- Allegra, Claritin, and other allergy meds. Certain antihistamines, both over the counter and prescription, can lead to vaginal dryness. If you use these drugs, you may need to supplement your sex with lubricants.
- Antidepressants. SSRI drugs like Prozac, Paxil, and Zoloft can prompt orgasmic dysfunction in women and lessen desire for sex. If you experience this side effect, talk to your doctor about adjusting your dosage. Since depression can also interfere with sex drive, you don't want your meds working against you!
- Antianxiety drugs such as Xanax. Like antidepressants, too much of these medications could decrease sex drive and delay orgasms.
- Hormonal birth control. In addition to other side effects, birth control pills and Depo Provera can decrease a woman's sexual desire and arousal. If this happens to you, consider switching to a nonhormonal birth control method.
