Vibramycin Oral

Generic Name: DOXYCYCLINE - ORAL
Pronounced: (dox-ee-SYE-kleen)

Vibramycin Oral Side Effects

Stomach upset, mild diarrhea, nausea, headache, or vomiting may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these unlikely but serious side effects occur:

  • stomach pain
  • yellowing of the eyes/skin
  • vision changes
  • mental/mood changes


Doxycycline may make you more sensitive to sunlight (photosensitive) while you are taking it and for 1-2 days after you finish it. Avoid prolonged/direct sun exposure, tanning booths, and sunlamps during this time. Use sunscreen and wear protective clothing if you must be out in the sun. Symptoms of photosensitivity include sunburn that is much quicker/more severe than usual and tingling of the hands/feet/nose.

This medication may rarely cause a severe intestinal condition (pseudomembranous colitis) due to a type of resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have any of the following symptoms because these products may make them worse. Tell your doctor immediately if you develop:

  • persistent diarrhea
  • abdominal or stomach pain/cramping
  • blood/mucus in your stool


Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection (oral or vaginal fungal infection). Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.

A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include:

  • rash
  • itching/swelling (especially of the face/tongue/throat)
  • severe dizziness
  • trouble breathing


This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
