Choosing the Right Strength of Sildenafil

When deciding on the appropriate strength of Sildenafil, you must consider factors like the severity of your erectile dysfunction (ED), how well your body tolerates the medication, and any underlying health conditions you may have. Sildenafil is available in three strengths: 25 mg, 50 mg, and 100 mg.

1. 25mg tablets: These are the lowest strength available and will be suitable if you are experiencing mild ED, or are taking medications that could potentially interact with sildenafil. If you have previously taken sildenafil or other erectile dysfunction treatments and found you experienced side effects, this strength may be suitable for you.
2. 50mg tablets: This is the standard starting dose for most men. It is typically prescribed to those with moderate ED who are in good health and not taking medications that could cause interactions. If you're trying Sildenafil for the first time, 50 mg is usually the recommended dose, this strength offers a balance between efficacy and the likelihood of side effects.
3. 100mg tablets: This is the highest dose of sildenafil and is generally reserved for men who do not achieve the desired effect with the 50 mg dose. It is for those with more severe ED who found the lower doses did not work for them. If you have tried 50mg tablets before and found they did not cure your ED and you did not experience any side effects, you could consider moving up to the 100mg tablets.

Always consult with a doctor or pharmacist before changing your dose, your body may respond differently to various doses, and it may take some trial and error to find the correct dosage for you. You should always start with a lower dose and if you find it to be effective with minimal side effects, there may be no need to increase your dose. If you decide to try a higher dose and it causes unwanted effects, lowering it might still provide benefit with fewer side effects. We always recommend taking the lowest dose possible.

Will My Body Get Used to Sildenafil?

The short answer is that Sildenafil generally does not cause tolerance, this means that most men will continue to experience the same level of effectiveness without needing to increase the dosage over time. If you find the tablets are not as effective as when you first started them it may be due to other factors such as changes in lifestyle or health, psychological factors, worsening of any underlying conditions and you should consult your doctor if you have any concerns.

How it works

Sildenafil is a PDE-5 inhibitor. It works by blocking phosphodiesterase type-5 which helps to relax and widen the blood vessels to the penis. This allows an increase in blood flow to the penis, making it easier to maintain an erection when sexually aroused.
To note: Sildenafil only works when sexually aroused and will not help you get an erection without stimulation.

Is Sildenafil safe?

Sildenafil has been widely studied and is considered safe for most people when used as directed and has been proven to be safe to take for a long time. There do not seem to be any lasting harmful effects from taking it for many months and years. However like all medication it can come with risks and it can cause: headaches, flushing, upset stomach, nasal congestion, and dizziness. If you have previously been diagnosed with any heart problems, take a nitrate, have severe liver impairment, or have a history of stroke or heart attack it may not be suitable for you. If you are a healthy individual it is unlikely to cause you any problems outside of the minor side effects.

How to take Sildenafil

Sildenafil is usually taken approximately 1 hour before sexual activity. It usually has a starting dose of 50mg, which can then be adjusted according to response. It is recommended to try Sildenafil a few times before trying something else. If you find 50mg aren't producing enough of an effect, the dose can be increased to 100mg. On the other hand if you find you are experiencing side effects from the 50mg tablets, you can try the lower strength dose of 25mg which can still successfully treat ED.
Sildenafil usually takes between 30 minutes to 1 hour to work, but the onset of effect may be delayed if taken with food. Once taken it usually lasts 4 – 5 hours and you should not take more than one ED treatment in a 24 hour period.

Getting the best results

To achieve the best results from sildenafil, it’s important to use it correctly. Here are some tips to maximize the benefits of sildenafil:

1. Take it in advance: Sildenafil should be taken about 30 minutes to an hour before sexual activity, allowing the medication to be absorbed and become effective.
2. Window of effectiveness: The effects will last for about 4 to 6 hours when taken, so plan accordingly, keep in mind that it won’t cause an erection without sexual stimulation.
3. Avoid big meals: While it can be taken with or without food, taking it after a high-fat meal (e.g., pizza, burgers) can slow down its absorption and delay its effects. For best results, take it on an empty stomach .
4. Avoid alcohol: Alcohol does not interact with sildenafil directly but it can make it more difficuly to get an erection.
5. Don’t rush: Give it time to work, and don’t get discouraged if it doesn’t work immediately, it might take a few attempts to see the full effect.
6. Keep relaxed: Anxiety about sexual performance can counteract the effects of sildenafil, try and keep relaxed.
7. Regular check-ups: Regular follow-ups with your doctor can help identify and manage any underlying causes of erectile dysfunction.

If you take more Sildenafil than you should

Taking more than 100 mg of the medication might cause more side effects. It's also important to know that taking a higher dose than 100mg won't make the medication work any better. I If you have any questions or run into problems, please reach out to a healthcare professional for advice.

Identifying the cause of ED can help improve treatment outcomes. Psychological factors such as stress and anxiety are the most common cause of ED. Easing stress and anxiety can help reduce ED as well as improve overall health.

Common causes include:

1. Heart disease
2. High blood pressure
3. High cholesterol levels
4. Obesity
5. Excessive alcohol consumption
6. Smoking
7. Low testosterone

Treating the conditions listed above can help with your ED problem and may reduce the need for treatment.
Therapy can help with stress or anxiety induced ED and these include:
Counseling: A therapist will help to identify and address any major stress or anxiety, helping you manage them.
Cognitive behavioural therapy (CBT): A therapist will work with you to help you manage your problems by changing the way you think and behave.
Sex therapy: A sex therapist will listen to you describe your problems and assess whether the cause is likely to be psychological, physical or a combination of the two. They can also help with worries caused by a lack of knowledge surrounding sex and addressing any emotional issues.
Other ways of reducing stress and anxiety include alternative therapies such as:
Yoga
Meditation
Relaxation techniques
Research shows these treatments can help manage and reduce your stress and anxiety levels.
There is less evidence supporting these alternative therapies compared to more traditional therapies, however they may provide additional benefits when used alongside any ED treatments you are prescribed.

Sildenafil combined with other erectile dysfunction treatments

Sildenafil should not be combined with other PDE5 inhibitors like tadalafil (Cialis), vardenafil (Levitra), or avanafil (Stendra). As these medication all work very similarly and are all PDE5 inhibitors, taking them all together can lead to an overdose, significantly increasing the risk of severe side effects, including a dangerous drop in blood pressure. This is why you should always leave at least 24 hours bewteen trying a different medication to treat erectile dysfunction.
Other treatments such as lifestyle changes, counselling and dietary changes can also be done alongside taking sildenafil and can improve treatment outcomes.

Sildenafil and graprefruit juice

It may sound strange but grapefruit juice can increase the levels of sildenafil in the bloodstream. This happens because grapefruit juice inhibits the action of an enzyme called CYP3A4 in the liver and intestines. This enzyme is responsible for breaking down sildenafil in your body. Therefore when grapefruit juice is consumed, it will inhibit and reduce the activity of CYP3A4, leading to higher levels of sildenafil in your bloodstream. This could potentially lead to an increased risk of side effects. To prevent these interactions, it's best to avoid grapefruit and grapefruit juice while taking sildenafil.

Manufacturers of Sildenafil

As Sildenafil is a generic medicine there are many different manufacturers we usually stock: TEVA, Accord, Dr Reddys and Milpharm. Although they are all different brands the manufacturers must all meet the same MHRA requirements and therefore they contain the exact same amount of active ingredient, this means that TEVA Sildenafil, Accord Sildenafil, Milpharm Sildenafil etc. should all work the same as eachother.
However some people do prefer specific brands and in some cases find they work better. We may not have each of these brands in stock when you order, so if you require a specific brand please check with us first via email. If for example you wanted TEVA Sildenafil tablets and it wasn't in stock we may be able to order it specifically for you but this will likely result in a one day delay to your order as we wait for them to come into stock.

Sildenafil vs Tadalafil (Cialis)

Tadalafil or Cialis is another form of medication that is used to treate ED. Like Sildenafil it starts to work in around 30 minutes, but lasts much longer than Sildenafil does with an effect seen for up to 36 hours. For this reason it is known as the 'weekend' pill. This does not mean you will have an erection that lasts 36 hours more that you will be able to get and maintain an erection when sexually aroused in a 36 hour period. This longer duration can be a drawback if you experience side effects as the drug will remain in your system for up to 36 hours compared to Sildenafil which will begin to wear off after 4 hours.
Sildenafil has been around longer than Tadalafil but Tadalafil has been around as Cialias since 2003 when it was first manufactuered. Both are safe and effective treatements for ED. The use of either tablet tends to come down to personal preference.

Drowsiness

This medicine can cause dizziness and can affect vision in some people. If you have not previously taken this medication, take a dose first to see how you react before you drive or use machinery.
