<s>[INST] On February 4th, I got my wisdom teeth pulled out and i was prescribed with 800mg of ibuprofen which i took every 6-8 hours for the pain and I took that for about 4-5 days I think. I was supposed to get my period on February 26, but I didn t. And I am not feeling any symptoms that I usually feel before my period. Is it possible that ibuprofen delayed my period? [/INST] Thanks for your query, I have gone through your query. As far as the ibuprofen is concerned regarding the delayed periods, there are no effects on the periods. But the dose what you have taken is high, usually it is administered at a dose of 400 mg 3 times daily. The adverse effects can cause gastritis and stomach pain but not delayed periods. So consult a gynecologist and take an opinion. I hope my answer will help you, take care. </s>
