It has been suggested that you take doxycycline because it is considered an important part of the treatment for many types of hair and scalp disorders including Lichen planopilaris and Follicultius decalvans.

What is doxycycline and how does it work?

This medication is currently prescribed off-label. This means that it is being used for a condition it was not first intended to treat.

Doxycycline has only been prescribed by the consultant after careful consideration of other treatment options.

Doxycycline is an antibiotic that is used in the treatment of hair conditions because of its anti-inflammatory effect. It has been proven helpful in reducing the redness, swelling and discomfort in many patients with Lichen planopilaris and Follicultius decalvans.

What is the dose of doxycycline?

Doxycycline is prescribed as 100mg capsules, taken either once or twice a day.

Please note that dairy products can reduce the amount of doxycycline that is absorbed and reduces the effect of the medicine. You should avoid dairy products for at least 3 hours before taking doxycycline.

Possible side effects of doxycycline

  • Doxycycline can cause photosensitivity. This is where the skin becomes oversensitive to sunlight. Therefore, it is recommended that while you are taking doxycycline sun exposure should be avoided wherever possible
  • Doxycycline can cause an upset stomach. If this happens, taking the medicine with food may be helpful
  • Headaches
  • Heartburn
  • Weight gain
  • Loss of appetite
  • Flushing
  • Skin rash
  • Candida (yeast infection affecting the mouth or genitalia)

Other side effects may be possible but many patients take doxycycline without any side effects.

If you develop any side effects while taking doxycycline, please contact Dr Takwale’s secretary.

Medications not to be taken with doxycycline

The effect of doxycycline will be reduced if taken with:

  • Antacid medication (medicine to help with reflux symptoms)
  • Iron, zinc or calcium supplements
  • Alcohol

Doxycycline may reduce the effects of some medications. If you have any concerns about this, please ask your pharmacist for advice.

Important points to remember

Doxycycline must not be used in pregnancy or when breastfeeding because there is no research to suggest it is safe to do so.

Please read the patient information leaflet enclosed with the medication.
