I am Dr. Arun and will be helping you today.
I am sorry that your question was unanswered for long.
Adverse effects of Artequin are rare to last for a week; Still there is a possibility of it. Having said that your doctor should get complete blood counts, comprehensive metabolic panel and a x--ray of sinuses for the evaluation.
Another possibility to look for would be dysfunction of the Eustachian tube which can occur due to swelling of the mucosa (internal lining) in the nasopharynx (back portion of the nose which connects with the throat) or in the Eustachian tube, which in turn may occur because of
1) infection or
This swelling can impede the Eustachian tube function. Following medications are used:
1) Decongestants; Sudafed (over the counter)
2) Antihistamines; Chlorpheniramine (Singlet) has best result and available without prescription
3) Steroids; prescription drugs
4) Analgesics; Motrin, Advil, Aleve
Valsalva maneuver (positive pressure against a closed nasal airway) usually equilibrates pressure in the middle ear to the outside and can be helpful if done 5-7 times in a day.
All the above combination may be able to give you certain relief.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
