Acyclovir is an antiviral drug, a synthetic nucleoside analogue, that has inhibitory activity (interferes with viral replication) against the herpes viruses, including herpes simplex 1 and 2 (cold sores and genital herpes), varicella-zoster (shingles and chickenpox), and Epstein-Barr virus (mononucleosis). Viruses take over living cells and reproduce themselves, often at the expense of the host cell. The acyclovir (Generic Zovirax 800 mg) is converted to an active form by the virus itself, and the virus then uses the active form of acyclovir rather than the nucleoside it normally uses to manufacture DNA, a critical component of viral replication. Incorporation of active acyclovir into new viral DNA stops the production of the DNA.
Take this medication by mouth with or without food, usually 2 to 5 times a day as directed by your doctor. Drink plenty of fluids while taking this medication unless your doctor directs you otherwise. If you are using the liquid form of this medication, shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. This medication works best when started at the first sign of an outbreak, as directed by your doctor. It may not work as well if you delay treatment.
Nausea may occur. If nausea persists or worsens, tell your doctor or pharmacist promptly. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: dizziness, drowsiness, signs of kidney problems (such as a change in the amount of urine, unusual back/side pain), mental/mood changes (such as agitation, confusion, hallucinations), shaky/unsteady movement, trouble speaking. This medication may rarely cause a life-threatening disorder that affects the blood cells, kidneys, and other parts of the body. This disorder is more likely to occur if you have conditions related to a weakened immune system (such as HIV disease, bone marrow transplant, kidney transplant).
Paroxetine belongs to the class of medications called selective serotonin reuptake inhibitors (SSRIs). It is used to treat depression, obsessive-compulsive disorder, panic disorder, social phobia (social anxiety disorder), generalized anxiety disorder, and post-traumatic stress disorder. It works by affecting the balance of chemicals in the brain that are associated with depression and anxiety disorders.
It may take several weeks before the full beneficial effects of this medication are felt. Continue taking the medication until you have consulted with your doctor, even if you feel your symptoms are not improving.
The recommended starting dose is typically Paxil 20 mg once daily (usually in the morning). However, the starting dose for treating panic disorder and for elderly people or people with liver or kidney problems will be lower. If symptoms continue, your healthcare provider may choose to increase to Paxil 30 mg dosage. If side effects occur, the dosage may be decreased.
The maximum Paxil dose is 50 mg (for depression, generalized anxiety disorder, or post-traumatic stress disorder) or 60 mg (for social anxiety disorder, panic disorder, or obsessive-compulsive disorder).
