It's essential to take sildenafil precisely as prescribed by a healthcare professional, such as a doctor or pharmacist, to ensure both safety and effectiveness in treatment.
Dosage and strength for erectile dysfunction
Sildenafil tablets available for the treatment of erectile dysfunction are produced in multiple strengths, specifically ranging from 25mg to as high as 100mg, allowing for tailored dosing to individual needs.
The typical recommended dose for adult males is 50mg, taken as needed prior to sexual activity, with a strict limit of one dose per day to avoid potential complications.
Depending on efficacy and tolerability, the dosage may be adjusted; it can be increased to 100mg or decreased to 25mg in accordance with individual response and the physician's recommendations.
For optimal results, sildenafil should be taken no more than 4 hours before engaging in sexual intercourse. It’s crucial to understand that sildenafil will not produce an erection without sexual stimulation, as sexual excitement is necessary for it to be effective.
Dosage and strength for pulmonary hypertension
For patients dealing with pulmonary hypertension, sildenafil tablets are available in strengths of 10mg and 20mg, which are specifically formulated for this condition.
The usual prescription for adults is 20mg, administered three times daily, ensuring steady and effective management of their symptoms.
In pediatric cases, dosages may vary based on the child's weight, typically ranging from 10mg to 20mg, also taken three times daily, but the total daily limit should not exceed the prescribed amount.
How to take tablets
When taking sildenafil tablets, it is important to swallow them whole with a sufficient amount of water or juice, however, grapefruit juice should be strictly avoided as it can interact negatively with the medication.
To enhance the efficacy of sildenafil for erectile dysfunction, it is recommended to take the medication on an empty stomach, as the presence of food may delay its absorption and onset of action.
How to take liquid
If you or your child are prescribed the liquid formulation of sildenafil, note that 1ml typically corresponds to a 10mg tablet, but it’s imperative to always refer to the specific medicine label for accurate information and dosing.
Liquid formulations of sildenafil are usually prepared by your pharmacist, ensuring the proper concentration and dosage tailored to individual needs.
Your pharmacist will provide a plastic syringe or a measuring spoon to facilitate accurate dosing; it is critical that you do not use a regular kitchen teaspoon, as it does not provide an accurate measurement and could result in improper dosing.
If you forget to take it
In the event that you forget to take a dose of sildenafil for pulmonary hypertension, you should take it as soon as you remember, unless your next scheduled dose is almost due, in which case you should skip the missed dose and resume your regular dosing schedule without doubling up.
It's crucial never to take two doses at the same time as this could lead to an overdose and increase the risk of side effects. If you find that you frequently miss doses, setting a daily alarm may be beneficial.
You might also consider consulting your pharmacist for additional guidance on strategies to help you remember to take your medication consistently and effectively.
If you take too much
Taking more than the recommended dose of sildenafil can lead to a variety of unpleasant and potentially serious side effects that may require medical attention.
If you suspect you have taken too much sildenafil and are experiencing concerning symptoms, it’s important to consult with your doctor or seek emergency medical advice, especially if you experience any of the following side effects:
- persistent headaches
- dizziness or lightheadedness
- indigestion or abdominal discomfort
- nasal congestion or blocked nose
- any changes to your vision, such as blurriness
