Why is Microdox rx prescribed?

Doxycycline is a broad-spectrum tetracycline antibiotic used against a wide variety of bacterial infections, including Rocky Mountain spotted fever and other fevers caused by ticks, fleas, and lice; urinary tract infections; trachoma (chronic infections of the eye); and some gonococcal infections in adults. It is an approved treatment for inhalational anthrax. It is also used with other medications to treat severe acne and amoebic dysentery (diarrhea caused by severe parasitic infection of the intestines).

Doxycycline may also be taken for the prevention of malaria on foreign trips of less than 4 months' duration.

Occasionally doctors prescribe doxycycline to treat early Lyme disease and to prevent "traveler's diarrhea." These are not yet officially approved uses for Microdox rx.
Most important fact about Microdox rx (Doxycycline, Adoxa, Doryx, Doxy, DoxyCaps, Periostat, Vibra-Tabs, Vibramycin)

Generally, children under 8 years old and women in the last half of pregnancy should not take Microdox rx. It may cause developing teeth to become permanently discolored. (However, children under 8 may be given Microdox rx for inhalational anthrax.)
How should you take Doxy,Microdox rx (Doxycycline, Adoxa, Doryx, Doxy, DoxyCaps, Periostat, Vibra-Tabs, Vibramycin) without prescriptions

Take doxycycline with a full glass of water or other liquid to avoid irritating your throat or stomach. Doxycycline can be taken with or without food. However, if the medicine does upset your stomach, you may wish to take it with a glass of milk or after you have eaten.

Doxycycline tablets should be swallowed whole. If you have difficulty swallowing pills, you can take Microdox rx by opening the capsule and sprinkling the entire contents onto a spoonful of cool, soft applesauce. Be careful not to spill any of the contents. If you do, you will not be able to use this dose and will have to start over with a new mixture. Swallow the mixture immediately, without chewing, followed by a cool 8-ounce glass of water. Discard the mixture if you are not able to use it immediately; do not store it to use later.

Your doctor will only prescribe doxycycline to treat a bacterial infection; it will not cure a viral infection, such as the common cold. It's important to take the full dosage schedule of doxycycline, even if you're feeling better in a few days. Not completing the full dosage schedule may decrease the drug's effectiveness and increase the chances that the bacteria may become resistant to doxycycline and similar antibiotics.

If you are taking an oral suspension form of doxycycline, shake the bottle well before using. Do not use outdated doxycycline.

If you miss a dose...

Take the forgotten dose as soon as you remember. If it is almost time for the next dose, put it off for several hours after taking the missed dose. Specifically, if you are taking one dose a day, take the next one 10 to 12 hours after the missed dose. If you are taking two doses a day, take the next one 5 to 6 hours after the missed dose. If you are taking three doses a day, take the next one 2 to 4 hours after the missed dose. Then return to your regular schedule.

Storage instructions...

Doxycycline can be stored at room temperature. Protect from light and excessive heat.
