It's important to take sildenafil as advised by a doctor or pharmacist to ensure the effectiveness and safety of the treatment.
Dosage and Strength for Erectile Dysfunction
Sildenafil tablets come in various strengths, including 25mg, 50mg, and 100mg, to cater to different needs.
The standard starting dose for erectile dysfunction is 50mg, which should be taken when needed. It is crucial not to exceed one dose in a 24-hour period.
Depending on individual response and tolerability, the dose can be adjusted up to a maximum of 100mg or down to 25mg, based on medical advice.
For optimal results, sildenafil can be taken up to 4 hours prior to sexual activity. However, sexual stimulation is necessary for the medication to work effectively.
Dosage and Strength for Pulmonary Hypertension
For pulmonary hypertension, sildenafil is available in 10mg and 20mg tablets.
The typical dosage for adults is 20mg, taken three times daily, spaced evenly throughout the day.
In pediatric cases, doses range from 10mg to 20mg, also administered three times daily, adjusted according to the child's weight and under medical guidance. It is important not to take sildenafil more than three times a day.
How to Take Tablets
Sildenafil tablets should be swallowed whole with a drink of water or juice, avoiding grapefruit juice due to potential interactions.
For best effectiveness in treating erectile dysfunction, it is recommended to take sildenafil on an empty stomach. Consuming it with a meal may delay its onset of action.
How to Take Liquid Sildenafil
If sildenafil is prescribed in liquid form, 1ml typically corresponds to a 10mg dosage; always verify with the medicine label.
Liquid formulations are usually compounded by a pharmacist, ensuring the correct concentration and dosage.
The liquid medication will come with a dosing syringe or spoon to ensure accurate measurement. If a suitable measuring device is not available, request one from your pharmacist. Avoid using a regular kitchen teaspoon as it may lead to incorrect dosing.
If You Forget a Dose
In the case of forgotten doses for pulmonary hypertension, take the missed dose as soon as you remember unless it is close to the time for your next scheduled dose. If so, skip the missed dose and proceed with the regular dosing schedule.
Never take two doses simultaneously, and do not take an extra dose to compensate for a missed one.
If you frequently miss doses, consider setting an alarm to remind you, or consult your pharmacist for additional strategies to help you remember your medication schedule.
If You Take Too Much
Exceeding the recommended dosage of sildenafil can lead to unpleasant side effects, which may vary in severity.
If you suspect you have taken too much sildenafil, it is important to consult your doctor or healthcare provider, especially if you experience any of the following side effects:
- Headaches
- Dizziness
- Indigestion
- Blocked nose
- Changes in vision
