Common Use

ED medications are used to treat erectile dysfunction, a condition characterized by the inability to achieve or maintain an erection sufficient for sexual intercourse. These medications work by increasing blood flow to the penis, helping to achieve and maintain an erection. Common ED medications include sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Stendra).

Dosage and Direction

The dosage of ED medications varies depending on the specific drug and the individual's needs. Here are general guidelines for the common ED medications:

• Sildenafil (Viagra): Typically taken as needed, about 30 minutes to 1 hour before sexual activity. The usual starting dose is 50 mg, but it can be adjusted to 25 mg or 100 mg based on effectiveness and tolerance.
• Tadalafil (Cialis): Can be taken as needed or daily. For as-needed use, the typical starting dose is 10 mg, taken at least 30 minutes before sexual activity. For daily use, the dose is usually 2.5 mg to 5 mg once daily.
• Vardenafil (Levitra): Taken as needed, about 30 minutes before sexual activity. The usual starting dose is 10 mg, which can be adjusted to 5 mg or 20 mg based on effectiveness and tolerance.
• Avanafil (Stendra): Typically taken as needed, about 15 to 30 minutes before sexual activity. The usual starting dose is 100 mg, which can be adjusted to 50 mg or 200 mg based on effectiveness and tolerance.

Always follow your healthcare provider's instructions and do not adjust the dose without consulting them.

Precautions

Before starting ED medications, discuss your medical history with your healthcare provider, particularly if you have any of the following conditions:

• Heart disease or heart rhythm problems
• High or low blood pressure
• History of stroke or heart attack
• Kidney or liver disease
• Stomach ulcers
• Retinitis pigmentosa (a rare genetic eye condition)
• Peyronie's disease (penis curvature)

Pregnant or breastfeeding women should consult their healthcare provider before using ED medications. These medications are not recommended for individuals under 18 years of age.

Contraindications

ED medications are contraindicated in patients with:

• Severe heart or liver problems
• Recent stroke or heart attack
• Low blood pressure
• Known hypersensitivity to the medication
• Those taking nitrates for chest pain (angina)

Possible Side Effects

Like all medications, ED medications may cause side effects. Common side effects include:

• Headache
• Flushing
• Indigestion
• Nasal congestion
• Dizziness
• Visual disturbances

These side effects are usually mild and temporary. However, if you experience severe side effects such as chest pain, severe dizziness, or an erection lasting more than four hours (priapism), seek medical attention immediately.

Drug Interactions

ED medications may interact with other medications, which can affect their efficacy or increase the risk of adverse effects. Be sure to inform your healthcare provider about all the medications you are taking, including prescription and over-the-counter drugs, vitamins, and herbal supplements. Significant drug interactions may include:

• Nitrates for chest pain
• Alpha-blockers for high blood pressure or prostate problems
• Other ED medications
• Some antifungal and antibiotic medications
• Medications for HIV/AIDS
• Some heart medications

Missed Dose

Since ED medications are usually taken as needed, there is no regular dosing schedule. If you are taking a daily dose (such as daily Tadalafil), take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses at the same time to make up for a missed dose.

Overdose

In case of an overdose, seek immediate medical attention. Symptoms of an overdose may include severe dizziness, fainting, or a prolonged erection (priapism) that lasts more than four hours.

Storage

Store ED medications at room temperature, away from moisture and heat. Keep the medication in its original packaging to protect it from light and moisture. Ensure that it is kept out of reach of children and pets.
