La doxycycline, membre de la famille des tétracyclines, agit par inhibition de la fixation de l’ARNt sur la sous-unité 30S du ribosome, empêchant l’élongation de la chaîne peptidique. Elle se caractérise par un spectre très large incluant bactéries atypiques, rickettsies, chlamydiae et spirochètes. Sa biodisponibilité digestive est excellente, mais elle est diminuée en cas d’ingestion simultanée de sels de calcium, fer ou magnésium. La doxycycline diffuse bien dans les tissus et possède une demi-vie longue, permettant des administrations biquotidiennes. Elle est éliminée principalement par voie biliaire. Les précautions concernent le risque de photosensibilisation, d’hyperpigmentation dentaire et de troubles digestifs. Dans les recommandations cliniques, la mention doxycycline sans ordonnance est souvent accompagnée de rappels sur la nécessité d’éviter son usage chez l’enfant et la femme enceinte, ainsi que sur la surveillance des traitements prolongés.

  • Amazon Customer - Freakish shot second time using it. 5 Stars.

    Second time I used this I had such a blast that it hurt a bit. Shot went over my girlfriend from behind. Never experienced anything like that before. I haven't finished it yet but I was so amazed I had to put this review up early. It was one of those you will never forget and may never duplicate but it was worth it. This is a legit unsolicted review and yes I actually paid for it with my own money.

  • D. Isaacs - A decent buy and trimmer!

    Works great! But wasn't sharp enough for the first time. But it start cutting good when I oil the blade properly. Let's see if it hold up for the next few months from now. I use it to cut my beard and side burns close to the skin then I use a Phillips Norelco Rota to give me a smoother finish. It can use to line give you a decent line up of your hair line and beard and side burns. It won't give you the closest shave but can aid with another trimmer.

  • Linda J. Shull - Worth every penny!

    These work as well as the more expensive brands and last for years. I got these for a second mt. bike because of the quality of the ones, still in use, I purchased 5 years ago. Easy to clean, tough as hell, and cheap! They've outlasted 3 chains, a cassette, and several disc brake pads

  • R. J - Not so effective!

    This product, like many products out there is just another product to make companies money. I have many acne scars on my face ever since I began developing acne about three years ago. I was hoping to see effective results when using this product, but I feel like if you don't start seeing a difference within a week, no matter how small or big the difference is, then you're just wasting my time and money. If they expect me to keeping buying this product in the hopes that the prolonged use will eventually pay off, then I simply do not have the patience to continue on with such a product. I know of more effective and cheaper ways of dealing with acne scars. This product is just false promises, in my opinion.
