younger patients. They should not be taken with alcohol. They can also cause a decrease in sweating that can increase body temperature and make exercise dangerous if proper precautions aren’t taken. You should consult with your doctor before beginning these medications, and they should not be taken if you’ve ever had an allergic reaction to any drugs in this class.
