While adverse reactions to dicyclomine are uncommon, some patients who take the drug may experience mild side effects, including dizziness, dry mouth, blurry vision, nausea, drowsiness, physical tiredness, and nervousness. Tell your doctor if any of these are severe or do not go away.
Rare, more serious adverse reactions have also been known to occur. Get immediate medical attention if you have any confusion, forgetfulness, hallucinations, excessive tiredness, inappropriate mood swings, or symptoms of an allergic reaction (such as rash; hives; swelling of the face, mouth, or tongue; or difficulty breathing or swallowing).
Talk to your doctor about your medical history and inform them of all known allergies, plus all medications and supplements that you take. Tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding.
This is not a complete list of side effects or precautions. For more information please visit the National Institutes of Health’s DailyMed webpage for dicyclomine.
