Serevent contains the active ingredient salmeterol, which belongs to a group of medicines called long-acting beta-agonists. It works by relaxing the muscles in the airways to help you breathe easier. Serevent is suitable for individuals with asthma or chronic obstructive pulmonary disease (COPD) to help manage and prevent breathing difficulties.

Description
Dosage and usage
For adults and adolescents over 12 years old, the usual dose is 2 puffs taken twice a day. Do not exceed the recommended dose. Serevent should not be used to relieve sudden breathing problems. If your symptoms worsen or do not improve after using Serevent, seek medical advice promptly.
What Serevent contains
Each puff of Serevent contains 25 micrograms of salmeterol (as salmeterol xinafoate) as the active ingredient. The inhaler also contains norflurane (HFA 134a) as a propellant.
Side effects
Common side effects of Serevent may include headache, tremor, or throat irritation. Serious side effects requiring immediate medical attention may include chest pain, increased heart rate, or paradoxical bronchospasm (worsening of breathing). If you experience any of these, seek medical help right away.
Precautions
Do not use Serevent if you are allergic to salmeterol or any other ingredients in the inhaler. It is not recommended for children under 12. If you have heart problems or are taking beta-blockers, consult your healthcare provider before using Serevent. If you experience sudden breathing difficulties, do not use Serevent and seek medical advice promptly.

An excellent experience.
This was an excellent experience which actually surpassed my expectations.I required a medication fairly urgently and probably just a one off however I will have no hesitation in using the service again if need be.The service was exceptionally good, courteous and helpful. My meds arrived very rapidly and I was able to fully track the delivery progress which was via a well established courier company.Highly recommend.
Quick and straightforward assessment
Quick and straightforward assessment, easy to order, fast delivery service, ability to ask questions via email, regarding the medication you’ve ordered. The only thing I was slightly disappointed with, was when I made my second order on the medication I previously purchased, as the price went up by almost £10.
