Clear rhinorrhoea
Nasal congestion
Sneezing, especially paroxysmal
Itching of nose or throat
Ocular signs – watery, red, itchy eyes

18
Q

Hay fever pharmacological treatments

A

Intranasal corticosteroids (INCSs) –> prevent and treat nasal congestion, sneezing, rhinorrhea (e.g. beclomethasone, budesonide, fluticasone propionate, mometasone)
Intranasal antihistamines –> relieve sneezing, rhinorrhea, nasal itch, nasal congestion (azelastine, levocabastine, olopatadine)
Oral sedating antihistamines (brompheniramine, chlorphenamine, cyproheptadine, dexchlorpheniramine, diphenhydramine, promethazine, triprolidine)
Intranasal decongestants –> relieve nasal congestion (oxymetazoline, phenylephrine, tramazoline, xylometazoline)
Oral decongestants –> relieve nasal congestion (phenylephrine, pseudoephedrine)
Adjunctive treatments (intranasal saline, intranasal ipratropium bromide)

19
Q

Suggestions to prevent symptoms of Hay fever

A

Stay inside when pollen counts are high
Avoid outdoor activities know to lead to exposure of allergens
Shower after outdoor activity
Close car windows
Dry clothes and bedding inside
Keep the house well ventilated
Limit presence of dust-collecting items
Vacuum carpets frequently
Use dust mite-resistant covers

20
Q

When to refer hay fever?

Quality of life is seriously affected
Persistent unilateral nasal obstruction or discharge
Recurrent epistaxis (nosebleeds)
Anosmia (impaired sense of smell)
Signs of asthma - wheezing or shortness of breath
Signs of bacterial infection
Symptoms associated with medicine use
Orbital cellulitis

21
Q

Medical conditions with similar symptoms to allergic rhinitis:

A

Acute rhinosinusitis (common cold)
Chronic rhinosinusitis –> persisting for 12+ weeks / purulent nasal discharge / pain, swelling, pressure around eyes, cheeks, forehead, nose / anosmia
Drug-induced rhinitis –> by aspirin, steroidal anti-inflammatory drugs, vasodilator medicines, estrogens
Rhinitis medicamentosa –> constant nasal congestion not relieved by intranasal decongestants
Non-allergic rhinitis –> absence of itching and ocular signs

22
Q

Management of hay fever during pregnancy and breast feeding

A

Consider alternative of mometasone, desloratadine, fexofenadine in first trimester
Consider alternative azelastine, bilastine, phenylephrine, oral decongestants

23
Q

Hayfever treatment Adverse effects

A
  • Intranasal preparations can cause nasal irritation and nosebleeds
  • oral sedating antihistamines can cause (sedation / paradoxical CNS stimulation / dizziness / dry mouth / constipation / blurred vision
  • less sedating antihistamines can cause sedation
  • oral decongestants (older people) at greater risk of: restlessness / insomnia / tremor / palpitations / increased blood pressure
24

A

Inhibit fungal growth
-bifonazole (cream)

- econazole (cream, liquid)
- ketoconazole (cream, shampoo)
- miconazole (cream, liquid, spray, gel)

29
Q

other antifungals

A

-Terbinafine = inhibits fungal sterol synthesis (cream, gel, liquid, spray)
- Tolnaftate = inhibits fungal growth (powder)

30
Q

antifungals for nail infection

A
  • Amorolfine = inhibits fungal sterol synthesis (liquid)
  • Ciclopirox = fungistatic and fungicidal activity; chelates iron to inhibit fungal growth (liquid)
31
Q

When to refer tinea:

A
  • extensive, severe or persistent infection
  • infection of the scalp, beard or nail matrix
  • lack of response to topical therapy
  • prior treatment with a topical corticosteroid

management of TINEA in children

A
  • terbinafine and amorolfine are NOT recommended for treatment of children < 12
  • ciclopirox is not recommended for children < 18
33
Q

Management of TINEA in pregnancy and breastfeeding

A
  • Bifonazole –> avoid use in pregnancy
  • Ketoconazole –> topical use is safe in pregnancy
  • Terbinafine –> topical use is safe in pregnancy
  • Amorolfine –> consider alternative
  • Ciclopirox –> consider alternative in first trimester
34
Q

Tinea treatment adverse effects

A
  • Azole antifungals, terbinafine, tolnaftate and amorolfine can cause local irritation
