Sildenafil 100mg, commonly referred to by its well-known brand name Viagra, is primarily utilized to treat erectile dysfunction (ED) in men, which is defined by the inability to achieve or maintain a satisfactory erection. Additionally, Sildenafil 100mg is prescribed under alternative brand names such as Liqrev and Revatio to enhance exercise capacity in both adults and children (over 1 year old) suffering from pulmonary arterial hypertension (PAH). This medical condition is characterized by elevated blood pressure in the blood vessels that lead to the lungs. The medication falls under a category of drugs known as phosphodiesterase type 5 (PDE5) inhibitors.
Sildenafil functions by improving blood flow to the penis during sexual arousal, thereby assisting in achieving an erection. For patients diagnosed with PAH, it works by relaxing the blood vessels in the lungs, allows for smoother blood flow, and alleviates symptoms such as shortness of breath and fatigue.
This medication is available in both tablet form and as a liquid suspension for oral consumption. When used for the treatment of ED, it is typically ingested as needed, approximately one hour before engaging in sexual activity. Sildenafil can be consumed at any time ranging from 30 minutes to 4 hours prior to sexual engagement. It is generally recommended not to exceed one dose in a 24-hour period.
If sildenafil is prescribed for managing PAH, it may be taken up to three times a day, irrespective of meal timings. It is essential to follow the advice of your healthcare professional and adhere to the dosage instructions that are listed on the prescription label.
When you take the liquid formulation of sildenafil, it is necessary to thoroughly shake the bottle before each use to guarantee that the medication is properly mixed. Use the dosing syringe that comes with the medication to accurately measure your dose, and refrain from mixing the solution with other medications or flavoring agents.
For ED treatment, medical professionals usually start patients with a moderate dose of sildenafil, which can be adjusted based on individual effectiveness and tolerance. Should the medication not produce the desired results or if side effects occur, it is crucial to notify your healthcare provider as soon as possible.
For patients receiving treatment for PAH, it is vital to continue taking sildenafil even if there is an improvement in symptoms, as this medication does not provide a cure for the condition.
Sildenafil may also be prescribed for various other conditions as determined appropriate by your healthcare provider. It is advisable to speak with your doctor or pharmacist to gain more insight into additional uses of this medication.
Before Taking Sildenafil 100mg
- Inform your doctor and pharmacist of any known allergies to sildenafil or any other medications you may have.
- Be aware that certain medications can interact adversely with sildenafil. Notify your healthcare provider if you are taking any nitrates, such as isosorbide dinitrate or nitroglycerin, often prescribed for the treatment of chest pain.
- Avoid using sildenafil in conjunction with recreational drugs that contain nitrates, commonly referred to as 'poppers'.
- Ensure that you discuss all medications, supplements, or vitamins you are currently taking with your healthcare practitioner.
- Sildenafil is marketed under various brand names, but it is advised to use only one product at a time to avoid potential complications.
- Consult with your doctor regarding any over-the-counter or herbal supplements you are considering, as these might interact with sildenafil.
- Maintain transparency with your healthcare provider about your complete health history and any past medical conditions, especially heart-related issues or bleeding disorders.
- For female patients taking sildenafil for PAH, it is important to inform your doctor if you are pregnant or breastfeeding, as this could impact your treatment plan.
- During any surgical procedures, including dental work, always notify your healthcare team regarding your sildenafil usage.
- If advised by your healthcare provider to refrain from sexual activity for medical reasons, be sure to inform them of this as well.
It is important to consult your doctor about any dietary considerations, especially regarding the consumption of grapefruit juice while on this medication, as it may affect how sildenafil works in your body.
If you miss a dose of sildenafil while managing PAH, take the missed dose as soon as you remember. If it is nearly time for your next dose, skip the missed dose entirely. Do not take two doses at once.
