Several types of medication can lead to erectile dysfunction- so if you develop problems with getting or sustaining an erection soon after starting a new medication you should speak to your doctor (it’s usually advisable not to stop any medication suddenly, without consulting your doctor). Common culprits include:

• Beta-blockers (eg propranolol, bisoprolol or carvedilol)- often used to treat blood pressure or other heart conditions
• Diuretics- also known as “water tablets” (eg furosemide, indapamide), often used to treat heart conditions
• Antidepressants (eg citalopram, fluoxetine) used to treat depression or anxiety
• Antihistamines (eg promethazine/phenergan, diphenhydramine) used to treat allergies
• H2 blockers (e.g. cimetidine, ranitidine) used to treat acid reflux and heartburn.

Before you seek treatment for erectile dysfunction, you should discuss your health and any medications you’re taking with your doctor.
