What are the side effects of Detrusitol?
Detrusitol is a prescription medication used to treat an overactive bladder. It works by relaxing the bladder muscles, helping to reduce frequent urges to urinate and episodes of urinary incontinence. While it is an effective treatment, like all medications, Detrusitol may cause side effects. Understanding these potential side effects can help you manage your treatment effectively.
Key Takeaways
Detrusitol helps with bladder problems but can have side effects.
It relaxes the bladder to reduce frequent urination, but some people may experience dry mouth, dizziness, headaches, or constipation.
Serious side effects are rare but need medical help.
If you have severe stomach pain, blood in your urine, or trouble passing urine, you should see a doctor straight away.
Always follow your doctor’s instructions.
Take the right dose, don’t double-dose if you forget, and let your doctor know if you take other medicines to avoid harmful reactions.
Common Side Effects of Detrusitol
Some people may experience common side effects when taking Detrusitol. These symptoms are usually mild and may improve as your body adjusts to the medication. Below are some of the most reported side effects and how to manage them:

Who Can Take Detrusitol?

Can Elderly People Take Detrusitol?
Elderly individuals can safely take Detrusitol if prescribed by a doctor. It is a common treatment for incontinence and bladder issues in older adults.

If you have a known allergy to Detrusitol or its ingredients, you should not take this medication. Inform your doctor of any previous allergic reactions to medications.

Detrusitol may interact with other medications, affecting its effectiveness or increasing the risk of side effects. Inform your doctor if you are taking any of the following:

Antifungal medications (e.g., ketoconazole, itraconazole)

Swallow the tablet whole with water—do not chew or crush it.
If you miss a dose, take it as soon as you remember unless it is close to your next scheduled dose. Never double-dose.
Store Detrusitol in a cool, dry place, away from direct sunlight and moisture.
