Question 8

Is Qualaquin safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Qualaquin is typically used during pregnancy only when a healthcare provider determines that the potential benefit to the patient outweighs the potential risk to the fetus. Malaria is a life-threatening condition that can cause severe complications for both the pregnant person and the fetus, making effective treatment necessary. However, there are concerns regarding the use of quinine during pregnancy.

High doses of quinine have been associated with adverse outcomes, including congenital malformations and fetal death. While these risks are primarily linked to doses much higher than those used for malaria treatment, the safety of therapeutic doses is not fully established. If you are pregnant or planning to become pregnant, it is essential to discuss the risks and benefits of this medication with your doctor.

Breastfeeding

Quinine, the active ingredient in Qualaquin, is excreted into human breast milk in small amounts. While these levels are generally low, the effects on a nursing infant are not fully understood. Healthcare providers advise caution when prescribing Qualaquin to individuals who are breastfeeding. It is important to consult with a medical professional to weigh the necessity of the medication for the mother against the potential risks to the nursing child.
