Peptides for sexual health, explained simply

The short answer

Some men cannot get or keep an erection firm enough to have sex. Some women have low sexual desire that causes distress.[7–8] 3 of the 6 we list are FDA-approved for erectile dysfunction in men or one type of low sex drive in women before menopause: Bremelanotide, Sildenafil and Tadalafil. Of the 6 options people try for sexual health, 2 are in the Melanocortins group and 2 are in the Heart and blood vessels group.

Warnings on the label

From the Viagra prescribing information (FDA label):[2]

  • not for men whose heart health makes sexual activity unsafe
  • an erection that lasts too long, or a painful one (priapism), needs emergency care
  • stop it and get medical help for sudden vision loss in one or both eyes, which may be a sign of a rare optic nerve problem (NAION)
  • stop it and get prompt medical help for a sudden drop in or loss of hearing
  • low blood pressure when taken with alpha-blockers or other blood pressure medicines
  • ritonavir (a protease inhibitor) greatly raises the amount of this drug in the blood, which can cause low blood pressure, fainting and long-lasting erections
  • combining it with other drugs of the same type (including sildenafil for pulmonary arterial hypertension) or other erectile dysfunction treatments has not been studied and is not recommended; it may lower blood pressure further
  • bleeding events have been reported, without a proven link; its safety in people with bleeding disorders or active stomach ulcers is unknown
  • it does not protect against sexually transmitted infections, including HIV

From the Cialis prescribing information (FDA label):[3]

  • not for men whose heart health makes sexual activity unsafe
  • the daily form keeps the drug in the blood all the time, which matters for interactions with other medicines (such as nitrates, alpha-blockers and blood pressure medicines) and with heavy drinking
  • an erection that lasts too long, or a painful one (priapism), needs emergency care
  • stop it and get medical help for sudden vision loss in one or both eyes, which may be a sign of a rare optic nerve problem (NAION)
  • stop it and get prompt medical help for a sudden drop in or loss of hearing
  • it can add to the blood-pressure-lowering effect of alpha-blockers and other blood pressure medicines
  • people with reduced kidney function may need dose limits, and the daily form is not recommended for severe kidney problems
  • people with liver problems need dose limits or caution, and it is not recommended for severe liver problems
  • heavy drinking with it makes a faster heartbeat, a drop in blood pressure on standing, dizziness and headache more likely
  • some medicines, such as ritonavir, ketoconazole and itraconazole, raise its level, so dose limits apply
  • do not take it with other drugs of the same type, including Adcirca; combinations with other erectile dysfunction treatments have not been studied
  • it has not been given to people with bleeding disorders or significant active stomach ulcers, so their use needs caution
  • it does not protect against sexually transmitted infections, including HIV
  • before it is used for an enlarged prostate (BPH), other urinary conditions with similar symptoms should be considered, and prostate cancer can occur alongside BPH

From the Vyleesi prescribing information (FDA label):[4]

  • a short rise in blood pressure and drop in heart rate after each dose; not for people with uncontrolled high blood pressure or known heart or blood vessel disease, and not recommended for people at high risk of heart or blood vessel disease
  • dark patches, including on the face, gums and breasts, which were not confirmed to clear in everyone after stopping
  • nausea, the most common side effect, which sometimes needed anti-nausea medicine or led people to stop

The research

What this doesn’t establish

Nothing on this page shows that any option helps sexual function in a way FDA has not approved.

A status shows where something stands with FDA, not whether it works or is safe for you. Being listed here isn’t a recommendation.
