Q: What is Sildenafil used for?

Sildenafil is used to treat: Erectile dysfunction Pulmonary arterial hypertension

Q: How does Sildenafil work?

How Sildenafil Works Sildenafil is used to treat two different conditions, and it works similarly for both by affecting blood vessel relaxation. Erectile Dysfunction For the treatment of erectile dysfunction, sildenafil blocks an enzyme known as phosphodiesterase type 5 (PDE5). This enzyme normally breaks down a chemical that causes the smooth muscles in the penis to relax. By inhibiting PDE5, sildenafil allows this chemical to stay active longer, which keeps the blood vessels open and increases blood flow to the area. It is important to note that sildenafil does not cause an erection by itself. Sexual stimulation is required to trigger the initial release of the chemicals needed to start the process. Pulmonary Arterial Hypertension When used for pulmonary arterial hypertension, sildenafil targets the blood vessels in the lungs. It helps these vessels relax and widen, which lowers the blood pressure in the lungs and improves the heart's ability to pump blood through them. This can help increase a person's capacity for physical activity and reduce shortness of breath.

Q: What is the dosage of Sildenafil and how do I take it?

How to Take Sildenafil Sildenafil is available as tablets, an oral suspension (liquid), or as an injection given into a vein. The way you take this medication depends on whether it is being used for erectile dysfunction or pulmonary arterial hypertension. For Erectile Dysfunction When used for erectile dysfunction, sildenafil is taken by mouth only when needed before sexual activity. It is generally recommended to take the dose about one hour before activity, though it may be taken earlier or later depending on your healthcare provider's instructions. It should not be taken more than once in a 24-hour period. You can take sildenafil with or without food. However, if you take it with a high-fat meal, it may take longer for the medication to start working. For Pulmonary Arterial Hypertension When used for pulmonary arterial hypertension, sildenafil is usually taken on a regular schedule, often three times a day. It is important to space the doses evenly throughout the day. Oral Suspension: If you are using the liquid form, shake the bottle well for several seconds before measuring a dose. Use a proper medical measuring device rather than a household spoon to ensure the correct amount. Injection: The injection form is typically administered by a healthcare professional in a medical setting. Missed Dose If you are taking sildenafil on a regular schedule for pulmonary arterial hypertension and you miss a dose, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and continue with your regular timing. Do not take two doses at once to make up for a missed one. Because sildenafil for erectile dysfunction is taken only when needed, missed doses are not applicable for that use.

Q: Is Sildenafil safe during pregnancy and breastfeeding?

Pregnancy There is limited information regarding the safety of sildenafil use during pregnancy. While animal studies have not demonstrated a risk of birth defects or miscarriage, there are no adequate and well-controlled studies in pregnant women. When sildenafil is used to treat pulmonary arterial hypertension (PAH), a serious condition affecting the lungs and heart, a healthcare provider will determine if the benefits of treatment outweigh the potential risks to the fetus. Breastfeeding Research shows that sildenafil and its active components pass into breast milk in very small amounts. However, there is no data available on the effects of the drug on a breastfed infant or on the mother's milk production. Individuals who are breastfeeding or planning to breastfeed should consult with a healthcare professional to discuss whether to continue or discontinue the medication or breastfeeding.

FDA Approval and Indications

Sildenafil was first approved by the U.S. Food and Drug Administration (FDA) in 1998. It is currently approved for two primary medical conditions:

Erectile Dysfunction (ED): Used to treat the inability to achieve or maintain an erection.
Pulmonary Arterial Hypertension (PAH): Used to improve exercise capacity and delay clinical worsening in adults with high blood pressure in the lungs.

Regulatory Classification

Sildenafil is classified as a prescription-only medication. It is not a controlled substance under the Controlled Substances Act. Because of its potential for serious drug interactions, particularly with nitrates, it must be used under medical supervision.

Safety Monitoring and Communications

The FDA monitors the safety of sildenafil through the Adverse Event Reporting System (FAERS). Over time, the FDA has updated the labeling for sildenafil products to include warnings about rare but serious risks, including:

Sudden vision loss in one or both eyes, which may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION).
Sudden decrease or loss of hearing, sometimes accompanied by dizziness or ringing in the ears.
Priapism, a painful erection lasting longer than four hours, which requires immediate medical attention to prevent permanent tissue damage.

There are currently no Risk Evaluation and Mitigation Strategies (REMS) or boxed warnings required for sildenafil products.

Pulmonary Arterial Hypertension: Many insurance plans cover sildenafil when it is prescribed for this condition.
Erectile Dysfunction: Coverage for erectile dysfunction is less consistent. Some plans may exclude these medications entirely, while others may limit the number of tablets covered per month or require a higher copayment.

Dosage Form: Prices may differ between oral tablets, oral liquids, and injectable forms.
Pharmacy Selection: Costs can vary between different retail pharmacies, mail-order services, and specialty pharmacies.
