Hydroxyzine and Erectile Dysfunction: What You Need to Know
Published: 12 November 2026
Hydroxyzine erectile dysfunction is a concern for some men taking this antihistamine medication. While hydroxyzine is primarily prescribed for anxiety and itching, sexual side effects including difficulty achieving or maintaining an erection are occasionally reported. This page explains how hydroxyzine may affect erectile function, what you should never do if you experience problems, and the treatment options you can discuss with your prescriber.
Key takeaways
- Hydroxyzine can occasionally cause erectile difficulties, though this is uncommon and many men experience no sexual side effects
- Never stop or reduce hydroxyzine without medical advice, as your original symptoms may return or worsen
- ED tablets like sildenafil and tadalafil can usually be used with hydroxyzine after a prescriber consultation
- Erectile dysfunction can signal underlying health issues, so see your GP for a full assessment
- Your prescriber can adjust your dose, switch medications, or prescribe ED treatment if needed
Can Hydroxyzine Cause Erectile Dysfunction?
Hydroxyzine is an antihistamine commonly prescribed for anxiety, allergic skin conditions, and itching. Sexual side effects, including erectile dysfunction, are not among the most frequently reported adverse effects, but they can occur in some men [12]. The mechanism is not fully understood, but hydroxyzine has sedative and anticholinergic properties that may indirectly affect sexual function.
Anticholinergic effects can interfere with the nervous system signals needed for arousal and erection. Additionally, the sedative properties of hydroxyzine may reduce libido or sexual interest, which can contribute to difficulties with erections. It's important to note that individual responses vary considerably—many men take hydroxyzine without experiencing any sexual side effects at all.
If you notice new or worsening erectile difficulties after starting hydroxyzine, it's worth discussing with your prescriber. However, anxiety itself (the condition hydroxyzine often treats) is a well-recognised cause of erectile dysfunction [1]. Distinguishing between medication side effects and the underlying condition can be challenging, which is why professional guidance is essential.
How Common Is Hydroxyzine Erectile Dysfunction?
The exact prevalence of erectile dysfunction specifically caused by hydroxyzine is not well documented in large-scale clinical trials. Sexual side effects are listed as possible but uncommon adverse reactions in the product information [12]. This suggests that while ED can occur, it affects only a minority of men taking the medication.
It's worth remembering that erectile dysfunction is common in the general population, affecting approximately 40% of men over 40 to some degree [10]. Many factors contribute to ED, including cardiovascular health, diabetes, stress, anxiety, depression, and other medications. When ED develops during hydroxyzine treatment, it may be coincidental rather than directly caused by the drug.
If you're experiencing erectile difficulties while taking hydroxyzine, don't assume the medication is definitely to blame. A thorough assessment by your GP or prescriber can help identify all contributing factors. They may suggest monitoring symptoms, adjusting the dose, or exploring alternative treatments for your underlying condition if hydroxyzine appears to be the culprit.

What NOT to Do If You Experience Erectile Problems on Hydroxyzine
Never stop taking hydroxyzine suddenly without speaking to your prescriber first. Hydroxyzine is often prescribed for anxiety or chronic itching, and stopping abruptly may cause your original symptoms to return or worsen. If the medication is being used for anxiety, sudden discontinuation could lead to a rebound increase in anxiety levels.
Similarly, do not reduce your dose or skip doses on your own in an attempt to improve erectile function. Changes to your medication regimen should always be made under medical supervision. Your prescriber needs to balance the benefits of hydroxyzine for your primary condition against any side effects you're experiencing.
Avoid taking any erectile dysfunction treatment without declaring your hydroxyzine use during the consultation. While there is no major documented interaction between hydroxyzine and PDE5 inhibitors (the main class of ED tablets), your prescriber or pharmacist must review your complete medication list to ensure safety. Self-medicating or buying ED treatments from unregulated sources is dangerous and may lead to serious health consequences.
The Importance of Professional Guidance
Your prescriber is best placed to assess whether hydroxyzine is contributing to erectile difficulties. They can review your medical history, current medications, and overall health to determine the most likely cause. In some cases, the timing of when ED started relative to beginning hydroxyzine can provide useful clues.
If hydroxyzine is identified as a probable cause, your doctor may suggest alternative treatments for your anxiety or skin condition that are less likely to affect sexual function. There are many effective options available, and finding the right balance between managing your primary condition and maintaining quality of life is entirely achievable with professional support.
Options to Discuss With Your Prescriber for Hydroxyzine Erectile Dysfunction
If you're experiencing erectile difficulties while taking hydroxyzine, several options are worth discussing with your prescriber. The right approach depends on how well hydroxyzine is controlling your symptoms, whether other factors are contributing to ED, and your overall health and preferences.
One option is to review the dose of hydroxyzine. Sometimes a lower dose can still manage anxiety or itching effectively while reducing the likelihood of side effects. Your prescriber may also consider switching to an alternative medication with a different side-effect profile. For anxiety, options might include SSRIs, SNRIs, or other anxiolytics; for itching, non-sedating antihistamines or topical treatments may be suitable.
Another approach is to address the erectile dysfunction directly while continuing hydroxyzine if it's working well for your primary condition. This might involve lifestyle modifications such as increasing physical activity, reducing alcohol intake, managing stress, or addressing cardiovascular risk factors [1][2]. If these measures are insufficient, your prescriber may consider prescribing an oral ED treatment such as sildenafil or tadalafil, provided there are no contraindications.
Your GP may also want to investigate other potential causes of erectile dysfunction, particularly if you have risk factors for cardiovascular disease or diabetes. ED can be an early warning sign of these conditions [1], so a broader health check may be recommended. This holistic approach ensures that any underlying health issues are identified and managed appropriately.
Don't Stop Your Medication
If you're experiencing erectile difficulties while taking hydroxyzine, speak to your prescriber before making any changes. They can help identify the cause and suggest safe solutions, whether that's adjusting your dose, switching medication, or prescribing ED treatment alongside your current therapy.
Can You Use ED Tablets With Hydroxyzine?
There is no major documented interaction between hydroxyzine and PDE5 inhibitor medications such as sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), or avanafil (Spedra) [3][4][5][6]. This means that, in principle, these ED treatments can usually be considered for men taking hydroxyzine, provided they are otherwise suitable candidates.
However, it is essential that your prescriber or pharmacist reviews your complete medical history and current medications during the consultation. Both hydroxyzine and some ED tablets can cause drowsiness or dizziness, and combining them may increase these effects in some individuals. Your prescriber will assess whether this combination is appropriate for you personally.
PDE5 inhibitors are not suitable for everyone. They must never be taken with nitrates (such as GTN spray or isosorbide mononitrate), nicorandil, riociguat, or recreational drugs known as 'poppers', as this combination can cause a dangerous drop in blood pressure [3][4][5][6]. They are also unsuitable for men with certain heart conditions, very low blood pressure, or recent stroke or heart attack. Your prescriber will check for these contraindications before prescribing.
At Cured Pharmacy, all ED treatments require an online consultation reviewed by a UK-registered prescriber. During this consultation, you will be asked about all medications you currently take, including hydroxyzine, to ensure any treatment is safe and appropriate for you. Never purchase ED tablets from unregulated sources or without declaring your full medication list.
How PDE5 Inhibitors Work
PDE5 inhibitors work by increasing blood flow to the penis in response to sexual stimulation. They do not cause automatic erections—sexual arousal is still required. Sildenafil (Viagra) is usually taken about one hour before sex and lasts for around four to six hours. Tadalafil (Cialis) can be taken on-demand (effective within 30 minutes and lasting up to 36 hours) or as a lower daily dose [3][4].
Vardenafil (Levitra) works similarly to sildenafil, taking effect in 25 to 60 minutes, while avanafil (Spedra) is the fastest-acting option, working in as little as 15 to 30 minutes [5][6]. Your prescriber can help you choose the most suitable option based on your lifestyle, preferences, and any other health considerations.
When to See Your GP About Hydroxyzine and Erectile Dysfunction
If you develop erectile difficulties for the first time while taking hydroxyzine, it's important to see your GP for a full assessment. Erectile dysfunction can be an early indicator of cardiovascular disease, diabetes, or other health conditions that require investigation and management [1][2]. Your GP can arrange blood tests to check cholesterol, blood sugar, and hormone levels, and assess your cardiovascular risk.
You should also see your GP if erectile problems are affecting your mental health, relationship, or quality of life. ED is a common and treatable condition, and there is no need to suffer in silence. Your doctor can discuss the full range of treatment options, from lifestyle changes to medication, and help you find an approach that works for you.
If you experience sudden or severe erectile dysfunction, chest pain during sexual activity, or an erection lasting more than four hours (priapism), seek urgent medical attention. These symptoms may indicate a serious underlying problem that requires immediate treatment. Similarly, sudden loss of vision or hearing while taking ED medication is a medical emergency and you should stop the medication and seek help immediately [3][4].
Remember, your GP is there to support you with all aspects of your health, including sexual health. Open and honest communication about your symptoms and concerns will help them provide the best possible care and ensure that any treatment plan is safe and effective for your individual circumstances.
Lifestyle Factors That Can Help
Regardless of whether hydroxyzine is contributing to erectile difficulties, certain lifestyle changes can improve erectile function and overall health. Regular physical activity, maintaining a healthy weight, eating a balanced diet, reducing alcohol intake, and stopping smoking all have proven benefits for erectile function [1][2].
Managing stress and anxiety through relaxation techniques, mindfulness, or talking therapies can also be helpful, particularly if anxiety is a contributing factor. If hydroxyzine is treating an anxiety disorder, ensuring that the underlying condition is well managed may indirectly improve sexual function. Your GP can refer you to appropriate support services if needed.
When to get urgent help
- Erection lasting more than 4 hours (priapism) – go to A&E immediately
- Sudden loss of vision or hearing while taking ED medication – stop the medication and seek urgent medical help
- Chest pain during sexual activity – stop and call 999
- Severe dizziness or fainting after taking ED tablets – seek same-day medical advice
- Allergic reaction (swelling of face, lips, tongue, or difficulty breathing) – call 999
Call 999 or go to A&E in an emergency, or contact NHS 111 for urgent advice.

Does hydroxyzine always cause erectile dysfunction?
No, sexual side effects from hydroxyzine are uncommon and many men take it without experiencing any erectile difficulties. Individual responses vary considerably.
Can I stop taking hydroxyzine if it's affecting my erections?
Never stop hydroxyzine without speaking to your prescriber first, as this may cause your original symptoms to return or worsen. Discuss your concerns so they can suggest safer alternatives.
Is hydroxyzine erectile dysfunction permanent?
Sexual side effects from medications are usually reversible. If hydroxyzine is the cause, symptoms typically improve after dose adjustment, switching medication, or stopping treatment under medical supervision.
Can I take Viagra or Cialis with hydroxyzine?
There is no major documented interaction between hydroxyzine and PDE5 inhibitors like sildenafil or tadalafil, but you must declare all medications during your consultation so your prescriber can check suitability.
How long after starting hydroxyzine might erectile problems appear?
The timing varies between individuals. Some men notice changes soon after starting treatment, while others may not experience any issues at all. Report any new symptoms to your prescriber.
Could my erectile problems be caused by anxiety rather than hydroxyzine?
Yes, anxiety itself is a well-recognised cause of erectile dysfunction. Your prescriber can help distinguish between medication side effects and symptoms of your underlying condition.
Are there antihistamines that don't affect erections?
Non-sedating antihistamines such as cetirizine or loratadine are less likely to cause sexual side effects, but they treat different conditions. Your prescriber can advise on suitable alternatives for your specific needs.
Should I see my GP about erectile dysfunction even if I think it's just the hydroxyzine?
Yes, it's important to see your GP for a full assessment, as erectile dysfunction can be an early sign of cardiovascular disease or diabetes that requires investigation and treatment.
