Please could someone give me some advice? I need to treat my guinea pig for a fungal infection. I have been to the vets and the guinea pig was given Dexadreson (a cortico-steroid injection) and a topical cream Aurimic. I noticed fresh scratching has taken place after treating him for three days with the cream. As the vet's consultation came to £75, that has left me wondering if I have spent my meagre funds wisely. I know that itrafungol is widely recommended but it costs something over £60 and needs a prescription which my vet will charge me £12 for supplying. Imaverol dip is also recommended - also pricey but at least it is an over the counter item. Would this be OK to use on its own? I don't think I can afford to buy both products. Up to now I have been using Gorgeous Guinea Neem and Manuka shampoo and lotions. These have helped but not eradicated the problem which has been going on for months now due to the fact I am an inexperienced owner and didnt recognise the need to control an outbreak of hair loss as soon as it started occuring. A second guinea pig has lost hair around her face and needs treating as well. I hope someone can advise - I realise I haven't had a definitive diagnosis from any vet on whether the infection is ringworm or not (been to two or three vets now about this same problem).
