Hello,

Welcome to the forum. You may feel that you are suffering from the same infection but it may not be true. You should consult a local general physician so that you get physically examined. You need anti- allergic and anti biotics. If you have a prescription and you have been physically examined it will be better.

You should not take any medication by yourself and should follow the doctor's prescription strictly. Do alert your treating doctor if you have history of any past illness or have allergy to some medicines or food. Hope you have the reports ( records ) of your previous investigations with you. It will be helpful for your treatment. You may need a few investigations to be done.

You should have warm saline gargle three times a day. You can also use an antiseptic mouth wash for gargling. Have a nice day. Take care.

Hello dear ...
Thanks for your query.

First of all I would like to say that Deriphyllin[Theophylline] is neither used for infection or allergy.It is used for bronchial asthma & COPD as a bronchodilator.It was given to you to relieve symptoms of bronchospasm.Are you having difficulty in respiration now ?Theophylline has got a narrow margin of safety and multiple sideeffects like gastric pain,dyspepsia,headache,tremors, nausea, palpitation etc. Dont self medicate. Get a check up from a doctor.
If you are having throat infection,watering nose,fever you can use Levotrizine 5 mg tablet twice daily for 5 days. Tablet Paracetamol 500 mg twice daily for 3 days and thereafter sos . Tablet CoAmoxyclav 625 mg thrice daily for 5 days . Tablet Vit C 500 mg twice daily for a week.Do warm saline gurgle 4 times daily for 5 days.

But I dont think you will get medicine without doctor's prescription in USA.

Update here how you stay.
Take care :)
