What Is Tadalafil and How Does It Work?

Tadalafil is a prescription medicine used to treat erectile dysfunction (ED) in men [3][4]. It belongs to a group of medicines called PDE5 inhibitors, which work by relaxing blood vessels in the penis, allowing increased blood flow when you are sexually aroused. Tadalafil does not cause an erection on its own—sexual stimulation is still needed for it to work [4].

Tadalafil is available in two forms: on-demand tablets (10mg or 20mg taken at least 30 minutes before sex, with effects lasting up to 36 hours) and daily low-dose tablets (2.5mg or 5mg taken every day) [4]. The branded version is called Cialis, but generic tadalafil is equally effective and more affordable. At Cured Pharmacy, all tadalafil prescriptions are issued following an online consultation reviewed by a UK-registered prescriber.

Common side effects include headache, indigestion, back pain, muscle aches, flushing, and a blocked or runny nose [4]. These are usually mild and short-lived. Tadalafil must not be taken with nitrates, nicorandil, riociguat, poppers, or another PDE5 inhibitor, as this combination can cause a dangerous drop in blood pressure [4].

What Is Salbutamol and Why Is It Prescribed?

Salbutamol is a short-acting bronchodilator inhaler, often called a 'reliever' inhaler, used to treat asthma and chronic obstructive pulmonary disease (COPD) [1]. It works by relaxing the muscles in the airways, making it easier to breathe during an asthma attack or when you feel wheezy or breathless. Salbutamol is usually taken as needed, though some people use it regularly before exercise to prevent symptoms.

The medicine is generally very safe and works quickly—usually within a few minutes. Common side effects include a fast heartbeat, slight shakiness, headache, and muscle cramps, especially at higher doses. Salbutamol is available on prescription and can also be bought over the counter at pharmacies in certain circumstances, such as for people with a confirmed asthma diagnosis.

Because salbutamol acts on the airways rather than the cardiovascular system in the same way as some other medicines, it does not usually cause significant interactions with erectile dysfunction treatments. However, it is still important to tell your prescriber about all inhalers and medicines you use, including over-the-counter treatments and supplements.

Other Asthma and COPD Medicines

In addition to salbutamol, you may use other inhalers such as beclometasone, budesonide, fluticasone (preventer or steroid inhalers), or long-acting bronchodilators like salmeterol or formoterol. These medicines also do not have major direct interactions with tadalafil. Your prescriber will review all your respiratory medicines during your consultation to ensure tadalafil is safe and appropriate for you.

Do Tadalafil and Salbutamol Interact?

There is no major direct interaction reported between tadalafil and salbutamol [3][4]. Salbutamol works on the airways by relaxing smooth muscle in the lungs, while tadalafil works by increasing blood flow to the penis. They act on different systems in the body and do not significantly affect each other's levels or actions.

However, both medicines can occasionally cause a slight increase in heart rate or palpitations as side effects. If you experience a fast or irregular heartbeat, dizziness, or chest discomfort after using both medicines together, you should seek medical advice. This is uncommon, but it is important to be aware of how your body responds, especially when you first start tadalafil.

Your prescriber will always check your full medical history, including any heart or lung conditions, during your online consultation. If you have severe asthma, COPD, or any cardiovascular disease, your prescriber will assess whether tadalafil is suitable for you and may recommend starting on a lower dose. Never take tadalafil if you are also using nitrates, nicorandil, riociguat, or poppers, as this can cause a dangerous fall in blood pressure [4].

What Your Prescriber Checks Before Approving Tadalafil

When you request tadalafil through Cured Pharmacy, a UK-registered prescriber reviews your online consultation to ensure the medicine is safe and appropriate for you [2]. They will check your current medicines, including salbutamol and any other inhalers, to identify potential interactions. They will also ask about your medical history, including heart disease, blood pressure, stroke, liver or kidney problems, and any eye conditions.

The prescriber will assess whether sexual activity is safe for you. Tadalafil is not suitable if you have had a recent heart attack or stroke, unstable angina, severe heart failure, very low blood pressure, or if your doctor has advised you to avoid sexual activity [4]. If you have well-controlled asthma or COPD and no other contraindications, tadalafil is usually safe to use.

You must declare all medicines you take, including prescription medicines, over-the-counter treatments, herbal remedies, and recreational drugs. This includes any alpha-blockers (such as tamsulosin or doxazosin), blood pressure medicines, or medicines that affect liver enzymes. The prescriber may adjust your tadalafil dose or advise against treatment if there is a risk of interaction.

Alpha-Blockers and Other Blood Pressure Medicines

If you take an alpha-blocker for an enlarged prostate or high blood pressure, there is a risk of low blood pressure and dizziness when combined with tadalafil [4]. You should be stable on your alpha-blocker before starting tadalafil, and your prescriber will usually recommend the lowest dose initially. Always inform your prescriber if you take any blood pressure medicines, as they can add to the blood-pressure-lowering effect of tadalafil.

Practical Advice for Using Tadalafil and Salbutamol Together

If your prescriber approves tadalafil, you can continue using your salbutamol inhaler as normal. Take your salbutamol whenever you need it for breathlessness or wheezing, and use your tadalafil as directed—either on-demand (at least 30 minutes before sex) or daily, depending on the dose prescribed [4]. There is no need to separate the doses or avoid using them on the same day.

Keep an eye on how you feel, especially when you first start tadalafil. If you notice an unusually fast heartbeat, dizziness, chest pain, or any new or worsening symptoms, stop taking tadalafil and contact your GP or pharmacist. If you experience chest pain during sex, stop immediately and seek urgent medical help—do not take GTN spray or any nitrate medicine, as this can interact dangerously with tadalafil [4].

Avoid drinking large amounts of alcohol when using tadalafil, as this can make erectile dysfunction worse and increase the risk of dizziness and low blood pressure. Grapefruit juice can raise tadalafil levels in your blood, so it is best to avoid it. If you develop any new symptoms or your asthma or COPD worsens, speak to your GP or asthma nurse, as poorly controlled lung disease can affect your overall health and wellbeing.

When to Seek Medical Help and Warning Signs

Most men tolerate tadalafil well, but you should be aware of warning signs that need urgent attention. If you have an erection lasting more than four hours (priapism), go to A&E immediately, as this can cause permanent damage if not treated quickly [4]. Sudden loss of vision in one or both eyes, or sudden hearing loss or ringing in the ears, also requires urgent medical assessment.

If you experience chest pain, severe dizziness, fainting, or an irregular heartbeat after taking tadalafil, call 999 or go to A&E. Do not take any nitrate medicine (such as GTN spray) if you have used tadalafil in the past 48 hours, as this can cause a life-threatening drop in blood pressure [4]. Always tell paramedics or A&E staff that you have taken tadalafil.

If your erectile dysfunction is new or getting worse, see your GP for a full assessment. ED can be an early warning sign of heart disease, diabetes, or other health conditions that need treatment [1][2]. Your GP can check your cardiovascular risk, blood sugar, cholesterol, and hormone levels, and refer you to a specialist if needed. Treating the underlying cause can often improve erectile function as well as your overall health.

Managing Asthma and ED Together

If you have asthma or COPD, keeping your lung condition well controlled is important for your overall health and quality of life. Make sure you use your preventer inhaler regularly as prescribed, attend asthma reviews, and avoid triggers where possible. Good asthma control can improve your energy levels, sleep, and confidence, all of which can have a positive effect on sexual health and relationships.

When to get urgent help

• Erection lasting more than 4 hours (priapism) – go to A&E immediately
• Sudden loss of vision in one or both eyes – seek urgent medical assessment
• Chest pain during or after sex – stop activity, call 999, do not take nitrates
