Obesity doesn’t preclude females from using the morning-after supplement however it’s crucial to notice it decreases its effectiveness. In these instances, females may want to have copper IUD inserted alternatively.

You can find medications that communicate using the morning-after tablet and possibly allow it to be less efficient: some anti-epilepsy medications, St John’s Wort and medications for tuberculosis and HIV. These medications increase the break down of the morning-after capsule in the human body.

It’s important to inform your pharmacists about other medications you’re taking just in case there clearly was a medication conversation. In these instances, your pharmacist may suggested you just take an increased dosage of Postinor.
