When and How to Take Hydroxychloroquine

Some general considerations include the following:
  • Hydroxychloroquine comes in tablet form. It is taken once a week to prevent malaria, starting two weeks before anticipated exposure and continuing until four to eight weeks after you return from the high-risk area. For other uses, it is usually taken once or twice a day.
  • It is best to take hydroxychloroquine with food or a glass of milk in order to prevent stomach upset.
  • Using this medication for malaria prevention in children creates unique problems, since it is available only in adult-strength tablets and since the drug is extremely bitter. However, your healthcare provider and pharmacist can work together to create a solution to these problems for your child.
  • For the medication to work properly, it must be taken as prescribed. Hydroxychloroquine will not work adequately if you stop taking it too soon.

Dosing Information

The dose of hydroxychloroquine that your healthcare provider recommends will vary depending on a number of factors, including:
  • The medical condition being treated (or prevented)
  • Your age and weight
  • Other medical conditions you may have
  • Other medications you may currently be taking.
As is the case with any medication, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
