Calcium is used for allergies as part of a complex treatment in the form of calcium chloride (calcium salt of hydrochloric acid) and calcium gluconate (calcium salt of gluconic acid), available in the form of powder, tablets, solutions for intravenous injections and oral administration.

Calcium chloride and calcium gluconate are similar in pharmacological action, but it is believed that calcium gluconate can have a less irritating effect. The main treatment with antihistamines when using calcium preparations has an enhanced effect, which is due to the ability of calcium ions to transmit nerve impulses, affect the contraction of smooth muscles, etc. However, the mechanism of the anti-allergic effect of calcium has not been fully studied. It is also known that it can cause stimulation of the sympathetic nervous system and affect the increase in the production of adrenaline by the adrenal glands. Calcium for allergies is prescribed in the absence of such contraindications as thrombosis, atherosclerosis and high calcium levels in the blood.

Calcium supplements for allergies

As is known, calcium preparations for allergies are able to reduce the manifestations of allergic reactions. That is why their use is of particular importance in the treatment of allergies in children, when the skeletal system is not yet fully formed and the body needs to be saturated with calcium. Among calcium preparations, calcium gluconate and calcium chloride are most often used. The absorption of calcium is influenced by parathyroid hormone, calcitonin and vitamin D. For calcium to penetrate into the blood, calcium-binding protein, lysine and L-arginine are also needed. Calcium gluconate preparations are well absorbed into the blood, can dissolve even in cold water and can be used in the treatment of allergies. Calcium chloride preparations can stimulate the sympathetic nervous system, relieve swelling in allergies and neutralize skin rashes.

Calcium chloride for allergies

Calcium chloride can have a good auxiliary effect in allergies, significantly alleviating the manifestations of an allergic reaction. It is used for urticaria, hay fever, immune response to the introduction of foreign serum proteins, angioedema, and allergic reactions caused by the side effects of medications. Calcium chloride increases the secretion of adrenaline into the blood, causing stimulation of the sympathetic nervous system and thereby reducing swelling and eliminating skin rashes. Calcium chloride for allergies is usually taken after meals, 0.5-1 tablespoon of a five- or ten-percent solution two or three times a day. The recommended dose for children is one or two teaspoons. Also, when treating allergies, calcium chloride is slowly dripped into a vein diluted with an isotonic solution of sodium chloride or glucose. Treatment with calcium chloride for allergies is combined with taking antihistamines, such as loratadine, claritin, suprastin, etc. Contraindications to the use of calcium chloride are thrombosis, severe stages of atherosclerosis, and high levels of calcium ions in the blood. Calcium chloride is not injected into the muscle or under the skin, as this is fraught with the formation of tissue necrosis. After taking calcium chloride orally, heartburn and pain in the epigastric region may occur, after intravenous injections, a slowdown in the pulse rate, a feeling of heat in the mouth or throughout the body are possible.

Calcium Gluconate for Allergies

As is known, even a slight lack of calcium in the body can increase the symptoms of an allergic reaction. This is due to the fact that calcium contained in the body in sufficient quantities reduces the permeability of blood vessels, as a result of which the penetration of allergens into the bloodstream is difficult. Consequently, with increased doses of calcium, the likelihood of an immune reaction is reduced. Calcium gluconate for allergies helps to replenish calcium in the body, thereby accelerating the recovery process, is used as an aid in various allergic reactions, including those caused by the side effect of drugs. Calcium gluconate is taken orally before meals. Adults are prescribed from two to six tablets in a dosage of one to three grams two to three times a day. Children aged three to four years - one gram, from five to six years old - 1-1.5 grams, from seven to nine years old - 1.5-2 grams, from ten to fourteen years old - 2-3 grams two to three times a day. Elderly people are not recommended to consume more than two grams of calcium gluconate per day. Side effects when taking calcium gluconate may include nausea, diarrhea, vomiting, epigastric pain, and decreased pulse rate. Calcium gluconate is not used for treatment in cases of renal failure, predisposition to thrombosis or its presence, hypercalcemia, hypercalciuria, and atherosclerosis.

Calcium chloride for allergies

Calcium chloride for allergies (active ingredient Calcium chloride) is used as part of complex therapy in combination with antihistamines to relieve swelling and eliminate skin rashes. This drug belongs to the pharmacological group of micro- and macroelements and can be used for dermatitis and allergies of unspecified etiology, urticaria, hay fever, serum sickness, allergic reactions to drugs. Calcium chloride (or calcium chloride) has an anti-allergic and anti-inflammatory effect, promotes contraction of smooth muscles and can be indicated for use in such complications of allergic origin as itching, eczema, psoriasis, which occur as a side effect when taking medications. Patients who suffer from thrombosis or are prone to it, have a disease such as atherosclerosis or an elevated level of calcium in the blood, in the treatment of allergies, calcium chloride preparations are contraindicated. In addition, when taking calcium chloride, side effects such as hot flashes, slow pulse, and ventricular fibrillation may be observed. Calcium chloride for allergies complements the effect of antihistamines, which is why it is recommended to take them in combination. When treating with calcium chloride, it is unacceptable to administer the drug subcutaneously or intramuscularly. The drug is administered intravenously by jet or drip.
