How to take doxycycline capsules

You should take 1 doxycycline 100mg capsule at the same time each day.

  1. Start 1 or 2 days before you travel to a malarial area
  2. Keep taking them during your stay in the malarial area
  3. Continue for 28 days after you have left the malarial area

You can prevent doxycycline from giving you an upset stomach by:

  • swallowing your doxycycline capsule whole with a full glass of water
  • staying upright and not lying down for 30 minutes after you take your doxycycline
  • not taking doxycycline before going to bed
  • having food beforehand
  • taking a probiotic if you plan on taking doxycycline for a long time

For a short stay of a few days in a malarial area, you might prefer to take atovaquone and proguanil rather than doxycycline.

What to do if you forget to take your doxycycline

If you forget to take your doxycycline capsule, take it as soon as you remember. You should not double up or take more than 1 capsule of doxycycline to make up for it. Take your next doxycycline capsule at the planned time.

What to do after you finish taking your doxycycline

When you finish taking your doxycycline, watch out for any fever you might get within the next 12 months. If you do get a fever, check with a doctor to be sure that you do not have malaria.
