Brief Answer:
use regesterone for 7 days

Detailed Answer:
Hello and welcome to HCM,

Congratulations for your marriage.

However it is already 11th today. So you will not be able to have a period before these dates. The only option is to take drugs and delay the periods. I will need to know the date of your last period to help you better.

The reason for prescription of pyricontin is unclear as it is not used to delay periods. However you may use regestrone 5mg twice daily upto 7 days to delay the period [ please give me the date of your last period if possible as this may not work sometimes]. Periods will come 7 days after stopping the drugs.

Hope this satisfies your query.
Thanks for using HCM.

Brief Answer:
period comes within 7 days sometimes even later

Detailed Answer:
Hello and welcome,

Stress usually delays periods. Pyricontin is not known to lower the side effects as there is no lietrature to show this. It is vitamin B6 only. You may take it as it helps the liver.

You can start the tablet from 12-13 and take it till 18 th or 19th as if a period comes before this it will most likely get over before the date of marriage. Periods usually start in the next 7 days after stopping the drug. It may range from 1 day [ very rare as commonly begins on day 3-4] to day 7 on any day.

Also regestrone may cause vomiting in a few, if you have vomiting then decease the dose to one tablet a day.

Hope this helps.

I am here for any more queries. Please do not get stressed. The drug will help you.

hi, thanks for the prompt response.

previously, some years back i have used some tablet to postpone my periods, not sure about the name of the tablet, then i have suffered with severe stomach ache.

Is there a chance of getting stomach ache this time also?
if so, please suggest few ideas to minimize the same , may be in terms of food and drinks.

Brief Answer:
yes it can cause abdominal pain

Detailed Answer:
Hello and welcome,

Yes these tablets may cause stomach ache in a few women. If you have had this issue take just one tablet at night after meals. Also take cold milk and gelusil or ranitidine 150 mg twice daily along with this to avoid gastric irritation.

However a single tablet may not be enough to delay periods and so we use them twice a day. If you are able to tolerate it then take it twice a day.
It may also cause nausea that can be minimised with drugs like ondenstrone 4 mg once daily.

Hope this helps.
