how can this treatment of a single dose after sex prophylactically be effective? doesnt it take a number of days for the medication to reach an effective level in the system, or does it work by bypassing kidney filtration an ending up directly in the ureters, bladder, and urethra upon urination?
i have had good results prophylactically and at the first onset withi the topical application of small amounts of OTC cortisone cream and antibiotic ointment around and at the entrance to the urethra. any comments?
Hi,
For infections related to sexual activity, your doctor may recommend taking a single dose of antibiotic after sexual intercourse.
Most uncomplicated UTIs can be treated with oral antibiotics such as trimethoprim, cephalosporins, nitrofurantoin, or a fluoroquinolone (e.g., ciprofloxacin or levofloxacin). Trimethoprim is probably the most widely used antibiotic for UTIs and is usually taken for 7 days. It is often recommended that trimethoprim be taken at night to ensure maximal urinary concentrations and increase its effectiveness.
Drugs commonly recommended for simple urinary tract infections include:
Amoxicillin (Amoxil, Trimox)
Nitrofurantoin (Furadantin, Macrodantin)
Ciprofloxacin (Cipro)
Levofloxacin (Levaquin)
Sulfamethoxazole-trimethoprim (Bactrim)
As an at-home treatment, increased water-intake, frequent voiding, the avoidance of sugars and sugary foods, drinking unsweetened cranberry juice, taking cranberry supplements, as well as taking vitamin C with the last meal of the day can shorten the time duration of the infection. Avoid coffee, alcohol, and soft drinks containing citrus juices and caffeine until your infection has cleared.
Hope this helped. Let me know if you may need any more information.
