What Is Cialis?
Cialis is the brand name for tadalafil, a prescription medicine used to treat erectile dysfunction. It works by improving blood flow to the penis when you are sexually aroused. Cialis does not increase sex drive, but it can support a stronger and more reliable physical response.
Cialis is available in different strengths and may be taken as needed or as a daily option for some patients. The best choice depends on your health, lifestyle, and how often you need support.
How Cialis Works in the Body
Cialis belongs to a group of medicines called PDE5 inhibitors. These medicines help blood vessels relax and improve circulation. In erectile dysfunction, this improved blood flow can help you get and maintain an erection when arousal occurs.
Cialis is sometimes called the weekend pill because its effects can last longer than other treatments. More flexibility is often reported, with less need to plan everything so carefully.

How To Take Cialis Safely
Using Cialis safely starts with checking it is suitable for you. Erectile dysfunction can sometimes be linked to underlying health issues, including high blood pressure, diabetes, and heart conditions. Cialis should always be taken exactly as advised.
General Safety Tips
- Only take Cialis if it has been prescribed or approved through a regulated consultation
- Do not take more than the recommended dose
- Avoid mixing Cialis with recreational drugs
- Limit alcohol, as it may reduce effectiveness
- Speak to a clinician if you take other medicines

How Long Does Cialis Take To Work?
Cialis often starts working within 30 to 60 minutes for many patients, but the exact timing can differ. Food does not usually affect Cialis as much as some other ED tablets, but heavy meals may still slow absorption slightly. Taking it with water can support more consistent results.
The effects of Cialis can last up to 36 hours for some patients. This does not mean you will have an erection the whole time, but it can support erections more easily during that window when arousal occurs.
Common Side Effects Of Cialis
Like all medicines, Cialis can cause side effects. Side effects are usually mild and tend to settle as the body adapts. Knowing what to expect can help you feel more prepared when starting treatment.
- Headache
- Facial flushing
- Indigestion
- Blocked nose
- Muscle aches or back pain
- Dizziness
Serious side effects are rare but should be treated as urgent. Seek medical advice straight away if you experience chest pain, sudden vision changes, or a prolonged erection that does not go away.
