Pregnancy & Lactation
Pregnancy
There are no well-controlled studies on pregnant women
Animal data
- Reproduction studies performed in rats and rabbits at doses up to 34 times human dose revealed no evidence of impaired fertility or harm to fetus due to this drug
- Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed
Lactation
Not known whether this drug is excreted in human milk; because many drugs are excreted in human milk, exercise caution when administered to a nursing woman
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

flavoxate oral
FLAVOXATE - ORAL
(flay-VOX-ate)
COMMON BRAND NAME(S): Urispas
USES: This medication is used to treat certain bladder/urinary tract symptoms. Flavoxate is a smooth-muscle relaxant. It works by relaxing the muscles in the bladder. Flavoxate helps to reduce leaking of urine, feelings of needing to urinate right away, frequent trips to the bathroom, and bladder pain. This medication does not treat the cause of your bladder symptoms (such as urinary tract/bladder/prostate infection or inflammation).
HOW TO USE: Take this medication by mouth as directed by your doctor, usually 3 to 4 times a day. Take with food if stomach upset occurs.The dosage is based on your medical condition and response to therapy. Your doctor may lower your dose after your symptoms have improved. The length of treatment depends on the cause of the problem.Do not increase your dose or take this medication more often without your doctor's approval. Your condition will not improve any faster, and the risk of side effects may be increased.Tell your doctor if your condition lasts or gets worse.
SIDE EFFECTS: Nausea, vomiting, dry mouth, headache, drowsiness, dizziness, blurred vision, and nervousness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute.To prevent constipation, eat dietary fiber, drink enough water, and exercise. You may also need to take a laxative. Ask your pharmacist which type of laxative is right for you.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: nausea/vomiting/constipation that doesn't go away, mental/mood changes (such as confusion), eye pain, chest pain, fast/pounding heartbeat, signs of infection (such as sore throat that doesn't go away, fever), difficult/painful urination.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: Before taking flavoxate, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: stomach/intestinal problems (such as blockage, bleeding, ileus, infection, acid-reflux disease, chronic constipation, ulcerative colitis), heart problems (such as fast/irregular heartbeat, heart failure), a certain eye condition (glaucoma), kidney problems, a certain muscle disease (myasthenia gravis), difficulty urinating (for example, due to enlarged prostate), overactive thyroid (hyperthyroidism).This drug may make you dizzy or drowsy or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).This medication can cause decreased sweating. To reduce the risk of a serious reaction to too much heat (heatstroke), avoid becoming overheated in hot weather, saunas, or during exercise or other strenuous activities.Older adults may be more sensitive to the side effects of this drug, especially dizziness (more likely when standing up), drowsiness, constipation, trouble urinating, or confusion. Dizziness, drowsiness, and confusion can increase the risk of falling.During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.It is unknown if this drug passes into breast milk. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Some products that may interact with this drug are: potassium tablets/capsules, pramlintide.Tell your doctor or pharmacist if you are taking other products that cause drowsiness such as opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), or antihistamines (such as cetirizine, diphenhydramine).Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.
OVERDOSE: If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center. Symptoms of overdose may include: slow/shallow breathing, hallucination, seizures, loss of consciousness.
NOTES: Do not share this medication with others.This medication has been prescribed for your current condition only. Do not use it later for another condition unless told to do so by your doctor. A different medication may be necessary in that case.This medication may relieve the symptoms of a bladder infection, urinary tract infection (UTI), or prostate infection. However, it does not treat an infection. An antibiotic may be needed if you have an infection.
MISSED DOSE: If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose. Take your next dose at the regular time. Do not double the dose to catch up.
