What Is Vardenafil and How Does It Work?

Vardenafil belongs to a group of medicines called PDE5 inhibitors, which also includes sildenafil (Viagra) and tadalafil (Cialis) [5]. When you're sexually stimulated, your body releases a chemical that relaxes the blood vessels in the penis, allowing more blood to flow in and produce an erection. An enzyme called PDE5 can break down this chemical too quickly, making it harder to get or keep an erection [1].

Vardenafil blocks the PDE5 enzyme, helping the blood vessels stay relaxed for longer and making it easier to achieve an erection when you're aroused [5]. It's important to understand that vardenafil won't cause an erection on its own—you still need sexual stimulation for it to work. The medicine simply helps your body respond more effectively to that stimulation.

Vardenafil is available in 5 mg, 10 mg, and 20 mg tablets in the UK, and it's only available on prescription after a consultation with a healthcare professional [5]. At Cured Pharmacy, our UK-registered prescribers review your medical history and current medicines during an online consultation to ensure vardenafil is safe and suitable for you.

Vardenafil First Time: Recommended Starting Dose

For most men taking vardenafil first time, the recommended starting dose is 10 mg [5]. This dose balances effectiveness with the lowest risk of side effects, allowing your prescriber to assess how well you respond to the medicine. Some men may be started on a lower 5 mg dose if they have certain health conditions, take other medicines that interact with vardenafil, or are over 65 years old [5].

Your prescriber will decide the right starting dose based on your medical history, current medications, and overall health. Never take more than the prescribed dose, and don't take vardenafil more than once in 24 hours [5]. If the 10 mg dose doesn't work well enough after a few attempts, your prescriber may increase it to 20 mg, or they may reduce it to 5 mg if you experience side effects.

It's worth noting that vardenafil may not work perfectly the first time you try it. Many men find that it takes two or three attempts to get the timing and conditions right, so don't be discouraged if your first experience isn't ideal. Speak to your prescriber if you have concerns after trying it a few times.

Who Should Start on a Lower Dose?

Men over 65, those with moderate liver problems, or those taking certain other medicines (such as some HIV treatments or antifungal medicines) may need to start on 5 mg [5]. Alpha-blockers used for prostate problems (such as tamsulosin or doxazosin) can interact with vardenafil, causing dizziness or low blood pressure, so your prescriber will ensure you're stable on the alpha-blocker and may start you on the lowest dose [5]. Always declare all your current medicines during your consultation, including over-the-counter products and herbal supplements.

When to Take Vardenafil First Time: Timing and Preparation

Vardenafil should be taken about 25–60 minutes before you plan to have sex [5]. Most men find that taking it around 30–45 minutes beforehand works well, but the exact timing can vary from person to person. The medicine is absorbed more quickly on an empty stomach, so if you've just eaten a large or high-fat meal, it may take longer to work [5].

You can take vardenafil with or without food, but a heavy meal—especially one high in fat—can delay absorption and reduce how well it works [5]. If you're taking vardenafil first time, consider taking it on an empty stomach or after a light meal to give yourself the best chance of success. Avoid drinking large amounts of alcohol, as this can make it harder to get an erection and may increase the risk of side effects such as dizziness or headache [5].

Remember that vardenafil only works when you're sexually aroused. It won't cause an automatic erection, so you'll still need foreplay and stimulation. Plan some relaxed, intimate time with your partner, and try not to put too much pressure on yourself—anxiety can make erectile dysfunction worse.

What you need to know

• The usual starting dose for vardenafil first time is 10 mg, taken 25–60 minutes before sex
• Vardenafil works only with sexual stimulation and effects last around 4–5 hours
• Avoid heavy meals and excessive alcohol to improve effectiveness
• Never take vardenafil with nitrates, nicorandil, or other ED medicines
• Try it 3–4 times before deciding it doesn't work; speak to your prescriber if needed

What to Expect When Taking Vardenafil First Time

When you take vardenafil for the first time, you may notice that it becomes easier to get and maintain an erection during sexual activity. The effects typically last for around 4–5 hours, though this varies between individuals [5]. You won't have an erection for the entire time—the medicine simply makes it easier to respond to sexual stimulation during that window.

Some men experience mild side effects, especially during the first few uses. The most common include headache, flushing (warmth or redness in the face and neck), nasal congestion, indigestion, and dizziness [5]. These side effects are usually mild and temporary, often improving as your body gets used to the medicine. Drinking plenty of water and avoiding alcohol can help reduce some of these effects.

If you experience chest pain during sex, stop immediately and seek urgent medical help—do not take nitrate medicines such as GTN spray, as the combination with vardenafil can cause a dangerous drop in blood pressure [5]. If you have an erection lasting more than four hours (priapism), or sudden loss of vision or hearing, go to A&E straight away [5].

What If Vardenafil Doesn't Work First Time?

It's not uncommon for vardenafil (or any ED medicine) to be less effective the first time you try it, especially if you're anxious or the timing wasn't quite right. Try it on at least three or four separate occasions before deciding it doesn't work for you [2]. Make sure you're taking it at the right time, avoiding heavy meals and excessive alcohol, and allowing time for sexual stimulation. If it still doesn't help after several attempts, speak to your prescriber—they may adjust your dose or suggest trying a different PDE5 inhibitor such as sildenafil or tadalafil.

Important Safety Information for Vardenafil First Time Users

Before taking vardenafil first time, it's essential to tell your prescriber about all your current medicines and health conditions. Vardenafil must never be taken with nitrates (such as GTN spray, isosorbide mononitrate, or isosorbide dinitrate), nicorandil, riociguat, or recreational drugs called 'poppers' (amyl or alkyl nitrites), as this combination can cause a life-threatening drop in blood pressure [5].

Certain medicines can affect how vardenafil works or increase the risk of side effects. Potent CYP3A4 inhibitors—including some HIV medicines (ritonavir, cobicistat), antifungals (ketoconazole, itraconazole), and antibiotics (clarithromycin)—can raise vardenafil levels in your blood, and vardenafil may be contraindicated or require dose adjustment [5]. Medicines that lower blood pressure (including some treatments for high blood pressure or prostate problems) can add to the blood-pressure-lowering effect of vardenafil, causing dizziness [5].

Vardenafil is not suitable for everyone. It should not be used if you have severe heart or liver problems, very low blood pressure, a recent stroke or heart attack, unstable angina, or a history of sudden vision loss (NAION) [5]. Your prescriber will check your suitability during the online consultation. At Cured Pharmacy, every order is reviewed by a UK-registered prescriber to ensure the treatment is safe for you.

When to get urgent help

• Chest pain during sex—stop immediately and call 999; do not take GTN or nitrates
• Erection lasting more than 4 hours (priapism)—go to A&E straight away
• Sudden loss of vision or hearing—seek urgent medical help
• Severe dizziness, fainting, or allergic reaction (rash, swelling, difficulty breathing)—call 999

Call 999 or go to A&E in an emergency, or contact NHS 111 for urgent advice.

A UK-registered prescriber will review your answers, and if vardenafil is appropriate, they'll issue a prescription [2].

Your medicine is then dispensed by our GPhC-registered pharmacy (GPhC 9012511) and delivered discreetly to your door, usually within a few days. Vardenafil (generic Levitra) is available at Cured Pharmacy for £16.95, or £13.56 for your first order with code Ednew.

If you're experiencing erectile dysfunction for the first time, it's also a good idea to see your GP.
