Can I take Sildenafil and Amlodipine together?

Why this happens

Both medicines work by relaxing and widening your blood vessels to improve blood flow. When used at the same time, their effects add together, which can lead to an extra reduction in blood pressure.

You can usually take these together, but you should be cautious. Start with the lowest possible dose of sildenafil. Stand up slowly from a sitting or lying position to avoid dizziness. If you feel very dizzy or faint, sit or lie down immediately and contact your doctor.

Nitrate medication use (e.g. GTN spray, isosorbide mononitrate)

You must never take sildenafil if you are using nitrate medicines for chest pain or heart problems. Taking them together can cause a sudden, life-threatening drop in blood pressure.

Grapefruit juice consumption

Avoid drinking large amounts of grapefruit juice. It can increase the levels of these medicines in your blood, making side effects like dizziness, headaches, and low blood pressure more likely.

Prolonged erection (Priapism)

If you experience an erection that lasts for more than 4 hours, you must seek immediate medical emergency help to prevent permanent damage to the penis.

Alcohol

Drinking alcohol can make it more difficult to get an erection. Alcohol also lowers blood pressure; combining it with sildenafil can cause your blood pressure to drop significantly, leading to dizziness, lightheadedness, or fainting.

High-fat meals

Taking sildenafil with a very heavy or high-fat meal (such as a burger and chips) can delay the absorption of the medicine. This means it may take much longer than usual to start working.
