Blurred Vision
This symptom occurs because anticholinergics may affect the muscles responsible for controlling the shape or focus of the eye. This can make it difficult for an individual with an allergy to see clearly, causing their vision to become blurred.
Dry Mouth
Anticholinergics can cause decreased saliva production, leading to a feeling of dry mouth. This is characterized by a sticky, dry feeling in the mouth and throat, frequent thirst, sores in and around the mouth, cracked lips, and a dry red tongue.
Constipation
Anticholinergics can affect the muscles responsible for moving food and waste through the stomach and intestines, which can lead to constipation – a potential symptom of an allergy.
Confusion
Anticholinergic drugs can cross the blood-brain barrier and thus influence the central nervous system. Over time, this can lead to symptoms of confusion or memory loss, particularly in older adults>
Urinary Retention
This refers to the inability to empty the bladder completely. If you're allergic to anticholinergics, you may experience an uncomfortable feeling of fullness or difficulty passing urine.
Increased Heart Rate
Anticholinergics block the action of the neurotransmitter acetylcholine, which can affect the heart rate. An increased heart rate or palpitations may indicate an adverse reaction or allergy to the medicine.
