Honest experience, no lie.
I have been taking Ciprofloxacin for almost a week now (five days) 500mg po bid (by mouth twice daily) along with an OTC 10 percent benzoyl peroxide (Clearasil Ultra Rapid Action Treatment Cream) product.I was already using the Clearasil before starting the treatment and it was only mildly effective at controlling my cystic acne.
Since the addition of the Ciprofloxacin treatment, there has been a noticeable change in the reduction of my cystic acne. I no longer see a whole lot of inflammation or redness in the affected areas and can safely assume that at this rate it won't be long (maybe a week or two more) before my moderate/severe acne is almost completely under control. I am very content with the results, although I must point out that I am a bit concerned about the possible effects that Cipro can have on your tendons (tendonitis) and possibly creating an antibiotic resistance. I did stop exercising to prevent any possible damage to a tendon, and will also complete the treatment for the entire duration, not simply stop midway and risk a possible return of the infection and creating an antibiotic resistance.
Also, I was originally prescribed Docycycline Hyclate, which may produce fewer side effects, but since I am a poor college student and don't have insurance (Doxycycline Hyclate is about $170 for a monthly 500mg po bid treatment, at Walmart Pharmacy) my doctor changed the prescription to Ciprofloxacin which qualifies for the $10 monthly prescription at most Walmart stores.
Weigh out the cost, the benefits and the side effects. If you can afford the Doxycycline Hyclate. I would suggest you go with that instead, which is just as effective and has fewer side effects) but if you don't have much money to spare, Ciprofloxacin is a good choice. Just take care of yourself. Don't work out so hard that you might hurt a tendon and please, complete the whole regimen to avoid creating antibiotic resistance with the infection coming back only stronger.
Hope this helps someone! Best wishes my friends.
