SECTION 4.8
· The following footnotes have been added:
1 Neutralising antibodies to calcitonin rarely develop. The development of these antibodies is not usually related to loss of clinical efficacy, although their presence in a small percentage of patients following long-term therapy with calcitonin may result in a reduced response to the product. The presence of antibodies appears to bear no relationship to allergic reactions, which are rare. Calcitonin receptor down-regulation may also result in a reduced clinical response in a small percentage of patients following long term therapy.
2Nausea with or without vomiting is noted in approximately 10% of patients treated with calcitonin. The effect is more evident on initiation of therapy and tends to decrease or disappear with continued administration or a reduction in dose. An antiemetic may be administered, if required. Nausea/vomiting are less frequent when injection is done in the evening and after meals.
3In case of patients with high bone remodelling (Paget’s disease and young patients) a transient decrease of calcemia may occur between the 4th and the 6th hour after administration, usually asymptomatic.
4Flushing (facial or upper body)is not an allergic reaction but is due to pharmacological effect, and is usually observed 10 to 20 minutes after administration.
· The following have been added:
The most frequently observed undesirable effects are nausea, vomiting and flushing. They are dose dependent and are more frequent after i.v. than after i.m. or s.c administration.
Headache, dysgeusia, visual disturbance, abdominal pain, polyuria, pruritus, hypertension.
The frequencies of the above listed undesirable effects are partly based on results from clinical trials with Miacalcic Nasal Spray
