Sidena contains the active substance sildenafil which belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by helping to relax the blood vessels in your penis, allowing blood to flow into your penis when you get sexually excited. Sidena will only help you to get an erection if you are sexually stimulated. Sidena is a treatment for adult men with erectile dysfunction.
Erectile dysfunction, also known as impotence, is an inability to achieve or maintain an erection that is firm enough to have sex. Erections depend on many different factors, including proper blood flow to the penis. Reduced blood flow to the penis may cause erectile dysfunction. Erectile dysfunction can affect men differently. Some cannot achieve an erection. Others may achieve an erection, but not firm enough for having sex or they may lose the erection before or during sex.
Suitable for
Men aged 18 years and older with erectile dysfunction.
Age Restriction You must be at least 18 years old to purchase this product
How to use
Please read the enclosed leaflet carefully before use.
Patient Information Leaflets are updated periodically by the manufacturer.
DIRECTIONS FOR USE
Always take this medicine exactly as described in this leaflet or as your pharmacist or doctor have told you. Check with your pharmacist or doctor if you are not sure.
- Take 1 tablet, as needed, approximately 1 hour before sexual activity.
- Swallow the tablet whole with water.
- Do not take more than 1 tablet a day.
Sidena will only help you achieve an erection if you are sexually aroused. You and your partner should engage in foreplay just as you would if you were not taking a medicine for erectile dysfunction. The amount of time this medicine takes to work varies from person to person, but it normally takes between 30 to 60 minutes. You may take it up to 4 hours before sexual activity.
Relax and be patient if Sidena does not help you the first time. You can try again later but remember you can only take 1 tablet a day. For most men, Sidena will work the first or second time they try it. If it has been some time since you were able to get or keep an erection, it may take a couple of attempts before you achieve the desired effect. Talk to your doctor if you have tried Sidena and are still not able to get and keep an erection.
If you feel the effect of Sidena is too strong, talk to your pharmacist or doctor.
Do not take Sidena tablets in combination with sildenafil containing orodispersible medicines.
Sidena 50 mg
The tablet can be divided into four equal doses. You have to take at least two quarters (corresponding to 25 mg) to reach the minimum effective dose.
Dividing the tablets
Place the tablet on a hard, flat surface with the scoreline facing upwards. Press with your thumb on the middle of the tablet and the tablet breaks into four equal doses.
If you take more Sidena than you should
If you take more tablets than recommended, contact your pharmacist or doctor immediately. Taking more than the recommended dose may result in side effects and/or more severe side effects. You may experience an increase in side effects and their severity. Doses above 100 mg do not increase the efficacy.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
Warning - Do not exceed stated dose
