Viagra

1. Allergic reactions: Do not use Viagra if you are allergic to sildenafil or any of its ingredients. Seek immediate medical attention if you experience signs of an allergic reaction, such as difficulty breathing, swelling of the face, lips, tongue, or throat, or hives.

2. Pre-existing conditions: Inform your healthcare professional about any pre-existing medical conditions, especially heart-related conditions, liver or kidney problems, history of stroke or low blood pressure. Viagra may have potential risks for individuals with these conditions.

3. Medication interactions: Viagra can interact with certain medications, particularly nitrates (commonly used to treat chest pain) and alpha-blockers (used to treat high blood pressure). Combining Viagra with these medications can cause a dangerous drop in blood pressure. Inform your healthcare professional about all the medications you are taking.

4. Priapism: Priapism is a prolonged and painful erection lasting longer than 4 hours. If an erection persists for an extended period, seek immediate medical attention, as priapism can lead to permanent damage if not treated promptly.

5. Vision and hearing changes: In rare cases, Viagra can cause sudden vision or hearing loss. Stop using Viagra and seek medical help if you experience sudden vision or hearing changes.

6. Grapefruit juice: Avoid consuming grapefruit or grapefruit juice while taking Viagra, as it may interact with the medication and increase the risk of side effects.

7. Use as directed: Follow the recommended dosage and instructions provided by your healthcare professional. Do not exceed the prescribed dosage.

It is crucial to consult with a healthcare professional before using Viagra to ensure it is safe and appropriate for you, and to discuss any potential risks or concerns related to your specific health condition or medications.

1. Consultation with a healthcare professional: Before starting Viagra, it is important to consult with a healthcare professional who can evaluate your health, provide personalized guidance, and prescribe the appropriate dosage.

2. Recommended dosage: The typical starting dosage for Viagra is 50mg, but your healthcare professional may adjust it based on your individual needs. The maximum recommended dosage is 100mg per day.

3. Timing of administration: Take Viagra approximately 30 minutes to an hour before engaging in sexual activity. It is best taken on an empty stomach for optimal absorption.

4. Swallow with water: Take the tablet orally with a glass of water. Avoid taking it with grapefruit juice or alcoholic beverages, as they may interfere with the medication's effectiveness.

5. Sexual stimulation required: Viagra enhances the natural response to sexual stimulation, so sexual arousal is necessary to achieve an erection.

6. Frequency of use: Viagra should not be taken more than once a day. Do not exceed the prescribed dosage, as this can increase the risk of side effects.

7. Individual response: The duration of Viagra's effects can vary among individuals, but it generally lasts for around four to five hours. The medication does not prolong or cause continuous erections; it only facilitates the ability to achieve and maintain an erection during sexual activity.

8. Safety precautions: Inform your healthcare professional about any pre-existing medical conditions, ongoing medications (especially those containing nitrates), and any history of allergic reactions. Follow any additional instructions or precautions provided by your healthcare professional.

Always consult with a healthcare professional for personalized advice regarding the appropriate dosage, timing, and usage of Viagra based on your specific circumstances.
