My HormonologyIf you take over-the-counter medications, vitamins, supplements, herbs or prescription drugs for menstrual-related issues or any other reason, here’s a gentle reminder: Most can interact with other medications, vitamins, herbs, supplements or even food and can have unexpected side effects. Just a few surprising ones you may not have known:

* Ibuprofen (for instance, found in Advil and Motrin), can make you more sensitive to the sun’s UV rays, which can result in a sunburn. So, wear protective clothing and apply a sunscreen with SPF 30 or above if you plan to be out in the sun while taking it.

* Garlic supplements may reduce the effectiveness of hormone birth control by speeding up the breakdown of the synthetic estrogen in the contraceptive. So, either use a back-up birth control method while taking garlic supplements or switch to a garlic-free supplement.

* Amoxicillin (a common antibiotic) can temporarily stain your teeth, so you may need to brush your teeth more frequently while taking it.
