It's important to take sildenafil as advised by a doctor or pharmacist, to ensure both efficacy and safety when using this medication.
Dosage and strength for erectile dysfunction
Sildenafil tablets for erectile dysfunction come in different strengths ranging from 25mg to 100mg, catering to individual needs.
The usual dose is 50mg, taken only when required, and do not exceed more than one dose in a 24-hour period to avoid potential complications.
Depending on its effectiveness and your doctor's advice, the dose can be adjusted upwards to 100mg or lowered to 25mg for optimal results.
Be sure to take sildenafil no later than 4 hours before you plan to engage in sexual activity, as being sexually aroused is necessary for the medication to work effectively.
Dosage and strength for pulmonary hypertension
For the treatment of pulmonary hypertension, sildenafil is available in strengths of 10mg and 20mg, specifically formulated for this condition.
The standard adult prescription is typically 20mg administered three times daily, allowing for steady control of the symptoms associated with pulmonary hypertension.
Pediatric dosing may vary, typically ranging from 10mg to 20mg three times a day, depending on the child's weight and specific needs. It is essential to adhere to the prescribed frequency of three doses per day.
How to take tablets
Swallow the tablets whole with a sufficient amount of water or juice, but it is advisable to avoid grapefruit juice as it can affect the absorption of the medication.
For best results with erectile dysfunction, it is recommended to take sildenafil on an empty stomach, as food can delay its effectiveness and onset of action.
How to take liquid
If you or your child require sildenafil in liquid form, typically, 1ml corresponds to the dosage of a 10mg tablet, but please verify this with the medicine label for accuracy.
Liquid sildenafil is often compounded specifically for you by your pharmacist, ensuring the correct concentration and dosage.
The liquid formulation will include a plastic syringe or measuring spoon to assist you in taking the precise amount; it's crucial to avoid kitchen spoons due to inaccuracy in measurement.
If you forget to take it
In the case of pulmonary hypertension, if a dose of sildenafil is missed, take it as soon as you remember unless the next dose is approaching; in that case, simply skip the missed dose and proceed with your regular schedule.
Never take two doses simultaneously, and do not attempt to compensate for a missed dose by taking an extra one, as this can lead to adverse effects.
If you frequently forget to take your medication, consider setting an alarm or reminder to assist you; you may also consult your pharmacist for additional strategies to reinforce your medication adherence.
If you take too much
Taking an excessive amount of sildenafil can lead to unwanted side effects, and it is crucial to be aware of these potential consequences.
If you suspect you've taken too much sildenafil and are concerned about experiencing side effects, please consult your doctor without delay for guidance and appropriate care.
