Like all medicines, tadalafil can cause side effects in some individuals. It's important to note that while many users experience no side effects, some might encounter mild to moderate symptoms. Understanding these potential side effects can prepare you for any unexpected reactions.
Common side effects
Common side effects of tadalafil occur in more than 1 in 100 patients. These are generally mild and transient, meaning they typically resolve without the need for intervention. If you're prescribed tadalafil to treat erectile dysfunction, it's unlikely you'll face significant side effects since the duration of use is often short-term.
However, if you take tadalafil for managing pulmonary hypertension, you may encounter these side effects more frequently, and it's critical to know how to manage them effectively:
Headaches
If you experience headaches, it is advisable to ensure adequate rest and hydration. It is important to limit the intake of alcohol during this period. Consulting your pharmacist for a suitable over-the-counter painkiller can be beneficial. Typically, headaches associated with tadalafil use diminish after the initial week of treatment. Should they persist or intensify beyond this period, a discussion with your doctor is imperative.
Feeling sick (nausea)
To alleviate feelings of nausea, focus on consuming bland and simple meals while steering clear of rich, greasy, or spicy foods. If you’re treating pulmonary hypertension, taking tadalafil after meals can minimize nausea's impact.
Facial flushing and hot flushes
If you experience facial flushing, consider reducing your consumption of caffeinated beverages, such as coffee or tea, as well as alcohol. Maintaining a cool environment and utilizing a fan can also provide relief. Alternatively, splashing your face with cool water or sipping on cold beverages may help alleviate the flushing sensation, which usually resolves within a few days.
Indigestion
For those experiencing indigestion, antacids can be effective in providing relief. However, if symptoms persist and become bothersome, do not hesitate to consult your physician, who may be able to prescribe additional medications to protect your stomach.
Stuffy nose
If you find yourself dealing with nasal congestion, a consultation with your pharmacist or healthcare provider can offer insight into suitable nasal sprays that may alleviate this discomfort.
Muscle aches
In the event of experiencing unusual muscle aches unrelated to physical activity, it is advisable to consult your pharmacist for recommendations on appropriate pain relief. If muscle pain persists longer than expected, a follow-up with your doctor is warranted.
Generally, side effects will resolve upon discontinuation of tadalafil. If guidelines for managing side effects do not yield relief and they persist, seek advice from your doctor or pharmacist for further assistance.
Serious side effects
While serious side effects are uncommon, they can occur in less than 1 in 1,000 cases. Awareness of these serious reactions is crucial for timely intervention.
Urgent advice: Go to A&E immediately if:
- you experience sudden loss of vision or abrupt hearing difficulties – discontinue tadalafil if you encounter these issues
- you develop a prolonged painful erection, particularly if it lasts over 2 hours
Locate your nearest A&E facility.
Immediate action required: Call 999 right away if:
- you experience a seizure or convulsion
- you suffer from chest pain
Should any of these symptoms arise, stop taking tadalafil immediately.
If chest pain occurs during or after sexual activity and you regularly use nitrates, such as glyceryl trinitrate (GTN), do not administer them for chest pain relief.
Information:
Do not attempt to drive yourself to A&E.
The emergency operator will provide guidance on the next steps to take.
Serious allergic reaction
In rare instances, tadalafil can trigger a severe allergic reaction (anaphylaxis). Recognizing early symptoms is vital to ensure prompt treatment.
Immediate action required: Call 999 instantly if:
- your lips, mouth, throat, or tongue swell unexpectedly
- you face rapid or difficult breathing (you may feel wheezy or struggle for air)
- your throat tightens, or swallowing becomes a challenge
- your skin, tongue, or lips exhibit a bluish, grayish, or pale discoloration (for individuals with darker skin, this may be noticeable on the palms or soles)
- you suddenly feel extreme confusion, drowsiness, or dizziness
- someone collapses and remains unresponsive
- a child appears limp or unresponsive (their head may drop at odd angles)
A rash that is swollen, raised, itchy, blistered, or peeling may also be present, indicating a serious allergic reaction requiring emergency medical care.
Information:
Avoid driving yourself to A&E.
The emergency dispatcher will offer assistance on what steps to take next.
