Compounded Tadalafil Chewable Tablet

1. What are Tadalafil Chewable Tablets and what are they used for 

Tadalafil Chewable Tablets contain the active substance tadalafil, which belongs to a class of medicines called phosphodiesterase type 5 (PDE5) inhibitors. They are used for the treatment of erectile dysfunction in adult men, a common condition which implies difficulties in getting or keeping an erection. There may be physical or psychological causes for ED, or a mixture of both. If a medical provider determines it to be safe and appropriate, PDE5 inhibitors can also be used to treat premature ejaculation and to improve overall sexual quality of life. They can also help you get another erection more easily after orgasm.

Tadalafil Chewable Tablets will only work when you are sexually stimulated. They reduce the action of the natural chemical in your body that makes erections go away. Tadalafil Chewable Tablets allow an erection to last long enough for you to satisfactorily complete sexual activity.

This is a compounded prescription product and has not been approved by the MHRA.

2. What you need to know before you take Tadalafil Chewable Tablets 

Do not take Tadalafil Chewable Tablets 

  • If you are allergic to tadalafil or any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction include a rash, itching, swollen face or lips and shortness of breath.

  • If you are taking any form of organic nitrate or nitric oxide donors such as amyl nitrite. This is a group of medicines (“nitrates”) used in the treatment of angina pectoris (“chest pain”). Tadalafil has been shown to increase the effects of these medicines. If you are taking any form of nitrate or are unsure, tell your clinician.

    • If you have serious heart disease or recently had a heart attack within the last 90 days.

    • If you have recently had a stroke within the last 6 months.

    • If you have ever had a condition involving loss of vision due to damage to the optic nerve from insufficient blood supply known as non-arteritic ischemic optic neuropathy (NAION). 

    • If you are taking riociguat. This drug is used to treat pulmonary arterial hypertension (i.e. high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension (i.e. high blood pressure in the lungs secondary to blood clots). PDE5 inhibitors, such as Tadalafil Chewable Tablets have been shown to increase the hypotensive effects of this medicine. If you are taking riociguat or are unsure, tell your pharmacist or medical provider.
