Risks Associated with Phentermine
The risks associated with taking phentermine during pregnancy include potential developmental issues for the baby and complications for the mother.

Given these risks, healthcare providers recommend that individuals who are pregnant or trying to conceive should discontinue the medication as soon as they start planning for pregnancy.
Recommended Timeframe Before Conception
While there is no universally established timeframe for how long one should be off phentermine before attempting to conceive, the consensus is clear: discontinuation should occur as soon as pregnancy is planned. This allows the body to clear the medication and minimizes any potential risks to the developing fetus. It is advisable to consult with a healthcare provider for personalized guidance and to discuss any concerns regarding weight management during the preconception period.
