Doryx

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 Do not use outdated doxycycline.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.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking doxycycline.

• Side effects may include:
  Angioedema (chest pain; swelling of face, around lips, tongue and throat, arms and legs; difficulty swallowing), bulging foreheads in infants, diarrhea, difficulty swallowing, discolored teeth in infants and children (more common during long-term use of tetracycline), inflammation of the tongue, loss of appetite, nausea, rash, rectal or genital itching, severe allergic reaction (hives, itching, and swelling), skin sensitivity to light, vomiting

Why should Doryx not be prescribed?

If you are sensitive to or have ever had an allergic reaction to doxycycline or drugs of this type, you should not take this medication. Make sure your doctor is aware of any drug reactions that you have experienced.
