THESE COULD AFFECT YOU
Some antihistamines dry up the sinuses, so in theory, they could dry out the vagina, too. However, according to experts, the antihistamines that you take for sinus problems affect mucus secretions in the nose. They have no direct link to sexuality. They can cause drowsiness – which could then affect your arousal levels.
Birth Control Pills
Some studies show that birth control pills can decrease testosterone levels in women – which could in turn, lead to a lower sex drive. Many birth control pills are oestrogen-based. Long-term use curbs testosterone levels in women and increases the production of a sex hormone-binding compound, which further inhibits sex drive.
