Reading through the list of modafinil side effects, you won’t find a word about its impact on sexual arousal and sexual function on the whole. Still, numerous user reviews and case reports claim that there is a certain interconnection between modafinil and sex drive.

The users share their positive and negative experience associated with the impact of modafinil on their sexual life.

Women claim that the drug increases the libido and makes them more sensitive to sexual stimulation. Men, on the contrary, say that modafinil kills their libido. Yet there are also individuals whose problems with premature ejaculation were gone due to this popular drug. So where’s the truth in all this? To tell the truth, modafinil works differently for different people. The reaction to the drug is highly individual, so you never know how modafinil will affect your libido and sexual performance until you try it.

Is Modafinil Safe?

  • Mild diarrhea;
  • Nausea;
  • Dizziness.

The safety of modafinil in terms of sexual health is not clear. A number of case reports claim that high doses of the drug (those exceeding 400 mg a day) may lead to hypersexuality. The problem of modafinil and sex addiction was described in a case report about a 35-year old man suffering from the bipolar affective disorder. He got modafinil addicted and increased his daily dose to 1000 mg daily. The problem he came to the doctors with was the loss of control over his growing sexual desire and physical signs of sexual arousal.

To prevent such problems, modafinil users should stick to 200 mg dose or, if needed, reduce it to 100 mg or 50 mg a day.

How Does Modafinil Affect Your Sex Life?

There’s no scientific evidence as to the effects of modafinil on the sexual life of its users. However, anecdotal evidence claims that the effects on men and women are different. Modafinil and better sex is a story for women. A lot of female users of the drug say that the quality of sensations during sex, as well as their sexual arousal, have significantly improved due to modafinil tolerance.

On the other hand, men say that modafinil reduces their sex drive. Besides, some men need more time to get an erection when on modafinil. At the same time, they can last longer in bed, which is a benefit. This quality of the preparation is highly evaluated by men suffering from premature ejaculation. In some cases, the duration of sexual intercourse increased to 15 minutes, which is very long for men having this kind of intimate health problem.

How Does Modafinil Work?

Modafinil works by increasing the levels of norepinephrine, orexin, and histamine in the human brain. Besides, it inhibits dopamine reuptake thus increasing the levels of this chemical as well.

Histamine and orexin are the two neurotransmitters that are involved in the sleep-wake cycle regulation. The increase in their amounts in the brain helps people stay awake and alert. The effects of norepinephrine and dopamine are manifested via the improvement of the cognitive functions. It allows you to increase the workability and productivity without developing the feeling of tiredness even after long hours of work.

The on-label uses of the drug are associated mainly with its wakefulness-promoting effects, whereas those using it off-label love it for the way it increases their stress-resistance helping to stay focused and motivated.

Does Modafinil Decrease Sex Desires?

The impact of modafinil on sexual desire varies depending on the dosage of the medication taken. In most cases, the users say that modafinil, if taken in the recommended doses decreases libido in males. On the contrary, even 200 mg of modafinil a day stimulates sex drive in women.
