Hormone replacement therapy (HRT): This may help improve vaginal dryness and restore sexual comfort (thus, boosting libido) for women going through menopause. Testosterone therapy: This can be prescribed to treat low libido in women entering menopause and in the years that follow. Sometimes, sexual dysfunction isn’t about biology — it’s about everything else going on in your life that puts sex on the back burner. “Sexual health in women is about more than just blood flow,” Dr. Zanotti says.
“It’s about your mental health, your relationship, how comfortable you feel in your body and so much more.” Here are a few strategies that may help: If sex is painful, pelvic floor physical therapy may help. As you get older, vaginal tissue becomes drier and less elastic. Using lubricants or vaginal moisturizers, particularly after menopause, can help can make sex more pleasurable. Prioritize exercise, manage stress and sleep — they can all affect your sex drive more than you might think. Talk with a therapist, especially one who specializes in sexual health or trauma, if your low sex drive is related to things like mental health concerns, past sexual trauma or negative body image.
Have an open conversation with your healthcare provider. They can help you identify the cause and explore personalized solutions. Viagra might sound like a quick fix, but it rarely is.

Common side effects of Cialis and Viagra that are similar include flushing (redness or warmth of the face, neck, or chest), headaches, stomach pain or upset, flu-like symptoms (such as stuffy nose, sneezing, or sore throat), memory problems, muscle or back pain, blurred vision and changes in color vision (such as an inability to differentiate between the colors green and blue), dizziness, diarrhea, nausea, low blood pressure, abnormal ejaculation, and prolonged erections (priapism), loss of hearing, and ringing in the ears. One difference between the drugs is how long they stay in your system.
Cialis provides penile hardness (the ability to obtain an erection) over a longer period than Viagra because it lasts up to 18 hours, while Viagra only lasts for about 4 to 6. Cialis (tadalafil) and Viagra (sildenafil) are oral drugs that are used for treating impotence (the inability to attain or maintain a penile erection) and benign prostatic hyperplasia (BPH). They are in a class of drugs called phosphodiesterase-5 (PDE5) inhibitors that also includes vardenafil (Levitra, Staxyn ODT), and avanafil (Stendra). Penile erection is caused by the engorgement of the penis with blood. Under viagra connect form normal conditions, sexual stimulation leads to the production and release of nitric oxide in the penis.
Nitric oxide then activates the enzyme, guanylate cyclase, which causes the production of cyclic guanosine monophosphate (cGMP). It is the cGMP that is primarily responsible for the erection by affecting the amount of blood that the blood vessels deliver and remove from the penis. Cialis and Viagra inhibit an enzyme called phosphodiesterase-5 (PDE5) which destroys the cGMP. Thus, Cialis and Viagra prevent the destruction of cGMP and allows cGMP to accumulate and persist longer. The longer cGMP persists, the more prolonged the engorgement of the penis. Therefore, these drugs may increase the levels of tadalafil in the blood.
If these drugs are being used at the same time as tadalafil, the dose of tadalafil should be reduced to 10 mg every

(And who can argue with that as a perk?) But that’s not true for everyone. Some women taking Viagra may experience side effects like: If you have low blood pressure or you’re taking blood pressure medication, Viagra can cause a further drop that may lead to dizziness and even fainting. And mixing Viagra and alcohol is a big no-no because it can worsen the side effects, Dr. Zanotti warns. While Viagra might work on the physical side of things, other FDA-approved treatments can help women with other issues, like sexual desire.
“Viagra might help some women with the physical mechanics of sex, but it’s not going to help with other things that keep you from being ‘in the mood,’” Dr. Zanotti points out. No pill is going to make sure the laundry is done, the kids are asleep, or that you’re feeling confident in yourself and your relationship. But Dr. Zanotti notes a few medications that may help increase your interest in sex: Addyi® (flibanserin): A daily pill for premenopausal women with low sexual desire.
It affects brain chemicals tied to libido. Like Viagra, it can lower blood pressure and shouldn’t be taken with alcohol. Vyleesi® (bremelanotide): A self-injection that you use before sex. It’s approved only for premenopausal women whose low libido isn’t caused by another health condition. Wellbutrin® (bupropion): An antidepressant that may help improve libido, especially if your low sex drive is related to depression or SSRI use.
