1. What is Ditropan and what is it used for

Ditropan belongs to a group of medicines called urinary antispasmodics.

This medicine works on the contractions of the bladder and delays the need to urinate. It can be used to treat some types of incontinence and other urinary problems.

Ditropan can be used in children aged 5 years and older to treat:

• involuntary loss of urine (urinary incontinence)
• increased need or urgency to urinate
• involuntary loss of urine at night, in combination with non-pharmacological treatment, when other treatments have not worked

2. What you need to know before you take Ditropan

Read the following sections carefully:

Do not take Ditropan

• if you are allergic to oxybutynin hydrochloride or any of the other ingredients of this medicine (listed in section 6).
• if you have any urinary tract disease with possible urinary retention.
• if you have gastrointestinal disorders of an obstructive type, intestinal atony (laxity) or paralytic ileus (functional intestinal obstruction).
• if you have toxic megacolon (abnormal constant dilation of the large intestine).
• if you have severe ulcerative colitis (a disease that causes chronic diarrhea).
• if you have myasthenia gravis (muscle weakness).
• if you have glaucoma (increased eye pressure) or a shallow anterior chamber of the eye.
• if you have increased urinary frequency and urinate more at night due to kidney or heart problems.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Ditropan.

Special care should be taken:

• if you have Parkinson's disease because you have a higher risk of adverse reactions to the product.
• if you have autonomic neuropathy (neurological disease).
• if you have any intestinal disease (including intestinal obstruction), liver or kidney problems.
• if you have clinically significant vesical obstruction, as it may worsen and cause urinary retention.
• if you have gastrointestinal disorders, as Ditropan may decrease gastrointestinal motility.
• if you have hiatal hernia/gastroesophageal reflux and/or are taking medications such as bisphosphonates, as they may cause or worsen esophagitis.
• if you have a urinary tract infection, as appropriate antibacterial treatment should be instituted.
• if you are taking other anticholinergic medications.
• because Ditropan may worsen cognitive disorders, symptoms of prostatic hyperplasia (enlargement of the prostate) and tachycardia (increased heart rate). Therefore, it should be used with caution in cases of hyperthyroidism (overactive thyroid gland), congestive heart failure, cardiac arrhythmia (heart rhythm disorders), coronary artery disease, and hypertension (high blood pressure).
• because Ditropan may produce anticholinergic effects on the nervous system, e.g., hallucinations, agitation, sleep disorders, confusion, blurred vision, and somnolence, and alcohol consumption may also increase somnolence.
• because Ditropan may cause angle-closure glaucoma. If you experience sudden loss of visual acuity or eye pain, contact a doctor immediately.
• because Ditropan may reduce saliva production, leading to the formation of dental caries, gum inflammation, or fungal infections in the mouth.
• if you are in a place with very high temperatures or have a fever, you may feel heat exhaustion due to decreased sweating caused by this medication.
