Can being on antibiotic and pain killer for your teeth delay or make you miss your period? Help please?

Not likely. If you're not pregnant, you may miss your period due to stress, excessive exercise, antipsychotics and antidepressants medications. Antibiotic and painkillers are not effecting the period. Nevertheless, it’s always a good idea to make an appointment with your PCP when you notice anything out of the ordinary. .
Rarely. Antibiotics can interfere with birth control medications This was discovered years ago and is now a rare problem. Using the same pharmacist helps because they have a record of all your mends and will be alerted if there is a conflict. Also some antibiotics come with a warning label it it is known they interfere.
