### input:
i have a cold right now and have taken phenylephrine hci chlorphenamine maleate paracetamol within the past 5 hours, can i still take norvette as an emergency contraception (4 pills within 150 hours from contact). I have never taken any kind of contraceptive before. I am also a smoker (average of 6 sticks a day) I would appreciate your advice. Thank you

### output:

Hello, and I hope I can help you today. I assume the pill you are mentioning is Corvette... which is a regular monthly cycle birth control pill.  You can use regular birth control pills as emergency contraception, but you must take 4 pills twice- 12 hours apart.  In short term dosing, this is not an issue with smoking nor will it be affected by any other medicines you are taking.  However, emergency contraception really is only effective within 72 hours of unprotected sex. However, you may develop nausea and vomiting as a side effect from all the estrogen in the pills.  Emergency contraception kits are available in pharmacies that have a different kind of hormone and fewer side effects.  Depending on where you are in the world, you do not necessarily need a doctors prescription.  These kits can work up to 5 days after intercourse (though most effective within 72 hours) so I recommend you use a store-bought kit rather than the Corvette. If you do use emergency contraception, it usually either delays your period or makes it come about 2-4 days after taking the medicine. So either way, if you miss your period, you should do a pregnancy test just in case. I hope I was able to answer your question and that my advice was helpful. Best wishes,
