Combining arthritis drug with morning-after pill boosts effectiveness, study suggests

A study found taking levonorgestrel with piroxicam prevented 95% of pregnancies, compared to 63% with levonorgestrel alone.
Levonorgestrel's effectiveness drops from 95% to 58% or lower between 1-3 days after sex, but piroxicam may extend effectiveness.
Piroxicam requires a prescription in many countries and may have side effects, but other anti-inflammatories may work similarly.
Further research is needed to confirm findings in other populations beyond the Asian women studied.
The combination targets ovulation and implantation through different hormone mechanisms, enhancing contraceptive efficacy.
