    Trouble staying hard: treatments, supplement limits and when to seek care

    Persistent difficulty maintaining an erection is a reason for medical assessment, not just a stronger supplement. Depending on the cause, treatment can include a prescription medicine, a vacuum device, counselling or changes to an existing medicine. The safest choice depends on health conditions and other drugs.

    Treatment starts with a cause and medicine review

    NIDDK describes reviewing medicines, health factors and psychological contributors. Do not stop a prescription yourself because you suspect it affects erections. A clinician can discuss alternatives and the balance of benefits and risks. [1]

    Prescription medicines can help blood flow

    PDE5 inhibitors can help people obtain and maintain erections. They are not suitable for everyone, and sexual stimulation is still relevant with sildenafil. Follow the prescribed product’s instructions rather than combining products or increasing the dose independently. [1][2]

    Nitrates are a critical interaction

    Sildenafil must not be used with nitrate medicines such as nitroglycerin or with nitrate/nitrite recreational products known as poppers. Tell the prescriber and pharmacist about all medicines and substances before starting an ED drug. [2]

    A device or counselling may address a different need

    NIDDK includes vacuum erection devices and counselling among options. Testosterone is relevant only in selected circumstances such as confirmed low levels; a testosterone-boosting supplement is not a universal treatment for maintaining an erection. [1]

    Bring the actual supplement to the review

    Imagine someone uses a sexual-enhancement blend while considering sildenafil. The clinician needs the full formula and other medicines, not just the brand name. NIDDK advises discussing supplements and online ED medicines first because interactions can cause serious problems. [1]
