Tadalafil (brand name: Cialis) belongs to a group of medicines called phosphodiesterase type 5 in inhibitors. It is one of the medications available in the UK that treats Erectile Dysfunction (ED) and Benign Prostatic Hyperplasia (BPH).
Its functions include relaxing and widening of blood vessels, therefore, assisting blood flow to certain tissues, enabling men to achieve and sustain an erection. In the case of BPH, it improves urinary flow, alleviating urinary symptoms like a weak stream or difficulty starting urination.
Tadalafil can be highly effective and enhance your quality of life if used correctly. However, for optimal results and to avoid adverse effects, you must understand when and how to take it. Whether you want to optimise your routine or you are new to this medicine, this guide aims to provide the best ways to use Tadalafil safely and effectively.
How To Take Tadalafil Correctly?
You must take Tadalafil according to your doctor’s instructions to enhance its effectiveness and avoid side effects. Tadalafil tablets are oral tablets used for men only. Here is a step-by-step guide:
- Swallow the whole tablet with a glass of water. Do not crush, chew, or break the tablets, as it can affect the medicine’s effectiveness and absorption.
- The tablet can be taken with or without food.
If you are still unsure how to use it safely, read the patient leaflet carefully or consult your doctor.
The Best Time to Take Tadalafil?
Tadalafil's recommended times for intake vary according to the type of dosage prescribed. For the as-needed dose, it is best to take one tablet 30 minutes before sexual activity.
Tadalafil is intended for use before anticipated sexual activity; therefore, it may not work if there is no sexual stimulation. The effects of this medicine may last for up to 36 hours.
If you are on a daily dose, take it at the same time each day, regardless of when you plan to have sex. This maintains the steady level of the drug in your system, offering more spontaneity without the need to think about the timing of each dose.
What Are The Recommended Doses?
As is the case with most medications, Tadalafil is available in several doses and strengths. Each individual’s health condition will ultimately determine the amount prescribed.
For an as-needed dose, Tadalafil can be taken up to once daily. The usual recommended dose is 10mg before anticipated sexual activity. Based on your tolerance level and how well the medicine works, your physician may increase your dose to 20 mg or reduce it to a lower dose.
For a daily dose, the usual prescription is for Tadalafil 2.5mg or 5mg once daily, taken at the same time every day.
If you have certain health problems, such as kidney or liver problems, you need a modified schedule or a lower starting dose. Consult your doctor for a tailored treatment plan based on your health and medical history.
What Are The Side Effects & Safety Tips?
Let’s have a look at its safety tips and side effects:
Safety Tips
For safe and effective administration of Cialis:
- Do not take it with nitrate medications (used for heart problems or chest pain) as it can drop blood pressure.
- Before taking Cialis, give your physician a complete list of medications you have used or are taking to avoid drug interactions or health complications.
- Limit alcohol consumption, as excessive drinking can exacerbate the risk of dizziness and low blood pressure
Side Effects
Cialis (Tadalafil) causes some side effects in some people, although not everyone gets them. Its common side effects are:
- Headaches
- Back pain
- Indigestion
- Facial flushing
- Stuffy nose
- Muscle aches
These side effects are mild and resolve on their own with time. However, there are rare but serious side effects such as:
- Priaprism - prolonged and possibly painful erection which lasts for more than 4 hours.
- Sudden hearing or vision loss
- Chest pain - do not use nitrates but seek help immediately
- If you get any of these side effects, seek emergency help immediately.
When taking Tadalafil, avoiding common mistakes is important to ensure proper safety and efficacy. These include:
- Avoid doubling the dose, especially when a previous dose did not show results instantly, as it will open up the possibility for more serious side effects like low blood pressure and priapism (prolonged, painful erections).
- Do not consume grapefruit or grapefruit juice as it can interfere with Tadalafil, potentially leading to excessive Tadalafil concentration in the bloodstream.
- Do not ignore side effects such as chest pain, vision changes, or an erection that lasts more than four hours, as these side effects require prompt immediate medical attention.
- Do not combine Tadalafil with nitrates, or blood pressure medication, as this combination will lead to a sudden drop in blood pressure.
When Using Cialis, How Long Does it Normally Last?
The effects of Cialis (tadalafil) can last for up to 36 hours, and that is why it is referred to as a weekend pill.
It starts to kick in within 30-60 minutes after taking it. It is pivotal to keep in mind that the long duration does not mean continuous erection but an improved ability to get and maintain an erection when sexually aroused.
What Else Should You Know Before Using Cialis?
Before taking this medicine, remember that it is not an instant aphrodisiac and does not work without sexual stimulation. Limit alcohol consumption and tell your doctor if you are taking any medications or have any heart conditions, ensuring safety and avoiding the risk of serious side effects.
