Drugs and Medications to Treat Bladder Infections

Bladder Infections
Bladder infections are cured with a wide range of antibiotics. The appropriate antibiotic, its dose and the duration of the treatment depend upon the bacterium responsible for the infection and the severity of the infection. Uncomplicated infections are cured within three to seven days. Long-term treatment with antibiotics is sometimes recommended to prevent recurrent bladder infections.

Medications to Treat Bladder Infection


The pain, irritation, burning and discomfort caused by bladder infection can be treated with phenazopyridine. However, this medication cannot cure the infection. Before an antibiotic starts working, the analgesic effect of phenazopyradine provides fast relief from the symptoms of the infection. Phenazopyradine is taken orally up to thrice a day or as directed by the physician after meals. It is speedily excreted, providing fast relief from pain while urinating.



Once the antibiotic starts working and the symptoms of the infection subside, your physician may ask you to stop the medication. Stomach upset, headache and dizziness are common side effects of the drug. Change in color of urine is a harmless side effect of phenazopyridine.


Ciprofloxacin belongs to a class of antibiotics called fluoroquinolones. Extended release ciprofloxacin tablets are commonly used for treating bladder infection. These tablets are usually taken once a day or as directed by the physician. Ciprofloxacin should not be taken with milk, dairy or calcium fortified foods. Drowsiness, nervousness, anxiety and increase in heartbeat are common side effects of the antibiotic medication that can be minimized by limiting intake of foods and beverages containing caffeine such as coffee, tea, carbonated drinks and chocolate. Stomach pain, nausea, vomiting, diarrhea, heartburn, headache, vaginal itching and urgency to urinate are other side effects of the drug.


Amoxicillin belongs to the class medications called penicillin-like antibiotics. It is usually taken twice or thrice a day to heal the bladder infection.



Side effects that might occur following amoxicillin intake include vomiting, stomach upset and diarrhea. People allergic to penicillin may not tolerate amoxicillin.


Ampicillin can effectively treat bladder infection. This penicillin-like antibiotic can be taken orally up to four times a day or as directed by the physician. Ampicillin should be taken on empty stomach, at least two hours after or one hour before a meal. It may cause vomiting, diarrhea, stomach upset and rash.
