It's important to take sildenafil as advised by a doctor or pharmacist, as following their guidance helps ensure its effectiveness and minimizes potential risks.
Dosage and strength for erectile dysfunction
Sildenafil tablets for erectile dysfunction come in different strengths ranging from 25mg to 100mg, giving options tailored to individual needs.
The usual dose is typically 50mg when you need it; however, it’s crucial not to take it more than once a day to avoid complications.
The effective dose can be adjusted based on individual response, allowing for an increase to 100mg or a decrease to 25mg based on its effect.
To maximize the benefits of sildenafil, take it up to 4 hours before you wish to engage in sexual activity, as you will need to experience sexual excitement for the medication to work properly.
Dosage and strength for pulmonary hypertension
Sildenafil tablets used for the treatment of pulmonary hypertension are available in strengths of 10mg and 20mg, providing flexibility for dosing.
For adults, the usual dosage is 20mg taken three times a day, ensuring consistent management of the condition.
In cases of pediatric patients, the dosage can vary based on weight, ranging from 10mg to 20mg taken three times a day; however, ensure not to exceed three doses within this time frame.
How to take tablets
Swallow the tablets whole, accompanied by a drink of water or juice (but please avoid grapefruit juice), to ensure proper digestion and absorption.
For the treatment of erectile dysfunction, it is advisable to take sildenafil on an empty stomach, as food may delay its effectiveness and onset of action.
How to take liquid
If you or your child are prescribed sildenafil in liquid form, typically, 1ml of the liquid will correspond to a 10mg tablet, but always verify this with the medicine label for accuracy.
Liquid sildenafil will usually be compounded specifically for you by your pharmacist, ensuring you receive the proper formulation suited to your needs.
The medication will come with a plastic syringe or spoon to help you measure the correct dose; if you need one, don’t hesitate to ask your pharmacist as kitchen teaspoons can lead to inaccurate dosing.
If you forget to take it
For patients with pulmonary hypertension, if you forget to take a dose of sildenafil, take it as soon as you remember unless it’s very close to your next scheduled dose; in that case, skip the missed dose and resume your regular dosing schedule.
It’s crucial to avoid taking two doses at the same time and never compensate for a missed dose by taking an extra one, as this can lead to adverse reactions.
If missing doses becomes a recurrent issue, consider setting an alarm as a reminder, and you can also consult your pharmacist for additional strategies to help you maintain your dosing schedule.
If you take too much
Taking excessive amounts of sildenafil can lead to uncomfortable side effects that may require medical attention.
If you suspect an overdose and are concerned about any of the following side effects, it’s important to consult your doctor promptly:
- headaches
- dizziness
- indigestion
- blocked nose
- changes to your vision
