OTC & Self-Care Flashcards

A patient asks for Chloramphenicol eye drops OTC. When should they be referred to a GP?

Answer: If symptoms do not improve within 2 days or if vision is affected

OTC chloramphenicol is for bacterial conjunctivitis. Failure to improve within 2 days, pain, visual disturbance, photophobia, or contact lens wear requires GP referral for further assessment.

Which OTC antihistamine is least sedating and therefore preferred for daytime use?

Answer: Loratadine or cetirizine (second-generation antihistamines)

Second-generation antihistamines (loratadine, cetirizine, fexofenadine) have poor CNS penetration and minimal sedating effects, making them suitable for daytime use without impairment.

A customer requests omeprazole OTC for heartburn. For how long is it recommended before GP review?

Answer: Up to 4 weeks; refer if no improvement or symptoms persist beyond 4 weeks

OTC omeprazole (Nexium Control, Pyrocalm) is licensed for up to 4 weeks for adults with symptomatic gastro-oesophageal reflux. Persistent or worsening symptoms beyond 4 weeks require GP review.

Which OTC product is appropriate for the treatment of athlete's foot (tinea pedis)?

Answer: Clotrimazole cream (Canesten)

Clotrimazole is a topical imidazole antifungal effective against dermatophytes causing athlete's foot. Hydrocortisone is inappropriate (immunosuppressant, worsens fungal infection).

What is the recommended maximum OTC dose of ibuprofen per day for an adult?

Answer: 1200 mg per day (400 mg three times daily)

The OTC maximum for ibuprofen is 1200 mg/day (400 mg three times daily). Prescription doses can go up to 3200 mg/day under medical supervision. OTC use is intended for short-term mild-to-moderate pain.

A customer requests treatment for oral thrush. Which OTC product is first-line?
