<s>[INST] I was prescribed the Cilest Contraceptive pill about 5 weeks ago, the first cycle was fine, but now that i have started my second pack I am experiencing what I think are heart palpation roughly every 10minutes. Is this becuase of the tablet? Should I stop taking it? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Yes, hormonal pills can have side effects of palpitations. Actually these pills can cause stress and anxiety and these can cause tachycardia, palpitations etc. Not all women tolerate hormone pills. So in my opinion, you should stop hormonal contraceptive pills because they are causing side effects in you. Better to use barrier contraceptive like female condom or male condom. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
