Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088. Many of my patients, colleagues, friends, and even neighbors have asked me about the new drug flibanserin (brand name Addyi). Just this past Tuesday, the FDA approved this drug for treatment of low sexual desire in women. Flibanserin has generated more questions, comments, and media inquiries for me than I’ve ever experienced in my 20-year career as an Ob/Gyn.
While there are several medications that improve sexual function in men (including Viagra, the most famous one), flibanserin is the first drug ever approved by the FDA to improve sexual function in women. Here are what I consider the relevant facts and data about flibanserin, and the advice I give my patients. First of all, it’s not a “pink Viagra.” Viagra (sildenafil) treats erectile dysfunction in men by improving blood flow to the penis by inhibiting the enzyme nitric oxide synthase. In contrast, flibanserin is thought to work by increasing the release of the neurotransmitter hormones dopamine and norepinephrine, while decreasing serotonin release in the area of the brain that regulates sexuality. Viagra is taken just before having sex, while flibanserin needs to be taken daily. that the side effects were more pronounced when flibanserin was taken with alcohol. Controversy arose because only two of the 25 volunteers for the alcohol study were women.
To add to the controversy, an advocacy group who wanted flibanserin approved, called
If you take too much sildenafil or take it together with these medicines, the chance for side effects will be higher. It is important to tell your doctor about any heart problems you have now or may have had in the past. This medicine can cause serious side effects in patients with heart problems. If you experience a prolonged or painful erection for 4 hours or more, contact your doctor immediately. This condition may require prompt sildenafil 100 mg tab medical treatment to prevent serious and permanent damage to your penis.
If you experience a sudden loss of vision in one or both eyes, contact your doctor immediately. Check with your doctor right away if you have a sudden decrease in hearing or loss of hearing, which may be accompanied by dizziness and ringing in the ears. If you already use medicine for high blood pressure (hypertension), sildenafil could make your blood pressure go too low. Call your doctor right away if you have blurred vision, confusion, dizziness, faintness, or lightheadedness when getting up from a lying or sitting position suddenly, sweating, or unusual tiredness or weakness. This medicine does not protect you against sexually transmitted diseases (including HIV or AIDS). “Even the Score,” suggested there was gender bias in the FDA review process.
One big worry many people have, myself included, is the potential for flibanserin to be used off-label,
Common medication culprits are birth control pills, blood pressure pills, and antidepressants. If all of those seem to be okay, I then check on her stress level and her schedule. Often, I find that couples who are struggling with sexuality have not set aside any time and energy for their relationship. I ask, “If you and your partner were alone on a tropical island, and you had no worries or schedules, would you be interested in sex?” If the answer is yes, we work on strategies for prioritizing and carving out time for the relationship. If the answer is no, then I am left with the diagnosis of hypoactive sexual desire disorder (also known as HSDD).
I often try to send these couples to sex therapists, but these experts are few and far between, and are often expensive. In addition, many couples are too embarrassed to follow through. This subgroup of women with hypoactive sexual desire has been vexing to me because I have largely not been able to help them. They are typically in healthy relationships, and yet they have no desire, sex drive, or response to sexuality. I try to explore all options with these women; however, to date, there has not been a medical option. meaning that it could be used in a broader population of women for whom it wasn’t approved.
However the dose is usually not more than 40 mg 3 times a day. Children 1 year of age and older weighing 20 to 45 kg—20 mg 3 times a day. Children 1 year of age and older weighing 20 kg or less—10 mg 3 times a day. Children younger than 1 year of age—Use and dose must be determined by your doctor. For oral dosage forms (suspension or tablets): If you miss a dose of this medicine, take it as soon as possible.
However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep out of the reach of children. Do not keep outdated medicine or medicine no longer needed. Ask your healthcare professional how you should dispose of any medicine you do not use. For example, this population could include older women, those with medical
Flibanserin is only approved for pre-menopausal women. It has been shown to slightly improve sexual satisfaction in some women (some more than others). The potential side effects include low blood pressure, nausea, and fainting. Women should not drink alcohol sildenafil oral jelly 100mg or use birth control pills while taking it because they can worsen the side effects. Of course, some women may decide these requirements and side effects are just not worth it, since they can be pretty big drawbacks for a drug designed to improve the sex lives of premenopausal women.
In my practice, women of all ages have questions and concerns about sex and sexuality. Most women seeing an Ob/Gyn do. These questions often come up right after a woman has a baby, during perimenopause, and later in life as well. Women’s sexuality is very complex, and is affected by brain chemistry, mood, relationships, medications, and health status (of both partners). As a physician, if a woman comes to me reporting concerns with sexuality, I start by assessing her physical and mental health (depression is a common cause of loss of interest in sex), and then check to see if she is on medications that can affect interest in sex. issues, and those combining its use with alcohol or birth control pills.
