You should not take this antibiotic if you are allergic to Doryx or related medications.

You should talk to your healthcare provider prior to taking Doryx® (doxycycline hyclate delayed release) if you have:
  • Kidney disease, such as kidney failure (renal failure)
  • Frequent yeast infections
  • Liver disease or liver failure
  • Any other allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:

Specific Doryx Precautions and Warnings

Precautions and warnings to be aware of prior to taking this drug include the following:
  • To avoid damage to the esophagus while taking Doryx, make sure to take the medication with plenty of fluids. Do not take this medication lying down, and do not lie down immediately after taking your dose. These measures are necessary to make sure that the Doryx tablet does not accidentally stick in your throat, where it could cause significant irritation and damage.
  • Taking Doryx during pregnancy or before the age of 8 may cause the permanent discoloration of teeth in the infant or child.
  • Doryx is considered a pregnancy Category D medicine. This means that there is significant risk to an unborn baby. If you are pregnant, discuss these risks with your healthcare provider before using Doryx (see Doxycycline and Pregnancy for more information). In some rare situations, it may be appropriate for a pregnant woman to take this medication.
  • Many antibiotics have been known to cause pseudomembranous colitis (severe diarrhea). This is a serious condition that may potentially be fatal. If you experience severe, bloody, or prolonged diarrhea, contact your healthcare provider immediately.
  • Doryx can interact with certain medications (see Doryx Drug Interactions).
  • If you have kidney disease or severe liver disease, your healthcare provider may choose to give you a lower dose than normal or not prescribe Doryx at all.
  • If you are breastfeeding, it is known that Doryx passes through breast milk. Therefore, if you are breastfeeding, be sure to check with your healthcare provider before taking Doryx (see Doxycycline and Breastfeeding).
  • While taking antibiotics such as Doryx, other infections (such as vaginal yeast infections) have been known to occur. If you notice symptoms unrelated to your original condition, talk to your healthcare provider.
  • Antibiotics have been known to cause increased pressure in the skull. This usually stops when the antibiotic is discontinued. Make sure to talk to your healthcare provider if you experience any of the following symptoms while taking Doryx:


    • Headaches
    • Blurred vision
    • Nausea
    • Vomiting
    • Dizziness.


  • Skin reactions that resemble serious sunburns may occur if you are exposed to sunlight while taking Doryx. Try to avoid unnecessary sunlight exposure while taking this antibiotic. If sunlight exposure is unavoidable, cover as much of your skin as possible (long sleeves, long pants, or a hat), and use a sunscreen with a rating of SPF 45 or higher.
